DV-5AAutomatic Water Control Valve, Single
Interlock Preaction, Dry Pilot Actuation, Fire
Protection System 1 1/2 to 8 Inch (DN40 to DN200)
General
Description
The TYCO DV-5AAutomatic Water
Control Valve Single Interlock Preaction
Dry Pilot Actuation is a diaphragm type
valve that can be used in single inter-
lock preaction fire protection systems.
When properly trimmed, the double
seat design of the DV-5AValve also
provides actuation of fire alarms upon
system operation.
The diaphragm style design of the
DV-5AValve allows external resetting,
providing for easy resetting of a deluge
system without having to open a valve
handhole cover to manually reposition
a clapper and/or latch mechanism.
Simply re-pressurizing the diaphragm
chamber resets the valve.
The DV-5Afeatures internal and exter-
nal coating of the valve to provide
corrosion resistance. The external cor-
rosion resistance of the epoxy coating
permits the use of the DV-5Ain cor-
rosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.
The DV-5ASingle Interlock Preaction
Dry Pilot Actuation Valve is offered
with the DV-5AValve and separately
ordered semi-assembled trim as shown
in Figure 5 for ease of installation.
The DV-5ASingle Interlock Preaction
Dry Pilot Actuation Valve is offered
with or without a System Main Control
Valve.
The DV-5ASingle Interlock Preaction
Dry Pilot Actuation Valve utilizes auto-
matic sprinklers and a supplemental
detection system, comprised of dry
pilot lines. Actuation of the detec-
tion system automatically operates
(releases) the DV-5AValve, allowing
water to flow into the sprinkler piping
system and to be discharged from any
sprinklers that may subsequently open.

DV-5AVALVE OPERATION, PREACTION SYSTEMS

TFP1416
Page 4 of 18
Typically, the system designer selects
the detection components for a single
interlock preaction system that will
respond to a fire sooner than the auto-
matic sprinklers. Consequently, the
system will experience a minimal delay
in water delivery over that for a wet pipe
sprinkler system because the system
will have essentially filled with water
before a sprinkler operates. The DV-5A
Single Interlock Preaction Dry Pilot-
Actuation Valve automatically super-
vises the integrity of the overall system.
Supervision is provided by monitoring a
relatively low air pressure in the system
via a low pressure alarm switch so as
to detect leaks in the system that oth-
erwise would result in unwanted water
discharge should the system operate in
a fire condition.
Supervised single interlock preac-
tion systems are generally used to
protect areas where there is danger
of serious water damage that might
result from damaged automatic sprin-
klers or piping. Typically, such areas
include computer rooms, storage
areas for valuable artifacts, libraries,
and archives.
Single interlock preaction systems are
also effectively used to protect proper-
ties where a pre-alarm of a possible fire
condition may allow time for fire extin-
guishment by alternate suppression
means, prior to a sprinkler discharge.
In the event the fire cannot otherwise
be extinguished, the preaction sprinkler
system will then perform as the primary
fire protection system.
NOTICE
The DV-5Asingle interlock preaction
dry pilot actuation valve described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the NATIONAL FIRE PRO-
TECTION ASSOCIATION (NFPA), in
addition to the standards of any other
authorities having jurisdiction. Failure
to do so may impair the performance
of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

DV-5ASingle Interlock Preaction Dry Pilot
Actuation Valve being trimmed as described
in Figure 5.
DV-5AValve
Components for the 1 1/2 in. to 8 in. (DN40 to
DN200) DV-5AValves are shown in Figure 1.
The DV-5AValves is for vertical installations.
It is rated for use at service pressures of 20
to 300 psi (1,4 to 20,7 bar).
The take-out dimensions are shown in
Figure 3, and flanged connections are
available drilled per ANSI, ISO, AS, and JIS
specications (See Table A). Threaded inlet
and outlet connections are available in NPT
or ISO 7-1. Threaded port connections are
NPT threaded.
Note: PN16 flanges are pressure rated to
16 bar.
Valve Trim
The maximum pressure rating for the single
interlock preaction dry pilot actuation trim
is 250 psi (17,2 bar).
