Tyco DV-2 User manual

General
Description
The 2 inch (DN50) Model DV-2 Deluge
Valve is a quick opening, hydraulically
operated differential type valve de-
signed for fire protection system serv-
ice. It is used as an “automatic water
control valve” in deluge, preaction, and
special types of fire protection sys-
tems. The Model DV-2 Deluge Valve
also provides for actuation of fire
alarms upon system operation.
Operation of the DV-2 Valve is pro-
vided by an actuation (detection) sys-
tem that is separate from the normally
dry system piping. Trim configuration
options for automatic operation of the
DV-2 include wet pilot actuation, dry
pilot actuation, and electric actuation.
Trim arrangements also provide for lo-
cal emergency (manual) release of the
Model DV-2 Deluge Valve.
The Model DV-2 Deluge Valve is a re-
designation for the Gem Model B
Flooding Valve and Star Model B Del-
uge Valve.
WARNING
The Model DV-2 Deluge Valve de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the applica-
ble standards of the National Fire Pro-
tection Association, in addition to the
standards of any other authorities hav-
ing jurisdiction. Failure to do so may
impair the integrity of this device.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.

Wet Pilot
Actuation
(Basic Trim plus Alarm & Test
Trim)
Wet Pilot Actuation provides for con-
nection of a detection system consist-
ing of pilot sprinklers (heat detectors)
and manual control stations intercon-
nected with minimum 1/2 inch (DN15)
Schedule 40 steel pipe. The pilot line
is connected to the “Connection For
Following Releasing Devices:” shown
in Figure 2.
Pilot sprinklers are to be minimum 1/2
inch (15 mm) orifice listed or approved
automatic sprinklers, and remote man-
ual pull stations, where required, are to
be Model MC-1 Manual Control Sta-
tions.
The maximum height of a wet pilot line
above the Model DV-2 Deluge Valve
must not exceed the limitations given
in Graph A as a function of the mini-
mum water supply pressure to the
Model DV-2 Deluge Valve and the
length of the pilot line to the most re-
mote pilot sprinkler.
Provision must be made for installing
a 1/2 inch (DN15) orifice Inspector’s
Test Connection at the most hydrauli-
cally demanding location of a wet pilot
line (usually adjacent to the highest
and most remote wet pilot sprinkler or
manual control station).
Operation of a pilot sprinkler or open-
ing of a manual control station results
in a rapid pressure drop in the Upper

Dry Pilot
Actuation
(Basic Trim plus Alarm & Test
Trim plus Dry Pilot Actuation Trim)
Dry Pilot Actuation provides for instal-
lation of a detection system consisting
of pilot sprinklers (heat detectors) and
manual control stations intercon-
nected with minimum 1/2 inch (DN15)
steel pipe. The pilot line, which is to be
pressurized with air or nitrogen, is con-
nected to the “Dry Pilot Line Connec-
tion” shown in Figure 5. Provision must
be made for a 1/2 inch (15 mm) orifice,
Inspector’s Test Connection at the
most remote location from the Model
DV-2 Deluge Valve.
The Dry Pilot Actuation Trim is pro-
vided with a listed and approved Model
DP-1 Dry Pilot Actuator. The Actuator
is rated for use at a maximum pilot
service pressure of 50 psi (3,4 bar)
and a maximum water supply service
pressure of 175 psi (12,1 bar).
Operation of a pilot sprinkler or open-
ing of a manual control station re-
leases pneumatic pressure from the
pilot line. In turn, the Dry Pilot Actuator
opens, resulting in a rapid pressure

