General
Description
The TYCO DV-5aAutomatic Water
Control Valves are diaphragm type
valves that can be used in Preac-
tion Type A Fire Protection Systems
(EN12845). When properly trimmed, the
double seat design of the DV-5aValve
also provides actuation of re alarms
upon system operation.
Preaction Type A Fire Protection
Systems are characterized in normal
operation as being a single interlock
system wherein upon electric fire
detection the system piping is ooded
before sprinkler operation. Flooding of
the system converts the normally dry
pipe system into a water lled system
ready for sprinkler operation. The Pre-
action Type A Fire Protection Systems
are further characterized when being in
a fault detection, as in a loss of primary
and back-up battery electric power, as
converting to a dry pipe system. In dry
system mode, opening of a sprinkler
results in loss of system air pressure
and opening the DV-5aValve.
The diaphragm style design of the
DV-5aValve allows external resetting,
providing for easy resetting of the Pre-
acton Type A System without having to
open a valve handhole cover to manu-
ally 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-5aValves are offered with the
DV-5aValve and separately ordered
semi-assembled trim shown in Figure
5, or, for ease of installation, with the
DV-5aValve completely trimmed.
Preaction Type A Systems utilize auto-
matic sprinklers and a supplemental
detection system. The supplemental
detection system is typically comprised
of 24 VDC heat detectors, smoke
detectors, and manual pull stations.

DV-5AVALVE OPERATION, PREACTION TYPE A SYSTEMS

TFP1485
Page 4 of 20
matically operates (releases) the DV-5a
Valve, allowing water to ow into the
sprinkler piping system and to be dis-
charged from any sprinklers that may
subsequently open. In the event of loss
of power, the DV-5aValve with Preac-
tion Type A Trim will act as a regular
dry-pipe valve system.
The DV-5aValve with Preaction Type
A Trim has been designed in accor-
dance with the EN12845. This standard
denes operation as a dry pipe system
principally activated by an automatic
re detection system rather than the
operation of sprinklers.
Typically, the system designer selects
detection components electrically
operated that will respond to a re
sooner than the automatic sprin-
klers. Consequently, the system will
experience a minimal delay in water
delivery over that for a wet pipe sprin-
kler system because the system will
have begun to ll with water before a
sprinkler operates. Preaction Type A
Systems are typically designed as wet
pipe systems or according to the local
authority having jurisdiction.
The DV-5aValve with Preaction Type
A Trim is generally used to protect
areas where there is danger of serious
water damage that might result from
damaged automatic sprinklers or
piping. Typically, such areas include
computer rooms, storage areas
for valuable artifacts, libraries, and
archives.
These systems are also effectively used
to protect properties where a pre-alarm
of a possible re condition may allow
time for re extinguishment by alternate
suppression means, prior to a sprinkler
discharge. In the event the re cannot
otherwise be extinguished, the preac-
tion sprinkler system will then perform
as the primary re protection system.
NOTICE
The DV-5aValve with Preaction Type A
Trim described herein must be installed
and maintained in compliance with this
document, as well as with the EN12845
installation standard, in addition to
the standards of any other authorities
having jurisdiction. Failure to do so may
impair the performance of the related
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.

Detection System
In order for DV-5aValves with Preac-
tion Type A Trim to be hydraulically
calculated as a wet pipe system, the
detection system must be designed
to operate sooner than the automatic
sprinklers on the sprinkler piping.
The DV-5aValve with Preaction Type A
Trim provides for electric operation of
the DV-5aValve by a detection system
consisting of electrical devices such
as heat sensitive thermostats, smoke
detectors, and/or manual pull stations.
Nominal installation dimensions for the
Preaction Type A Trim conguration are
shown in Figure 7.
NOTICE
The one each normally closed and
normally open, de-energized Sole-
noid Valves are separately ordered
and selected based on the required
laboratory approval acceptable to the
authority having jurisdiction. Refer to
Technical data Sheet TFP2180 for spe-
cific laboratory approvals. Consult with
the authority having jurisdiction regard-
ing installation criteria pertaining to
electric actuation circuitry.
System Air Pressure
Requirements
The DV-5aValve with Preaction Type
A Trim includes a Model DP-1 Dry
Pilot Actuator. In a fault detection - for
example, loss of primary and back-up
battery electric power - the DP-1 can
actuate the DV-5aupon sprinkler oper-
ation and resulting loss of system air
(or nitrogen) pressure. For more infor-
mation, refer to Technical Data Sheet
TFP1380.
The air (or nitrogen) pressure in the
sprinkler system is recommended to
be automatically maintained using one
of the following pressure maintenance
devices, as appropriate:
• An air supply in combination with
Model AMD-1 Air Maintenance
Device (pressure-reducing type)
described in Technical Data Sheet
(TDS) TFP1221.
• An air supply in combination with
Model AMD-2 Air Maintenance
Device (compressor-control type)
described in TDS TFP1231
• A nitrogen cylinder in combination
with Model AMD-3 Nitrogen Mainte-
nance Device (high pressure-reduc-
ing type) described in TDS TFP1241
See Graph B for the minimum system
air pressure.
The Supervisory Low Pressure
Alarm Switch is typically eld set at
0,4 bar below the minimum system air
pressure.
The Pressure Relief Valve is factory set
to fully open at 44.96 psi (3,1 bar) plus
or minus 2.03 (0,14 bar).