When the system pressure is greater than
175 psi (12,1 bar), provision is to be made
to replace the standard order 300 psi (20,7
bar) water pressure gauges with separately
ordered 600 psi (41,4 bar) water pressure
gauges.
If the addition of an alarm control Valve is
desired or required by the local AHJ, the
alarm control valve noted as Item H in Figure
8 is to be a separately ordered electronically
supervised normally open valve.
External trim connections are NPT threaded.
EMEA trim is provided with NPT x ISO 7-1
thread adapters.

System Air Pressure Requirements
The supervisory air (nitrogen) pressure is to
be 10 ± 2 psi (0,69 ±0,07 bar). The use of
a higher supervisory pressure is subject to
approval by the authority having jurisdiction,
and it should be understood that the use of
a higher supervisory pressure may increase
water delivery time. The use of a lower
supervisory pressure may prevent clearing
the alarm of the supervisory low pressure
switch (Item T - Figure 8), which is factory
set to alarm at 5 ± 1 psi (0,34 ± 0,07 bar) on
decreasing pressure. The supervisory air
supply pressure of 10 ± 2 psi (0,69 ± 0,07 bar)
can be provided by any of the following
methods. Refer to the applicable data sheet
for laboratory approval information.

Operation
The TYCO DV-5AValve is a diaphragm
style valve that depends upon water
pressure in the diaphragm chamber,
see Figure 2A, to hold the diaphragm
closed against the water supply
pressure.
When the DV-5Avalve is set for service,
the diaphragm chamber is pressurized
through the trim connections from the
inlet side of the system’s main control
valve.
Opening the dry pilot actuation trips the
Model MRA-1 manual reset actuator.
Tripping the MRA-1 releases water from
the DV-5Adiaphragm chamber faster
than it can be replenished through a
1/8 in. (3,2 mm) restriction located in
the diaphragm chamber supply con-
nection. Release of water through the
MRA-1 results in a rapid pressure drop
in the DV-5adiaphragm chamber. The
force differential applied through the
diaphragm to hold the diaphragm in
the set position is then reduced below
the valve trip point. The water supply
pressure then forces the diaphragm
open permitting water to flow into the
system piping, as well as through the
alarm port to actuate the system alarms
(See Figure 2B).
Upon opening of the DV-5Avalve, the
Model MRA-1 manual reset actuator
opens to constantly vent the DV-5Adia-
phragm chamber to hydraulically latch
the DV-5Ain the tripped position until
manually reset.
In standby mode, the integrity of the
system piping is supervised by a low
pressure alarm switch.
See the Dry Pilot Actuation sections for
additional information.
Dry Pilot
Actuation
The dry pilot actuation trim forms a part
of the laboratory approval of the DV-5A
valves and is necessary for their proper
operation.
With reference to Figure 4, the dry pilot
actuation trim provides for installation
of a detection system consisting of pilot
sprinklers (heat detectors) and manual
control stations interconnected with
a minimum length of 56 ft (17,1 m) of
1/2 in. (DN15) steel pipe equivalent to
207 in.3(3400 cm3). The dry pilot line,
which is to be pressurized with air or
nitrogen, is connected to the dry pilot
line connection.
Dimensions are provided in Figure 7.
Pilot sprinklers are to be minimum 5.6
K-factor (80 K-factor) orifice approved
automatic sprinklers. Manual control
stations are to be the Model MC-1
described in Technical Data Sheet
TFP1382.
Note: For single interlock preaction
systems with dry pilot actuation, the
system designer typically selects dry pilot
sprinklers that will operate sooner than the
automatic sprinklers chosen for use on the
sprinkler piping.
Provision must be made for installing
a 5.6 K-factor (80 K-factor) inspector's
test connection at the most remote
location on the dry pilot line.
The dry pilot actuation trim is provided
with a Model DP-1 dry pilot actuator,
which is described in Technical Data
Sheet TFP1380. The actuator is rated
for use at a maximum pilot service
pressure of 50 psi (3,4 bar) and a
maximum water supply service pres-
sure of 250 psi (17,2 bar).
Graph B shows the minimum pilot line
service pressure as a function of the
water supply pressure. The pressure in
the dry pilot actuation system must be
automatically maintained using one of
the following maintenance devices, as
appropriate.

