General
Description
The 4 and 6 inch (DN100 and DN150),
Model DV-1 External Resetting Del-
uge Valves are differential latch type
valves designed for fireprotection sys-
tem service. They are used as “auto-
matic water control valves” in deluge,
preaction,andspecialtypesof firepro-
tection systems such as foam-water
and double interlock. The DV-1 Valves
alsoprovideforactuationof firealarms
upon system operation.
The external resetting feature of the
DV-1 Valve provides for easyresetting
of a deluge or preaction system, with-
out having to open a valve handhole
cover to manually reposition a clapper
and latch mechanism. Simply de-
pressing a plunger at the left side of
the DV-1 Valve allows the clapper and
latch to reset.
Operation of a DV-1 Valve is provided
byanactuation(detection)systemthat
is separate from the normally dry sys-
tem piping. Trim configuration options
for automatic operation of the DV-1
include wet pilot actuation, dry pilot
actuation, and electric actuation. Trim
arrangements also provide for local
emergency (manual) release of the
DV-1 Valves.
WARNING
The Model DV-1 Deluge Valves 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 ofany other authorities hav-
ing jurisdiction. Failure to do so may
impair the integrity of these devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or manufac-
turer should be contacted relative to
any questions.

Valve Trim
The Wet Pilot Actuation Trim, Dry Pilot
Actuation Trim, and Electric Actuation
Trim form a part of the laboratory list-
ings and approval of the DV-1 Valves
and are necessary for their proper op-
eration. Each package of trim includes
the following items:
•Water Supply Pressure Gauge
•Diaphragm Chamber
Pressure Gauge
•Diaphragm Chamber Connections
•Actuation Devices (as applicable)
•Main Drain Valve
•Alarm Test Valve
•Alarm Control Valve
•Automatic Drain Valve
•Dry Pilot Line Pressure Gauge
(as applicable)
To ease field assembly of the trim ar-
rangements, the appropriate compo-
nents required for Wet Pilot Actuation,
Dry Pilot Actuation, or Electric Actua-
tion are provided partially assembled
as shown in Figure 12.
Wet Pilot
Actuation
The Wet Pilot Actuation Trim provides
for connection of a detection system
consisting of wet pilot sprinklers (heat
detectors) and manual control stations
interconnected with minimum 1/2 inch
(DN15) Schedule 40 steel pipe. The
pilot line is connected to the “Wet Pilot
Detection” connection shown in Fig-
ures 4 and 12. Nominal installation di-
mensions for the Wet Pilot Actuation
Trim are shown in Figure 4.
Wet pilot sprinklers are to beminimum
5.6 K-factor orifice listed or approved
automatic sprinklers. Manual Control
Stations are to be the Model MC-1
described in Technical Data Sheet
TD1382.
The maximum height of a wet pilot line
abovetheDV-1Valvemustnotexceed
the limitations given in Graph B as a
function of the minimum water supply
pressure to the DV-1 Valve and the
length of the pilot line to the most re-
mote pilot sprinkler.
Provision must be made for installing
a 5.6 K-factor orifice, Inspector’s Test
Connection at the most hydraulically
demanding location of a wet pilot line
(usually adjacent to the highest and
mostremotewetpilotsprinklerorman-
ual control station).
To determine the most hydraulically
demanding location of a wet pilot line,
when the choice between two or more
locations is not readily apparent, de-
termine for each location the elevation
above the DV-1 Valve and the equiva-
lent length of fittings plus horizontal
pipe from the DV-1 Valve to the loca-
tion. Then, using Graph B, determine
the minimum system supply pressure
required for the elevation and equiva-
lent length of pipe at each location.
Interpolate between the equivalent
length plots as necessary. The loca-
tion requiring the highest system sup-
ply pressure is the most hydraulically
demanding location for the wet pilot
line. (Reference: In no case should the
required system supply pressure ex-
ceed the actual available minimum ex-
pected system supply pressure.)
Operation of a pilot sprinkler or open-
ing of a manual control station results
in a rapid pressure drop in the Dia-
phragm Chamber of the DV-1 Valve,
and the force differential applied
through the Clapper Latch which holds
the Clapper down in the set position is
reduced to below the valve trip point.
NOTES
Wet Pilot Lines must be maintained at
a minimum temperature of 40°F/4°C.
It is recommended that internally gal-
vanized pipe and cast iron fittings be
used for wet pilot lines.