Operation
The TYCO DV-5aValve is a diaphragm
style valve that depends upon water
pressure in the Diaphragm Chamber
as shown in 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 an actuation device (solenoid
valve or dry pilot actuator) 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 the
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 reduced below the
valve trip point. The water supply pres-
sure then forces the Diaphragm open
permitting water to ow into the system
piping, as well as through the Alarm
Port to actuate the system alarms as
shown in Figure 2B.
In normal operation, the system air
pressure is monitored by a Super-
visory Low Pressure Alarm Switch.
Should damage occur to a sprinkler or
the system piping, loss of air pressure
will not result in opening of the DV-5a
Valve and ooding of the system with
resulting inadvertent water discharge.
Loss of system air pressure will only
result in a low air alarm so that repairs
to the system can be facilitated to avoid
unnecessary water damage should the
system be activated in the event of a
re.
However, in the event of a re, opera-
tion of an electrical detection device
such as a heat-sensitive thermostat
or smoke detector signals the deluge
valve releasing panel to energize the
normally closed Solenoid Valve. In
turn, the energized Solenoid Valve
opens to release water from the Dia-
phragm Chamber faster than it can be
replenished through the restriction pro-
vided in the diaphragm supply connec-
tion. This release of water results in a
rapid pressure drop in the Diaphragm
Chamber to below the valve trip point.
The water supply pressure then forces

the Diaphragm open, permitting water
to ow into the system piping, as well
as through the Alarm Port to actuate
the system alarms.
In the event of a fault detection in the
re detection system, the system con-
verts to operate as an ordinary dry pipe
system, which means the energized-to-
close Solenoid Valve in the actuation
loop becomes de-energized and open
to communicate any system air pres-
sure loss to the DP-1 Dry Pilot Actu-
ator. As soon as a sprinkler operates/
activates, the subsequent drop in air
pressure opens the Dry Pilot Actuator.
Water from the diaphragm pressure
piping will exit the Dry Pilot Actuator
through this drain, resulting in the acti-
vation of the DV-5aDeluge Valve.
Upon opening of the DV-5aValve,
whether by Solenoid Valve or Dry Pilot
Actuator, the Model MRA-1 Manual
Reset Actuator opens to constantly
vent the DV-5aDiaphragm Chamber
to hydraulically latch the DV-5ain the
tripped position until manually reset.
For more information on the TYCO
Model MRA-1 Manual Reset Actuator,
refer to Technical Data Sheet TFP1387.
Due to the functionality of the Model
MRA-1 Manual Reset Actuator, the
release circuit of the releasing panel
need only provide the typical ten
minutes of alarm condition intended
to energize the Solenoid Valve to
open. After the ten minute duration, at
which point should the Solenoid Valve
become de-energized and close (espe-
cially while operating under battery
back-up), the MRA-1 will have already
automatically opened, thereby prevent-
ing the DV-5a Diaphragm Chamber
from becoming re-pressurized, and
preventing an inadvertent closing of
the DV-5a during a re event.
Installation
The TYCO DV-5aValve with Preaction
Type A Trim is to be installed in accor-
dance 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-5aValve
depends upon its 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-5aValve from func-
tioning properly, as well as void approv-
als and the manufacturer’s warranties.
The DV-5aValve must be installed in a
readily visible and accessible location.
The DV-5aValve and associated trim
must be maintained at a minimum tem-
perature 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, ttings, 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-5aValve must be
trimmed in accordance with 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
ordered electronically supervised nor-
mally open valve.
Step 3. Care must be taken to ensure
that check valves, strainers, globe
valves, etc. are installed with the ow
arrows in the proper direction.
Step 4. Drain tubing to the Drip Funnel
must be installed with smooth bends
that will not restrict ow.
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 as shown in
Figure 8.
Step 8. Provisions must be made for
installation of an Inspector's Test Con-
nection (ITC) at the most hydraulically
demanding location of the sprinkler
system. The maximum orice size of
the ITC is to be no greater than the
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 applications
where the dew point must be maintained below -29°C. Refer
to Technical Data Sheet TFP1241.