NOTES:
The dew point of the pilot line air pressure must be maintained
below the lowest ambient temperature to which the dry pilot
actuation system will be exposed. Accumulation of water in the
pilot line connection to the Actuator will lower the air pressure
at which the actuator will open and possibly prevent proper
operation. Also, introduction of moisture into the pilot lines
exposed to freezing temperatures can create an ice buildup
that could prevent proper operation of the Actuator.
An air dryer must be installed where the moisture content
of the air supply is not properly controlled at less than the
required value.
It is recommended that an AMD-3 Nitrogen Maintenance
Device be utilized in dry pilot actuation system applica-
tions where the dew point must be maintained below -20°F
(-29°C). Refer to Technical Data Sheet TFP1241.
• Model AMD-1 air maintenance
device (pressure reducing type), refer
to Technical Data Sheet TFP1221
• Model AMD-2 air maintenance device
(compressor control type), refer to
Technical Data Sheet TFP1231
• Model AMD-3 nitrogen maintenance
device (high pressure reducing
type), refer to Technical Data Sheet
TFP1241
Supervision of the pressure in the dry
pilot actuation system and an alarm
that separately indicates operation of
the detection system is provided by
a low pressure alarm switch set as
follows:
• Low pressure alarm setting at
approximately 6 psi (0,4 bar) below
the minimum pilot line service pres-
sure requirement shown in Graph B
• Fire alarm setting at approximately
15 psi (1,0 bar) below the minimum
pilot line service pressure require-
ment shown in Graph B
The dry pilot air pressure relief valve
provided in the trim is factory set to
relieve at a pressure of approximately
45 psi (3,1 bar); however, it may be
field adjusted to a lower pressure, if
required.
The dry pilot line is to be provided with
low point drains to enable draining of
condensate.
Note: At a minimum, it is recommended
thatinternally galvanized pipe and castiron
fittings be used for dry pilot lines.
Installation
The TYCO DV-5ASingle Interlock Pre-
action Dry Pilot Actuation Valve is to
be installed in accordance with this
section.
NOTICE
DV-5AAutomatic Water Control Valves
are designed to be used in freshwa-
ter systems. When the supply is from
an alternative source such as brackish
water, saltwater, or contains additives
such as foam, the limited warranty is
reduced to one year from the time of
installation. An increase in frequency of
inspections is required when the valve
is exposed to such supplies and other
corrosive conditions or chemicals that
could impact valve materials or the
operation of the assembly. The system
and all components must be designed
accordingly for the increased demand.
It is required to thoroughly flush the
valve and trim assembly with freshwa-
ter and reset to the set condition after
each operation.
Proper operation of the DV-5Asingle
interlock preaction dry pilot actua-
tion valve depends upon their trim
being installed in accordance with the
instructions given in this technical data
sheet. Failure to follow the appropriate
trim diagram may prevent the DV-5A
valve from functioning properly, as well
as void approvals and the manufactur-
er’s warranties.
The DV-5Avalve must be installed in a
readily visible and accessible location.
The DV-5Avalve, associated trim, and
wet pilot lines must be maintained at
a minimum temperature of 40°F (4°C).
Heat tracing of the DV-5Avalve or its
associated trim is not permitted. Heat
tracing can result in the formation of
hardened mineral deposits that are
capable of preventing proper operation.
Always open the system control valves
slowly to avoid a sudden rush of water
entering the system.
The DV-5Avalve is to be installed in
accordance with the following criteria:
Step 1. All nipples, fittings, and devices
must be clean and free of scale and
burrs before installation. Use pipe
thread sealant sparingly on male pipe
threads only.
Step 2. The DV-5Asingle interlock pre-
action dry pilot actuation valve must be
trimmed in accordance with the trim
illustrations shown in Figure 5.
Note:If the addition of an alarm control
valve is desired or required by the local
AHJ, the alarm control valve noted as
Item H in Figure 8 is to be a separately
orderedelectronicallysupervised normally
open valve.
Step 3. Care must be taken to ensure
that check valves, strainers, globe
valves, etc. are installed with the flow
arrows in the proper direction.
Step 4. Drain tubing to the drip funnel
must be installed with smooth bends
that will not restrict flow.