Dry Pilot
Actuation
The Dry Pilot Actuation Trim provides
for installation of a detection system
consisting of dry pilot sprinklers (heat
detectors) and manual control stations
interconnected with minimum 1/2 inch
(DN15) steel pipe. The pilot line, which
is to be pressurized with air or nitro-
gen, is connected to the “Dry Pilot De-
tection” connection shown in Figures 7
and 12. Provision must be made for a
5.6 K-factor orifice, Inspector’s Test
Connection at the most remote loca-
tion from the DV-1 Valve. Nominal in-
stallation dimensions for Dry Pilot Ac-
tuation Trim are shown in Figure 7.
The Dry Pilot Actuation Trim is pro-
videdwithalistedand approvedModel
DP-1 Dry Pilot Actuator, which is de-
scribed in Technical Data Sheet
TFP1380.TheActuatorisratedforuse
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 Diaphragm Chamber of the
DV-1 Valve, and the force differential
applied through the Clapper Latch
which holds the Clapper down in the
set position is reduced to below the
valve trip point.
Dry pilot sprinklers are to be minimum
5.6 K-factor orifice listed or approved
automatic sprinklers. Manual Control
Stations are to be the Model MC-1
described in Technical Data Sheet
TFP1382.
Graph C 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 dew point 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
pilotlineconnectiontothe Actuatorwill
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 dew point 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
which separately indicates operation
of the detection system is recom-
mended and may be required by the
authority having jurisdiction. A dual
setting low pressure alarm switch,
such a PotterElectric PS40-2A,is suit-
able for the service. The recom-
mended pressure settings are as fol-
lows:
•Low pressure alarm setting at ap-
proximately 6 psi (0,4 bar) below the
minimum pilot line service pressure
requirement shown in Graph C.
•Fire alarm setting at approximately
15 psi (1,0 bar) below the minimum
pilot line service pressure require-
ment shown in Graph C.
The Pressure Relief Valve (Ref. Item
D6 - Fig. 6) is factory set to relieve at
apressureofapproximately45psi(3,1

Electric
Actuation
The Electric Actuation Trim is required
for electric operationof theDV-1 Valve
by a detection system consisting of
electrical devices such as heat sensi-
tive thermostats, smoke detectors,
and/or electric manual pull stations.
Information on the various types of
separately ordered Solenoid Valves
that may be used with this trim pack-
age is given in Technical Data Sheet
TFP2180. Nominal installation dimen-
sions for the Electric Actuation Trim
are shown in Figure 10.
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.
TheElectricActuationTrimisonlyto
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
panelisonlytobeoperatedbylisted
or approved (as appropriate) fire de-
tectors.
Operation of an electrical device such
as a heat sensitive thermostat, smoke
detector, or electrical manual control
station signals the deluge valve re-
leasing panel to energize the Solenoid
Valve. In turn, the energized Solenoid
Valve opens resulting in a rapid pres-
sure drop in the Diaphragm Chamber
of the DV-1 Valve, and the force differ-
ential applied through the Clapper
latch which holds the Clapper down in
theset positionis reducedtobelow the
valve trip point.
NOTE
Consult with the Authority Having Ju-
risdiction regarding installation criteria
pertaining to electric actuation cir-
cuitry.

Operating
Principles
The Model DV-1 Deluge Valve is a
differential latch type valve which de-
pends upon water pressure in the Dia-
phragm Chamber (Ref. Figure 11A) to
hold the Clapper closed against the
water supply pressure. The nominal
tripratio is2.5to 1,i.e.,theDV-1Valve
operates (opens) when thepressure in
the Diaphragm Chamber is reduced to
approximately 40 percent of the water
supply pressure.
WhentheDV-1Valveissetforservice,
the Diaphragm Chamber is pressur-
ized through the trim connections from
the inlet side of the system’s main con-
trolvalve,forexampleanO.S.&Y.gate
valve or butterfly valve (Ref. Figure 4,
7, and 10). Opening of an actuation
device, for example the solenoid valve
in the Electric Actuation Trim (Ref.Fig.
10), releases water from the Dia-
phragm Chamber faster than it can be
replenished through the 1/8 inch
(3,2mm) Restriction in the Diaphragm
Chamber Supply Connection. This re-
sults in a rapid pressure drop in the
Diaphragm Chamber and the force dif-
ferential applied through the Clapper
Latch to hold the Clapper down in the
set position is reduced to below the
valve trip point. The water supplypres-
sure then forces theClapper open per-
mitting water to flow into the system
piping, as well as through the Alarm
Port to actuate the system alarms
(Ref. Figure 11B).