smallest orice sprinkler installed in
the system.
Step 9. An Air Maintenance Device,
as described in the Technical Data
section, must be provided for air supply
connection.
Step 10. A desiccant dryer, when spec-
ied, is to be installed between a drip
leg and the Air Maintenance Device.
Step 11. The Supervisory Low Pres-
sure Alarm Switch is to be adjusted to
provide a low air alarm at approximately
0,4 bar below the system air pressure
requirement shown in Graph B.
Step 12. Unused Pressure Alarm
Switch connections must be plugged.
Step 13. The Pressure Relief Valve pro-
vided with the Preaction Type A Trim is
factory set to relieve at a pressure of
approximately 3,1 bar, which can typi-
cally be used for a maximum system
pressure of 2,8 bar. The Pressure Relief
Valve may be reset; however, it must be
reset to relieve at a pressure which is
in accordance with the requirements of
the authority having jurisdiction.
To reset the Pressure Relief Valve, rst
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 ver-
ifying the desired pressure setting,
tighten the jam nut.
Step 14. Conduit and electrical con-
nections are to be made in accordance
with the applicable standards of the
approval agency.
Step 15. 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 specications.
Valve Setting
Procedure
Perform Steps 1 through 16 when ini-
tially setting the TYCO DV-5aValve with
Preaction Type A Trim, after an opera-
tional test of the re protection system,
or after system operation due to a re.
The valve with trim is shown in Figure 8.
Step 1. Close the System Main Control
Valve (B).
Step 2. Close the Diaphragm Supply
Valve (P). Close the Air Supply Control
Valves (X) and (Y).
Step 3. Open the Main Drain Valve (D),
System Drain Valve (E), and all auxil-
iary drains in the system. Also, remove
the plug from the Air Supply Strainer
(W) to drain any water that is present
and to ensure the it is clean and free of
debris. Close the auxiliary drain valves,
System Drain Valve (E), and reassemble
the Air Supply Strainer (W) after water
ceases to discharge. Leave the Main
Drain Valve (D) open.
At this time make certain that the
Pressure Gauge Valves and the Alarm
Control Valve (H), as applicable, are
open.
Step 4. Depress the plunger of the
Automatic Drain Valve (F) to verify that
it is open.
Step 5. Clean the Diaphragm Supply
Strainer (Q) by removing the clean-
out plug and strainer basket. The Dia-
phragm Supply Strainer (Q) may be
ushed out by momentarily opening
the Diaphragm Supply Valve (P).
Step 6. Replace operated automatic
sprinklers on the system piping.
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 7. Reset the DV-5aValve Releas-
ing Panel in accordance with the manu-
facturer instructions.
Step 8. Re-establish system air pres-
sure to reset the Model DP-1 Dry Pilot
Actuator (T) by opening the Air Supply
Control Valve (X). Do not open the Air
Supply Control Valve (Y) at this time.
The Dry Pilot Actuator (T) air pressure
will be indicated on the Dry Pilot Gauge
(Z).
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 10. After allowing water to ow
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 owing
from its drain tube and the pressure
builds and reaches approximately 15
psi (1,0 bar) on the Diaphragm Gauge
(K). Pressure will then build up in the
DV-5aDiaphragm Chamber.
Step 11. Verify the ability for the DV-5a
Diaphragm to hold pressure as follows:
• With the diaphragm chamber
pressurized per Step 10, tempo-
rarily 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 Air Supply Control
Valve (Y) to pressurize the system
piping. The system air pressure will be
indicated on the System Gauge (L).
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 the valve trim maximum pressure
rating provided in the Technical Data
section, the pressure is to be relieved
to at least the valve trim pressure rating
by partially and temporarily 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.
Step 14. Close the hinged cover on 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 re 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 specic requirements
of EN12845. Any impairment must be
immediately corrected. The DV-5a
valve and trim assembly is shown in
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
(AA). 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
EN12845.
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.
Some of the procedures outlined in
this section will result in operation of
the associated alarms. Consequently,
notification must first be given to the
owner and the fire department, central
station, or other signal station to which
the alarms are connected.
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 applicable stan-
dards of EN12845 in addition to the
standards of any authority having juris-
diction. Contact the installing contrac-
tor 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 local
requirements and/or national codes.
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
valve such as the DV-5acould inadver-
tently 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 main control valve and
use the following procedure 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 pres-
sure 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 waterow alarm, open the
Alarm Test Valve (G), which will allow a
ow of water to the Waterow 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).