drop in the Upper Chamber of the
Model DV-2 Deluge Valve, and the
force differential holding the Model
DV-2 Deluge Valve in the set position
is eliminated.
Dry pilot sprinklers are to be minimum
1/2 inch (15 mm) orifice listed or ap-
proved automatic sprinklers, and re-
mote manual pull stations, where re-
quired, are to be Model MC-1 Manual
Control Stations.
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.
•Model AMD-1 Air Maintenance De-
vice (pressure reducing type), refer
to Technical Data Sheet TFP1221.
•Model AMD-2 Air Maintenance De-
vice (compressor control type), refer
to Technical Data Sheet TFP1231.
•Model AMD-3 Nitrogen Mainte-
nance Device (high pressure reduc-
ing type), refer to Technical Data
Sheet TFP1241.
NOTES
The dewpoint of the pilot line air pres-
sure 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 pre-
vent proper operation. Also, introduc-
tion of moisture into the pilot lines ex-
posed to freezing temperatures can
create an ice buildup which could pre-
vent 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 Ni-
trogen Maintenance Device be utilized
in dry pilot actuation system applica-
tions where the dewpoint must be
maintained below -20°F/-29°C. See
Technical Data Sheet TFP1241.
It is recommended that internally gal-
vanized pipe and cast iron fittings be
used for dry pilot lines.
Supervision of the pressure in the dry
pilot actuation system and/or alarm
that separately indicates operation of
the detection system is recommended
and may be required by the authority
having jurisdiction. A dual setting low
pressure alarm switch, such as the
Potter Electric PS40-2A, is suitable for
the service. The recommended pres-
sure settings are as follows:
•Low pressure alarm setting at ap-
proximately 6 psi (0,4 bar) below the
minimum pilot line service pressure
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 Pressure Relief Valve (Ref. Item 4
- Fig. 5 ) 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.
Electric
Actuation
(Basic Trim plus Alarm & Test
Trim plus Electric Actuation Trim)
Electric Actuation is required for elec-
tric operation of the Model DV-2 Del-
uge Valve by a detection system con-
sisting of electrical devices such as
heat sensitive thermostats, smoke de-
tectors, and/or electric manual pull sta-
tions. Information on the various types
of separately ordered Solenoid Valves
that may be used with the Electric Ac-
tuation Trim is given in Technical Data
Sheet TFP2180.
NOTE
Approval by Factory Mutual is contin-
gent on the use of an FM Approved
24VDC Solenoid Valve. FM only ap-
proves solenoid valves for use in non-
hazardous locations.
The Electric Actuation Trim is only to
be used in conjunction with an electric
deluge valve releasing panel (auto-
matic control unit) that is listed or ap-
proved (as appropriate) for fire protec-
tion system releasing service. In
addition, the deluge valve releasing
panel is only to be operated by listed
or approved (as appropriate) fire de-
tectors.
Operation of an electrical device such
as heat sensitive thermostat, smoke
detector, or electric manual pull station
signals the deluge valve releasing
panel to energize the Solenoid Valve.
In turn, the energized Solenoid Valve
opens resulting in a rapid pressure
drop in the Upper Chamber of the
Model DV-2 Deluge Valve, and the
force differential holding the Model
DV-2 Deluge Valve in the set position
is eliminated.
NOTE
Consult with the Authority Having Ju-
risdiction regarding installation criteria
pertaining to electric actuation cir-
cuitry.
Operating
Principles
The Model DV-2 Deluge Valve is a dif-
ferential valve that depends upon
water pressure in the Upper Chamber
to hold the Center Valve Assembly
closed against the water supply pres-
sure. The nominal trip ratio is 2.5 to 1,
i.e., the Model DV-2 Deluge Valve op-
erates (opens) when the pressure in
the Upper Chamber is reduced to ap-
proximately 40 percent of the water
supply pressure.
When the Model DV-2 Deluge Valve is
set for service, the Upper Chamber is
pressurized through the trim connec-
tions from the inlet side of the system’s
main control valve (Fig. 2). Opening of
an actuation device, for example the
solenoid valve in the Electric Actuation
Trim (Fig. 6), releases water from the
Upper Chamber faster than it can be
replenished through the 1/8" (3,2 mm)
Restriction in the Upper Chamber Sup-
ply Connection (Item 8 - Fig. 2). This
results in a rapid pressure drop in the
Upper Chamber and the force differen-
tial holding the Center Valve Assembly
down in the set position is eliminated.
The water supply pressure then forces
the Center Valve Assembly open, per-
mitting water to flow into the system
piping, as well as through the Alarm &
Test Trim (Fig. 4) to actuate system
alarms.