When the system main control valve is
closed to stop waterflow into the sys-
tem, the Clapper will be prevented
from resetting by the Clapper Latch
until the Rest Knob is pushed inward
(Ref. Figures 11C and 11D). Pushing
the Reset Knob inward will temporarily
reposition the Clapper Latch away
from the waterway and allows the
Clapper to drop into the seated posi-
tion.

Installation
NOTES
Proper operation of the Model DV-1
DelugeValvesdependsupontheirtrim
being installed in accordance with the
instructions given in this Technical
Data Sheet. Failure to follow the ap-
propriate trim diagram may prevent
the DV-1 Valve from functioning prop-
erly,as wellas voidlistings,approvals,
and the manufacturer’s warranties.
The DV-1 Valve must be installed in a
readily visible and accessible location.
The DV-1 Valve, associated trim, and
wet pilot lines must be maintained at a
minimum temperature of 40°F/4°C.
Heat tracing of the DV-1 Valve or its
associated trim is not permitted. Heat
tracing can result in the formation of
hardened mineral deposits which are
capable of preventing proper opera-
tion.
The Model DV-1 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. The DV-1 Valve must be
trimmed in accordance with Figures 3
and 12.
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.

drain may be interconnected provided
a check valve is located at least 12
inches(300mm) below thedripfunnel.
Step 6. 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 7. Connect the Diaphragm
Chamber Supply Control Valve to the
inlet side of the system’s main control
valve in order to facilitate settingof the
DV-1Valve (Ref.Figures 4,7, and10).
Step 8. An Inspector’s Test Connec-
tion, as described in the Technical
Datasection,mustbeprovidedforWet
or Dry Pilot Actuation systems.
Step 9. An Air MaintenanceDevice,as
described in the Technical Data Sec-
tion, 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 C.
•Fire alarm setting at approximately
15 psi (1,0 bar) below the minimum
pilot line service pressure require-
ment shown in Graph C.
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 which is in accordance with
the requirements of the authority hav-
ing 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-
nectionsareto bemadein accordance
with the requirements of the authority
having jurisdiction and/or the National
Electric Code.
Step 15. Before a system hydrostatic
test is performed in accordance with
NFPA 13 system acceptance test re-
quirements, the Clapper Assembly is
to be manually latched open (Ref. Fig.
11D); the Automatic Drain Valve (Item
6, Fig. 3, 6, or 9) is to be temporarily
replaced with a 1/2 inch NPT plug, the
3/32 inch Vent Fitting (16 - Fig. 3, 6, or
9) is to be temporarily replaced with a
1/4 inch NPT plug, and the Handhole
Cover Bolts are to be tightened using
a cross-draw sequence.
Valve Setting
Procedure
Steps 1 through 11 are to be per-
formed when initially setting the Model
DV-1Deluge Valve; after an opera-
tional test of the fire protection system;
or, after system operation due to afire.
Step 1. Close the Diaphragm Cham-
ber Supply Control Valve.
Step 2. Close the Main Control Valve,
and if the system is equipped with Dry
Pilot Actuation, close the Air Supply
Control Valve (Ref. Fig. 12).
Step 3. Open the Main Drain Valve
and all auxiliary drains in the system.
Close the auxiliary drain valves after
water ceases to discharge. Leave the
Main Drain Valve open.
Step 4. Depress the plunger of the
Automatic Drain Valve to verify that it
is open and that the DV-1 Valve is
completely drained.
Step 5. Push the Reset Knob inward
to allow the Clapper to reseat.
Under normal circumstances, the re-
seating of the Clapper can be heard;
however, during an annual operation
test procedure, for example, due to
minimal flow through a partially
opened main control valve, the Clap-
per may not latch open as shown in
Figure 11C. In which case the reseat-
ing sound of the Clapper will not be
heard.
Also under normal circumstances,
water pressure in the riser will have
exerted sufficient force on the Dia-
phragm so as to have emptied most of
the water from the Diaphragm Cham-
ber which, in turn, will ease the push-
ing of the Reset Knob by eliminating
theresistive force producedby a water
filled Diaphragm Chamber. Therefore,
should water remain in the Diaphragm
Chamber, the Reset Plunger will need
to be depressed with added force to
push the remaining water out of the
Diaphragm Chamber and through an
openactuationdevice(e.g.,a Dry Pilot
Actuator or Solenoid Valve).
NOTE
If the Reset Knob can not be de-
pressed sufficiently to allow the Clap-
per to reseat, operate (open) the Man-
ual Control Station and then once
again push the Reset Knob with suffi-
cient force to push the water out of the
DiaphragmChamberthroughtheMan-
ual Control Station drain.