• After system pressure is restored
in the DV-5A Diaphragm Chamber,
inspect the Solenoid Valve (R) and
Manual Reset Actuator (N) for leaks
at the drain tube. 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).
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.
Solenoid Valve and
Dry Pilot Actuator Test Procedure

Proper operation of the Supervisory
Low Pressure Alarm Switch and vali-
dation of the normally closed Solenoid
Valve (S) must be performed as follows:
Step 1. Close the System Main Control
Valve (B).
Step 2. Open the Main Drain Valve (D).
Step 3. Crack open the system's
Inspector's Test Connection to relieve
air pressure from the system. Verify that
the Supervisory Low Pressure Alarm
Switch (V) is operational and that the
low pressure set point is approximately
0,4 bar under the minimum system air
pressure.
Step 4. Allow the system air pressure
to decay to 0 psig (1,01 bar). Verify that
there is no water draining from the Dry
Pilot Actuator (T), as will be the case if
the Solenoid Valve (S) is in the normally
closed position.
Step 5. Close the system's Inspector's
Test Connection and allow the system
supervisory pressure to be automati-
cally re-established. As necessary,
open and then close the quick ll air
supply control valve in the automatic air

DV-5aValve is ready to be placed in
service and the System Main Control
Valve (B) must then be fully opened.
Operation Test Procedure
Proper operation of the DV-5aValve
with Preaction Type A Trim (i.e., opening
of the DV-5aValve as during a re con-
dition) must be veried at least once a
year as follows:
If water must be prevented from owing
beyond the riser, perform the following
steps:
• Close the System Main Control Valve
(B).
• Open the Main Drain Valve(D).
• Open the System Main Control Valve
(B) one turn beyond the position at
which water just begins to ow from
the Main Drain Valve (D).
• Close the Main Drain Valve (D).
Step 1. Test the deluge releasing panel
in accordance with the manufacturer’s
instructions to energize the Solenoid
Valve (R).
NOTICE
Be prepared to perform Steps 2, 3, and
4 quickly if water must be prevented
from flowing beyond the riser.
Step 2. Verify that the DV-5aValve has
tripped, as indicated by the ow of
water into the system.
Step 3. Close the System Main Control
Valve (B).
Step 4. Close the Diaphragm Supply
Valve (P) and the Air Supply Control
Valves (X) and (Y).
Step 5. Reset the DV-5aValve with Pre-
action Type A Trim in accordance with
the Valve Setting Procedure.
Internal Valve Inspection
Once every ve 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).
When reinstalling the Diaphragm Cover,
complete the following steps to assure
the Diaphragm Cover Fasteners are
uniformly and securely tightened.
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 (AA).
Step 2. Remove the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (AA).
Step 3. Disconnect the conduit from
the Solenoid Valve (S).
Step 4. Loosen the nut securing the
copper piping to the tee connection
below the Air Supply Control Valve “B”
(Y).
Step 5. Remove the nut from the tting
located at the Air Supply Strainer (W).
Step 6. Loosen the union below the
Dry Pilot Actuator and below the Dia-
phragm Gauge (K).

TFP1485
Page 16 of 20
Step 7. Disassemble the union between
the Diaphragm Cover and the MRA-1
Manual Reset Actuator (N) and remove
the assembly.
Step 8. Remove the Diaphragm Valve
Cover hardware, then slowly remove
the Diaphragm Cover and perform
internal valve inspection. Clean the
valve interior 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. Ensure that the Diaphragm is
properly oriented as shown in Figure 1,
and that the proper hardware arrange-
ment is utilized when assembling the
Diaphragm Covers. The hardware
arrangements differ depending on the
size of the DV-5A Valve.
Step 2. By rst using the Long Hex
Bolts, support of the Diaphragm Cover
will be provided before installing the
Short Hex Bolts. Align Diaphragm in
proper orientation with Valve Body, and
then align Diaphragm Cover in proper
orientation 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 appropriate torque values. Repeat
crossdraw sequence two to three
times at incremental torque valves
until reaching the torque valves found
in Table B.
Step 4. Inspect to assure all Hex Bolts
are securely tightened.
Step 5. Secure the assembly by reas-
sembling the union between the MRA-1
Manual Reset Actuator (N) to the Dia-
phragm Cover.
Step 6. Align the copper piping below
the Air Supply Strainer (W) and replace
the nut. Then tighten the nut located
below the Air Supply Control Valve “B”
(Y).
Step 7. Connect the conduit to the
Solenoid Valve (S).
Step 8. Replace the Copper Tube
Fitting between the Diaphragm Supply
Valve and the Inverted Flare Shut-Off
Valve (AA).
Step 9. Ensure that the unions and are
ttings are securely tightened.
Step 10. With the Diaphragm Supply
Valve (P) closed, fully open the Inverted
Flare Shut-Off Valve (AA) stainless
steel screw (approximately ½ in.) until
resistance 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 (AA) stainless steel
screw.
Step 11. Proceed to 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 fabric-
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 inspection 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