Step 5. The main drain and drip funnel
drain may be interconnected provided
a check valve is located at least 12 in.
(300 mm) below the drip funnel.
Step 6. Suitable provision must be
made for disposal of drain water. Drain-
age water must be directed such that
it will not cause accidental damage to
property or danger to persons.

Step 7. Connect the diaphragm supply
valve to the inlet side of the system
main control valve in order to facilitate
setting of the DV-5Avalve (See Figure
8).
Step 8. An inspector’s test connection,
as described in the dry pilot actuation
section, must be provided for dry pilot
actuation systems.
Step 9. An air maintenance device,
as described in the dry pilot actuation
section, must be provided for dry pilot
actuation.
Step 10. A desiccant dryer, when
specified for dry pilot actuation, is to
be installed between a drip leg and the
air maintenance device.
Step 11. The low pressure alarm switch
for dry pilot actuation is to be adjusted
as follows:
• Low pressure alarm setting at
approximately 6 psi (0,4 bar) below
the minimum pilot line service pres-
sure requirement shown in Graph B
•
Fire alarm setting at approximately
15 psi (1,0 bar) below the minimum
pilot line service pressure require-
ment shown in Graph B
Step 12. Unused pressure alarm switch
connections must be plugged.

Step 10. After allowing water to flow
out of the manual reset actuator (N)
drain tube until aerated water ceases
to discharge, reset the manual reset
actuator (N) by pressing the reset knob
and hold until water stops flowing from
its drain tube and the pressure builds
and reaches approximately 15 psi (1,0
bar) on the diaphragm gauge (K). Pres-
sure will then build up in the DV-5adia-
phragm chamber.
Note: After relieving trapped air, check
the manual reset actuator (N) to make sure
there is no water draining from its drain
tube. If water is draining, reset the manual
reset actuator (N) as previously instructed.
Step 11. Verify the ability for the DV-5A
diaphragm to hold pressure as follows:
•
With the diaphragm chamber pres-
surized per Step 10, temporarily
close the diaphragm supply valve
(P), and then observe the diaphragm
gauge (K) for a drop in pressure.
•
If a drop in pressure is noted, the
DV-5Adiaphragm is to be replaced
and/or any leaks must be corrected
before proceeding to the next step.
•
If the diaphragm gauge (K) indicates
no drop in pressure, re-open the
diaphragm supply valve (P) and
proceed to the next step.
Step 12. Open the supervisory air
supply valve (S) to reestablish supervi-
sory system air pressure at nominally
10 psi (0,68 bar).
Step 13. Partially open the system
main control valve (B). Slowly close the
main drain valve (D) as soon as water
discharges from the main drain valve
(D). Observe the automatic drain valve
(F) for leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem before proceeding.
NOTICE
When the system main control valve
(B) is partially opened, the pressure
on the DV-5Adiaphragm chamber may
increase. This increase in pressure is
normal, and if the pressure is greater
than 300 psi (20,7 bar), the pressure is
to be relieved by partially and temporar-
ily opening the manual control station
(M); however, do not allow the pressure
as indicated on the diaphragm gauge
(K) to drop below the supply pressure
shown on the water supply gauge (J),
since this action may result in tripping
of the DV-5Avalve.
Valve Setting
Procedure
Perform Steps 1 through 16 when ini-
tially setting the TYCO DV-5AValve,
after an operational test of the fire pro-
tection system, or after system opera-
tion due to a fire. See Figure 8.
Step 1. Close the system main control
valve (B).
Step 2. Close the diaphragm supply
valve (P) and close the dry pilot air
supply valve (W).
Step 3. Close the supervisory air
supply valve (S).
Step 4. Open the main drain valve (D),
system drain valve (E), and all auxiliary
drains in the system. Close the auxiliary
drain valves and the system drain valve
(E) after water ceases to discharge.
Leave the main drain valve (D) open.
At this time make certain that the pres-
sure gauge valves and the alarm control
valve (H), as applicable, are open.
Step 5. Depress the plunger of the
automatic drain valve (F) to verify that
it is open.
Step 6. Clean the diaphragm supply
strainer (Q) by removing the clean-
out plug and strainer basket. The dia-
phragm supply strainer (Q) may be
flushed out by momentarily opening
the diaphragm supply valve (P).