Step 6. Clean the Strainer in the Dia-
phragm Chamber Supply connection
by removing the clean-out plug and
strainer basket. The Strainer may be
flushed out by momentarily opening
the Diaphragm Chamber Supply Con-
trol Valve.
Step 7. Reset the actuation system.
Manual Actuation — Push the operat-
ing lever up; 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 pilot sprinkler, any
solder type pilot sprinklers that were
possibly exposed to a temperature
greater than their maximum rated am-
bient must be replaced.
Step 8. Openthe DiaphragmChamber
Supply Control Valve and allow time
for full pressure to build up in the Dia-
phragm Chamber.
Step 9. Operate (open) the Manual
ControlStationtovent trappedairfrom
the Diaphragm 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
throughthetopof theenclosingbox.
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 10. 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 11. Slowly open the Main Control
Valve. Close the Main Drain Valve as
soon as water discharges from the
drain connection. Observe the Auto-
maticDrain Valvefor leaks.Ifthere are
leaks, determine/correct the cause of
the leakage problem. If there are no
leaks, the DV-1 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 should be performed as indi-
cated, in addition to any specific re-
quirements of the NFPA, and any
impairment must be immediately cor-
rected.
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 the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any
authority having jurisdiction. The in-
stallingcontractororproductmanufac-
turer should be contacted relative to
any questions.
It is 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 first be given to the
owner and the fire department, central
station, 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
itcontrols,permissiontoshutdownthe
affected fire protection systems must
first be obtained from the proper
authorities and all personnel who may
be affected by this action must be no-
tified.
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
occurin thecaseofawatermainbreak
or repair), and there is a subsequent
drop in the diaphragm chamber water
pressure below its normal range (due,
for example, to a leak in a piping con-
nection 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 Model DV-1
could 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 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 toreset the
system:
Step 1. Prior to the water supply pres-
sure being restored to the closed main
control valve, note the pressure indi-
catedby thediaphragmchamber pres-
sure gauge and, whether the pressure
is within the normally expected range.
Step 2. If the diaphragm chamber
pressure 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 main control
valve, reset the Model DV-1 Deluge
Valve in accordance with the Valve
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-1 Valve
(i.e., opening of the DV-1 Valve as
during a fire condition) should be veri-
fied at least once a year as follows:
Step 1. If water must be prevented
from flowing beyond the riser, perform
the following steps.
•Close the Main Control Valve.
•Open the Main Drain Valve.
•Open the Main Control Valve one
turn beyond the position at which
water just begins to flow from the
Main Drain Valve.
•Close the Main Drain Valve.
Step 2. Determine the type of actua-
tion/detection system, and operate the
DV-1 Valve accordingly.
NOTE
Be prepared to quickly perform Steps
3, 4, and 5, if water must be prevented
from flowing beyond the riser.
•Wet Pilot Actuation — Open the
Inspector’s Test Connection.
•Dry Pilot Actuation — Open the
Inspector’s Test Connection.
•Electric Actuation — Test the del-
uge releasing panel (automatic con-
trol unit) in accordance with the
manufacturer’s instructions to ener-
gize the solenoid valve.
Step 3. Verify that the DV-1 Valve has
tripped, as indicated by the flow of
water into the system.
Step 4. Close the Diaphragm Cham-
ber Supply Control Valve.
Step 5. Close the system’s Main Con-
trol Valve.
Step 6. Reset the DV-1 Deluge Valve
in accordance with the Valve Setting
Procedure.
Five Year Internal Valve Inspection
Once every five years during the an-
nual operational test procedure and
priorto theDV-1 Valvebeingreset, the
internal parts of the DV-1 Valve should
be cleaned and then inspected for
wear and damage. Make certain that
the two 1/8 inch (3,2mm) diameter
pressure equalizing vents in the top of
the Clapper are open. Special consid-
eration should be given to the condi-
tion of the Diaphragm and the Clapper
Facing. The Diaphragm and/or Clap-
per Facing should be replaced if there
are any signs of deterioration due to
age or chemicals in the water.
NOTE
If the water supply contains chemicals
which tend to attack an EPDM type
rubber or the five year inspection indi-
cates a build-up of debris within the
valve which could affect its proper op-
eration,thenthefrequencyoftheinter-
nal valve inspection procedure should
be increased as appropriate.
Worn or damaged parts must be re-
placed and the DV-1 Valve must be
reassembled in accordance with Fig-
ure 1. The Cap Screws securing the
Diaphragm and Handhole Covers
should be uniformly tightened using a
cross-draw sequence.