Installation
NOTES
Proper operation of the Model DV-2
Deluge Valve depends upon its trim
being installed in accordance with the
instructions given in this Technical
Data Sheet. Failure to follow the ap-
propriate trim diagram may prevent
the Model DV-2 Deluge Valve from
functioning properly, as well as void
listings, approvals, and the manufac-
turer’s warranties.
The Model DV-2 Deluge Valve must be
installed in a readily visible and acces-
sible location.
The Model DV-2 Deluge Valve, asso-
ciated trim, and wet pilot lines must be
maintained at a minimum temperature
of 40°F/4°C.
Heat tracing of the Model DV-2 Deluge
Valve or its associated trim is not per-
mitted. Heat tracing can result in the
formation of hardened mineral depos-
its which are capable of preventing
proper operation.
The Model DV-2 Deluge Valve is to be
installed in accordance with the follow-
ing criteria:
Step 1. All nipples, fittings, and de-
vices must be clean and free of scale
and burrs before installation. Use pipe
thread sealant sparingly on male pipe
threads only.
NOTE
It is recommended that internally gal-
vanized pipe and cast iron fittings be
used for wet or dry pilot lines.
Step 2. Refer to Figure 3 for installa-
tion of either the 2 or 2-1/2 inch Dis-
charge Trim, as applicable. If a 1-1/2
inch discharge is required, the 1-1/2
inch outlet connection on the right
hand side of the Model DV-2 Deluge
Valve must be plugged.
Step 3. The Model DV-2 Deluge Valve
must be trimmed in accordance with
Figures 2 and 4, as well as Figures 5
and 6 as applicable. The Basic Trim
has been designed to facilitate use of
a gate valve having an end-to-end di-
mension of 3-7/8 inches. If another
type of main control valve is to be
used, the connection to the Upper
Chamber Supply Control Valve may be
modified accordingly.
Step 4. Care must be taken to make
sure that check valves, strainers,
globe valves, etc. are installed with the
flow arrows in the proper direction.
Step 5. Drain tubing to the drip funnel
must be installed with smooth bends
that will not restrict flow.
Step 6. The main drain and flow test
drain may be interconnected to the
drip funnel drain provided a check
valve is located at least 12 inches (300
mm) below the drip funnel.
Step 7. Suitable provision must be
made for disposal of drain water.
Drainage water must be directed such
that it will not cause accidental dam-
age to property or danger to persons.
Step 8. An Inspector’s Test Connec-
tion, as described in the Wet Pilot Ac-
tuation or Dry Pilot Actuation section,
must be provided for Wet or Dry Pilot
Actuation.
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 ap-
proximately 6 psi (0,4 bar) below the
minimum pilot line service pressure
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 13. The Pressure Relief Valve
provided with the Dry Pilot Actuation
Trim is factory set to relieve at a pres-
sure of approximately 45 psi (3,1 bar),
which can typically be used for a maxi-
mum normal dry pilot actuation system
pressure of 40 psi (2,8 bar). The Pres-
sure Relief Valve may be reset; how-
ever, it must be be reset to relieve at a
pressure that is in accordance with the
requirements of the authority having
jurisdiction.
To reset the 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. Conduit and electrical con-
nections are to be made in accordance
with the requirements of the authority
having jurisdiction and/or the National
Electric Code.