Step 7. Replace any operated sprin-
klers on the system piping, as
applicable.
Step 8. Reset the automatic actuation
system. Replace operated pilot sprin-
klers and/or reset the remote manual
control stations. Reestablish dry pilot
pneumatic pressure.
NOTICE
In order to prevent the possibility of a
subsequent operation of an overheated
solder type pilot sprinkler, any solder
type pilot sprinklers that were possibly
exposed to a temperature greater than
their maximum rated ambient must be
replaced.
Step 9. Operate (open) the manual
control station (M) and then open
the diaphragm supply valve (P). After
unaerated water ceases to discharge
from the manual control station (M)
drain tube, slowly close the operating
lever by pushing it up. Do not close the
hinged cover at this time.
Step 13. The dry pilot pressure relief
valve (Item Y - Figure 8) provided with
the dry pilot actuation trim is factory
set to relieve at a pressure of approxi-
mately 45 psi (3,1 bar), which can typi-
cally be used for a maximum dry pilot
actuation system pressure of 40 psi
(2,8 bar). The pressure relief valve may
be reset; however, it must be reset to
relieve at a pressure which is in accor-
dance with the requirements of the
authority having jurisdiction.
To reset the dry pilot pressure relief
valve, first loosen the jam nut and then
adjust the cap accordingly, clockwise
for a higher pressure setting or counter
clockwise for a lower pressure setting.
After verifying the desired pressure
setting, tighten the jam nut.
Step 14. A suitable automatic supervi-
sory air (nitrogen) supply, as described
in the Technical Data section, is to be
installed in accordance with the appli-
cable technical data sheet and set for
10 ± 2 psi (0,69 ± 0,14 bar).
Step 15. A desiccant dryer, when
required for the supervisory air supply,
is to be installed between a drip leg
and the Model AMD-1 air mainte-
nance device or between the Model
G16AC812 automatic supervisory air
supply and the preaction trim.
Step 16. The supervisory low pressure
switch is to be wired to the supervisory
alarm initiating circuit of an alarm panel.
Step 17. Conduit and electrical con-
nections are to be made in accordance
with the applicable standards of the
approval agency.
Step 18. Before a system hydrostatic
test is performed, the DV-5Adiaphragm
chamber is to be depressurized, the
automatic drain valve is to be tem-
porarily replaced with a plug, and the
diaphragm cover bolts must be uni-
formly and securely tightened using
a cross-draw sequence.After tight-
ening, double-check to make certain
that all of the diaphragm cover bolts
are securely tightened. See Table B in
the Care and Maintenance section for
torque specifications.
Note: When installing dry pilot actuation,
the system will require two automatic air
supplies as described in Steps 9 and 14.

Step 14. Close the hinged cover of the
manual control station (M) and insert a
new break rod in the small hole through
the top of the enclosing box.
Step 15. Fully open the system main
control valve (B).
Step 16. After setting a fire protec-
tion system, notify the proper authori-
ties and advise those responsible for
monitoring proprietary and/or central
station alarms.
Care and
Maintenance
The following procedures and inspec-
tions must be performed as indicated,
in addition to any specific require-
ments of the NFPA and any applicable
standards recognized by the Approval
agency. Any impairment must be imme-
diately corrected. See Figure 8.
NOTICE
If the water supply needs to be shut off
to the DV-5Avalve and trim and cannot
be shut off upstream of the system,
close the system main control valve (B),
the diaphragm supply valve (P), and the
inverted flare shut-off valve (R). This will
allow any trim above the system main
control valve (B) to be taken apart for
service if necessary.
The frequency at which the following
procedures and inspections are to be
performed are to be in accordance with
the NFPA and any applicable specific
requirements of the standards recog-
nized by the Approval agency.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down
the affected fire protection systems
must first be obtained from the proper
authorities and all personnel who may
be affected by this action must be
notified.
The owner is responsible for the
inspection, testing, and maintenance
of their fire protection system and
devices in compliance with this docu-
ment, as well as with the NFPA and any
applicable standards recognized by the
Approval agency. Contact the install-
ing contractor or product manufacturer
with any questions.
Some procedures in this section result
in the operation of the associated
alarms. Notify the owner and the fire
department, central station, or other
signal station to which the alarms are
connected before performing the tests.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with the
NFPA and any applicable standards
recognized by the Approval agency.
Drop in Water Supply Pressure
Below Normal Range
NOTICE
If the water supply pressure is signif-
icantly reduced below the normally
expected static pressure range (as
could occur in the case of a water main
break or repair), and there is a subse-
quent drop in the diaphragm chamber
water pressure below its normal range
(for example, due to a leak in a piping
connection to or from the diaphragm
chamber or, a leak in the diaphragm
chamber check valve caused by dirt or
debris in the check valve seal area), a
deluge valve such as the DV-5Acould
inadvertently trip, if its water supply
pressure is quickly restored.
A drop in the water supply pressure
to below its normal range (as in the
case of an interrupted water supply
condition) constitutes an emergency
impairment.
Should this condition occur, immedi-
ately close the system main control
valve (B) and use the following proce-
dure to reset the system:
Step 1. Prior to the water supply pres-
sure being restored to the closed
system main control valve (B), note the
pressure indicated by the diaphragm
gauge (K) and determine if the pressure
is within the normally expected range.
Step 2. If the diaphragm chamber pres-
sure is below the normal range, check
for and correct any source of leakage
from the diaphragm chamber prior to
resetting the system.
Step 3. After the water supply pres-
sure is restored to the system main
control valve (B), reset the DV-5Avalve
in accordance with the Valve Setting
Procedure section.
NOTICE
For fire protection systems subject to
an emergency impairment caused by
an interrupted water supply condition,
it is recommended that consideration
be given to installing a low water supply
pressure switch with the appropriate
alarm/indications to monitor the water
supply pressure.
Waterflow Alarm Test Procedure
To test the waterflow alarm, open the
alarm test valve (G), which will allow a
flow of water to the waterflow pressure
switch (C) and/or water motor alarm.
Upon satisfactory completion of the
test, close the alarm test valve (G).
To ensure drainage of the alarm line,
depress the plunger on the automatic
drain valve (F).
Supervisory Low Pressure Alarm
Test Procedure
Proper operation of the supervisory low
pressure switch (U) must be performed
as follows:
Step 1. Open the system drain valve
(E) just enough to slowly relieve super-
visory air pressure from the system.
Verify that the supervisory low pressure
switch (U) is operational and that the
low pressure set point is approximately
5 psi (0,34 bar).
Step 2. Close the system drain valve
(E) and allow the system supervisory
pressure of 10 ± 2 psi (0,69 ± 0,14 bar)
to be automatically re-established. The
supervisory low pressure switch (U)
should return to its normal condition.
Pressure Relief Valve Maintenance
Over pressurization of the system
piping with air will result in the opening
of the supervisory air pressure relief
valve (T). If the supervisory air pres-
sure relief valve (T) continues to bleed
air after the system pressure has
been reduced to its normal super-
visory pressure range of 10 ± 2 psi
(0,69 ± 0,14 bar), most likely debris
became lodged in the seating area. To
help clean the seating area, slowly pull
up on the ring at the top of the supervi-
sory air pressure relief valve (T) to allow
a full flow of air through the supervisory
air pressure relief valve (T), and then
release the ring to allow the supervi-
sory air pressure relief valve (T) to snap
closed. Repeat the cleaning procedure
as necessary.

Dry Pilot Actuation
Operation Test Procedure
Proper operation of the DV-5Avalve,
such as opening of the DV-5Avalve as
during a fire condition, must be verified
as follows:
Step 1. If water must be prevented
from flowing beyond the riser, perform
the following steps:
• Close system main control valve (B).
Open main drain valve (D).
• Open system main control valve (B)
one turn beyond position at which
water just begins to flow from main
drain valve (D).
• Slowly close the main drain valve (D).
Step 2. Open the inspector’s test
connection.
Note: Be prepared to quickly perform Steps
3, 4, and 5 if water must be prevented from
flowing beyond the riser.
Step 3. Verify that the DV-5Avalve has
tripped, as indicated by the flow of
water into the system.
Step 4. Close the system main control
valve (B).