Step 4. Depress the plunger of the
Automatic Drain Valve (Fig. 2) to verify
that it is open and that the Model DV-2
Deluge Valve is completely drained.
Step 5. Clean the Strainer (Fig. 2) in
the Upper Chamber Supply Connec-
tion by removing the clean-out plug
and strainer basket. The Strainer may
be flushed by momentarily opening the
Upper Chamber Supply Control Valve.
Step 6. Open the Alarm Control Valve
(Fig. 4) if it was closed to silence local
alarms.
It is recommended that the Alarm Con-
trol Valve be wire sealed in the open
position with a No. 16 twisted wire, the
ends of which are secured by a lead
seal. The wire seal should be looped
through the hole in the handle and
tightly twisted around the pipe nipple
adjacent to the handle.
Step 7. Reset the actuation system.
Manual Actuation — Reset the Manual
Control Station (Fig. 2); however, do
not close the hinged cover at this time.
Wet Pilot Actuation — Replace oper-
ated pilot sprinklers and/or reset the
manual control stations.
Dry Pilot Actuation — Replace oper-
ated pilot sprinklers and/or reset the
manual control stations. Re-establish
dry pilot pneumatic pressure.
Electric Actuation — Reset the electric
detection system in accordance with
the manufacturer’s instructions to de-
energize the solenoid valve.
NOTE
In order to prevent the possibility of a
subsequent operation of an over-
heated solder type sprinkler, any sol-
der type sprinklers that were possibly
exposed to a temperature greater than
their maximum rated ambient must be
replaced.
Step 8. Remove the Cover from the
Model DV-2 Deluge Valve, and then
remove the Center Valve Assembly.
Thoroughly clean and inspect the Cen-
ter Valve Assembly for wear or dam-
age, as well as all interior surfaces of
the Valve Body and Cover. Special
consideration should be given to the
condition of the Diaphragm and Fac-
ing. The Diaphragm and/or Facing
should be replaced if there are any
sign of deterioration due to age or
chemicals in the water. If the water
supply contains chemicals which tend
to attack an EPDM type rubber, then
the frequency of the Diaphragm and
facing inspection should be increased
to at least annually.
Worn or damaged parts must be re-
placed and the Model DV-2 Deluge
Valve must be reassembled in accord-
ance with Figure 1. The Cap Screws
securing the Cover should be uni-
formly tightened using a cross-draw
sequence.
Step 9. Open the Upper Chamber
Supply Control Valve (Fig. 2) and allow
time for full pressure to build up in the
Upper Chamber.
Step 10. Operate (open) the Manual
Control Station (Fig. 2) to vent trapped
air from the Upper Chamber. If neces-
sary, first open the hinged cover, and
then fully pull down on the operating
lever. SLOWLY close the operating
lever, by pushing it up after aerated
water ceases to discharge from the
Manual Control Station drain tubing.
Close the hinged cover and insert a
new break rod in the small hole
through the top of the enclosing box.
If wet pilot actuation is being used,
crack open the Inspector’s Test Con-
nection and any other vent valves, to
relieve trapped air. After the discharge
of air has stopped, close the vent
valves and the Inspector’s Test Con-
nection.
Step 11. Inspect drain connections
from the Manual Control Station, Sole-
noid Valve, Dry Pilot Actuator, and
Alarm Devices, as applicable. Any
leaks must be corrected before pro-
ceeding to the next step.
Step 12. Slowly open the Main Control
Valve. Close the Flow Test Valve (Fig.
2) as soon as water discharges from
the Flow Test Valve. Observe the Auto-
matic Drain Valve (Fig. 2) for leaks. If
there are leaks, determine/correct the
cause of the leakage problem. If there
are no leaks, the Model DV-2 Deluge
Valve is ready to be placed in service
and the Main Control Valve must then
be fully opened.
NOTE
After setting a fire protection system,
notify the proper authorities and ad-
vise 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 impair-
ment must be immediately corrected.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of any authorities having ju-
risdiction. The installing contractor or
product manufacture should be con-
tacted relative to any questions.
It is also recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
NOTES
Some of the procedures outlined in
this section will result in operation of
the associated alarms. Consequently,
notification must be given to the owner
and the fire department, central sta-
tion, or other signal station to which the
alarms are connected.
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 decision must be
notified.
Drop In Water Supply Pressure Be-
low Normal Range
NOTE
If the water supply pressure is signifi-
cantly reduced below the normally ex-
pected static pressure range (as could
occur in the case of a water main break
or repair), and there is a subsequent
drop in the upper chamber water pres-
sure below its normal range (due, for
example, to a leak in a piping connec-
tion to or from the upper chamber or, a
leak in the upper chamber check valve
caused by dirt or debris in the check
valve seal area), a deluge valve such
as the Model DV-2 could inadvertently
Page8of12 TFP1340
OBSOLETE

trip if its water supply pressure is
quickly restored.
A drop in the water supply pressure
below its normal range (as in the case
of an interrupted water supply condi-
tion) constitutes an emergency impair-
ment as defined by NFPA 25. Should
this condition occur, immediately
close the main control valve and util-
ize the following procedure to reset the
system:
Step 1. Prior to the water supply pres-
sure being restored to the closed main
control valve, note the pressure indi-
cated by the upper chamber pressure
gauge and, whether the pressure is
within the normally expected range.
Step 2. If the upper chamber pressure
is below the normal range, check for
and correct any source of leakage
from the upper chamber, prior to reset-
ting the system.
Step 3. After the water supply pres-
sure is restored to the main control
valve, reset the Model DV-2 Deluge
ValveinaccordancewiththeValve
Setting Procedure section.
NOTE
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 sup-
ply pressure switch, with the appropri-
ate alarm/indications, to monitor the
water supply pressure
Annual Operation Test Procedure
Proper operation of the DV-2 Valve
(i.e., opening of the DV-2 Valve as dur-
ing a fire condition) must be verified at