Step 5. Close the diaphragm supply
valve (P).
Step 6. Reset the DV-5Avalve in accor-
dance with the Valve Setting Procedure.
Dry Pilot Actuator Test Procedure
Proper operation of the dry pilot actua-
tor for dry pilot actuation must be veri-
fied as follows:
Step 1. Close the system main control
valve (B).
Step 2. Open the main drain valve (D).
Step 3. Open the inspector’s test con-
nection on the dry pilot line.
Step 4. Verify that there is a flow of
water from the dry pilot actuator (U)
drain connection.
Step 5. Verify that the diaphragm
chamber pressure has decreased
to below 25% of the water supply
pressure.
Step 6. Close the inspector’s test con-
nection and allow the dry pilot line
pressure to re-establish, and proceed
as follows:
• Water should cease draining from
the dry pilot actuator (U) but remain
draining from the manual reset actu-
ator (N).
• Press the reset knob on the manual
reset actuator (N) and hold it a few
seconds until water stops flowing
from its drain valve.
• Pressure will then build up in the
DV-5Adiaphragm chamber.
• After system pressure is restored
in the DV-5Adiaphragm chamber,
inspect the Dry pilot actuator (U) and
manual reset actuator (N) for leaks at
the drain tubes. Any leaks must be
corrected before proceeding to the
next step.
Step 7. Partially open the system main
control valve (B). Slowly close the main
drain valve (D) as soon as water dis-
charges from the main drain valve (D)
and then close the main drain valve
(D). Observe the automatic drain valve
(F) for leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem. If there are no leaks, the
DV-5Avalve is ready to be placed in
service and the system main control
valve (B) must then be fully opened.
Low Pressure Alarm and
Condensate Drain for Dry Pilot
Actuation Test Procedures
Testing of the dry pilot low pressure
switch (W) and drainage of the pilot
line condensate must be performed as
follows:
Step 1. Close the system main control
valve (B).
Step 2. Close the diaphragm supply
valve (P).
Step 3. Open the main drain valve (D).
Step 4. Open the inspector’s test con-
nection, and slowly relieve pneumatic
pressure. Verify that the dry pilot low
pressure switch (W) is operational and
that the low pressure set points are as
follows:
• Low pressure alarm setting at
approximately 6 psi (0,4 bar) below
the minimum pilot line service pres-
sure requirement shown in Graph B
• Fire alarm setting at approximately
14.5 psi (1,0 bar) below the minimum
pilot line service pressure require-
ment shown in Graph B.
Step 5. Close the inspector’s test con-
nection and allow the dry pilot line to
automatically repressurize.
Step 6. Individually open each low
point drain and then close after dis-
charge of any trapped condensate.
The gauge test valve to which the dry
pilot line gauge (Y) is connected must
be used as a low point drain. Close the
gauge test valve, remove the plug, and
partially open the gauge test valve (as
necessary, collect water in a cup). After
condensate water ceases to drain,
close the gauge test valve, replace the
plug, and then completely open the
gauge test valve.
Step 7. Allow the dry pilot line to auto-
matically repressurize.
Step 8. Open the diaphragm supply
valve (P).
Step 9. Partially open the system main
control valve (B). Slowly close the main
drain valve (D) as soon as water dis-
charges from the main drain valve (D).
Observe the automatic drain valve
(F) for leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem. If there are no leaks, the
DV-5Avalve is ready to be placed in
service and the system main control
valve (B) must then be fully opened.

Internal Valve Inspection
Once every five years during the annual
operational test procedure and prior
to the DV-5Avalve being reset and
with the DV-5Avalve de-pressurized,
the interior of the DV-5Avalve must
be cleaned and inspected for wear
and damage. Damaged or worn parts
must be replaced. Replacement of the
Diaphragm every ten years is recom-
mended, or more frequently if inspec-
tions and/or wear and tear warrant
more frequent replacement.
NOTICE
The diaphragm cover may be removed
between Steps 4 and 5 of the reset-
ting instructions, since at that point the
DV-5avalve should be de-pressurized
as evident by a zero gauge reading on
the diaphragm gauge (K) and water
supply gauge (J), as well as no water
discharging from the automatic drain
valve (F).
To perform internal valve inspection
between Steps 4 and 5 of the Valve
Setting Procedure remove the dia-
phragm cover as follows:
Step 1. Close the inverted flare shut-
off valve (R).
Step 2. Remove the copper tube fitting
between the diaphragm supply valve
(P) and the inverted flare shut-off valve
(R).
Step 3. Loosen the union securing the
dry pilot actuation trim, and remove the
dry pilot actuation trim.
Step 4. Loosen and remove the union
between the diaphragm cover and the
MRA-1 manual reset actuator (N) and
remove the MRA-1 manual reset actua-
tor (N) subassembly.
Step 5. Remove the diaphragm valve
cover hardware, then slowly remove the
diaphragm cover and perform internal
valve inspection. Clean the valve inte-
rior and replace parts as necessary.
After cleaning and inspecting valve
interior, and replacing parts as nec-
essary, reinstall the diaphragm cover
by completing the following steps to
assure the diaphragm cover fasteners
are uniformly and securely tightened.
Step 1. With reference to Figure 1,
ensure that the diaphragm is properly
oriented and that the proper hardware
arrangement is utilized when assem-
bling the diaphragm covers. The hard-
ware arrangements differ depending on
the size of the DV-5Avalve.
Step 2. By first using the long hex bolts,
support of the diaphragm cover will be
provided before installing the short hex
bolts. Align diaphragm in proper orien-
tation with valve body, and then align
diaphragm cover in proper orienta-
tion with valve body. Hand-tighten all
fasteners.
Step 3. Using crossdraw sequence to
assure uniformity, wrench-tighten long
hex Bolts and short hex bolts to appro-
priate torque values. Repeat crossdraw
sequence two to three times at incre-
mental torque valves until reaching the
torque valves found in Table B.
Step 4. Inspect to assure all hex bolts
are securely tightened.
Step 5. Using the union, secure the
MRA-1 manual reset actuator (N) to the
diaphragm cover.
Step 6. Using the union, secure the dry
pilot actuation trim.
Step 7. Replace the copper tube fitting
between the diaphragm supply valve
(P) and the inverted flare shut-off valve
(R).
Step 8. Ensure that the unions and flare
fittings are securely tightened.
Step 9. With the diaphragm supply
valve (P) closed, fully open the inverted
flare shut-off valve (R) stainless steel
screw (approximately ½ in.) until resis-
tance is met so as not to break the
internal roll-pin. The internal roll-pin
stops the removal of the inverted flare
shut-off valve (R) stainless steel screw.
Step 10. Proceed with Step 5 of the
Valve Setting Procedures section in this
data sheet.
NOTICE
If the water supply contains chemicals
which tend to attack a polyester fab-
ric-reinforced, EPDM rubber or the five
year inspection indicates a build-up of
debris within the DV-5Avalve that could
affect its proper operation, then the
frequency of the internal valve inspec-
tion procedure must be appropriately
increased.
With reference to Figure 1, make
certain that the diaphragm is correctly
oriented; otherwise, the DV-5Avalve
cannot be properly set.
Under-tightening the diaphragm cover
bolts can result in internal and external
leakage.
Use only TYCO replacement fasteners
as specified in Figure 1.
Do not apply adhesives, lubricants,
or other substances to the diaphragm
valve body.

Description
The appendix found at the end of this
document provides valve setting and
testing/inspection procedures summa-
rized from the Care and Maintenance
section.
Some jurisdictions require a copy of the
Summary Instructions appendix to be
displayed in proximity to a DV-5AAuto-
matic Control Valve riser supplying a
fire protection system.
Reproduce as an individual poster by
printing on appropriate media.
A form of protection is recommended
to prevent damage which could render
the poster illegible. Conditions to avoid
include moisture infiltration, fading,
mutilation, etc.. Protective measures
may include lamination, placement
within an impact- and water-resistant
frame, etc.
The format shown in this document is
landscape orientation on US Tabloid
size, also known as ANSI B drawing
format, both roughly comparable to
ISO A3 size format.
To avoid potential cropping of content
when printing to A3 format, select
options such as print to fit or scale
to fit. Depending on printer capabil-
ity content will be slightly reduced but
should remain readable.
