General
Description
The Tyco®Model DPV-1 Dry Pipe
Valves are differential valves used to
automatically control the flow of water
into dry pipe fire protection sprinkler
systems upon operation of one or
more automatic sprinklers. The DPV-1
also provides for actuation of fire
alarms upon system operation. The
Model DPV-1 features are as follows:
•External reset.
•250 psi (17,2 bar) pressure rating.
•Unique offset single clapper design
enabling a simple compact valve to
minimize installation labor.
•Ductile iron construction to ensure a
lightweight valve to minimize ship-
ping cost.
•A variety of inlet and outlet connec-
tions.
•Compact, semi-preassembled or
fullyassembled,andeasytooperate
valve trim.
•Simple reset procedure through the
elimination of priming water.
Dry pipe sprinkler systems are used in
unheated warehouses, parking ga-
rages, store windows, attic spaces,
loading docks, and other areas ex-
posedtofreezingtemperatures,where
water filled pipe cannot be utilized.
When set for service, the dry pipe
sprinklersystemis pressurizedwithair
(or nitrogen). The loss of pressure
through an operated automatic sprin-
kler in response to heat from a fire
permits the DPV-1 Dry Pipe Valve to
open and allow a flow of water into the
sprinkler system piping. Table B es-
tablishes the minimum required sys-
tem air pressure that includes a safety
factor to help prevent false operations
that might occur due to water supply
fluctuations.
WARNING
The Model DPV-1 Dry Pipe 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 performance of these de-
vices.
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 with any
questions.

Technical
Data
Approvals:
UL and C-UL Listed. FM Approved.
NYC under MEA 172-02-E (4 and 6
inch).
DryPipeValve:
The Model DPV-1 Dry Pipe Valves are
for vertical installations (flow going
up), and they are rated for use at a
maximum service pressure of 250 psi
(17,2 bar). The Valve dimensions are
shown in Figure 7.
Flanged connections are available
drilled per ANSI, ISO, AS, and JIS
specifications (Ref. Table A). The
grooved outlet connections, as appli-
cable, are cut in accordance with
standard groove specifications for
steel pipe. They are suitable for use
with grooved end pipe couplings that
are listed or approved for fire protec-
tion system service. Available combi-
nations of inlet and outlet connections
are detailed in the Ordering Procedure
section.
Threaded port connections of valves
having flanges drilled to ANSI, AS, or
JIS specifications are NPT threaded
per ANSI Standard B1.20.1. Threaded
port connections of valves having
flanges drilled to ISO are available
either threaded per ISO 7/1 or NPT
threaded per ANSI Standard B1.20.1.
Valves with NPT threaded ports will
readily accept the trim arrangements
detailed in Figures 4, 5, and 6.
Components of the DPV-1 Valves are
shown in Figure 1. The Body and
Handhole Cover are ductile iron. The
Handhole Cover Gasket is neoprene,
and the Clapper Facing is EPDM. The
Air/Water Seat Ring is brass, the Clap-
per is bronze or aluminum bronze, and
both the Clapper Retaining Plate and
Latch are bronze. The Hinge Pin is
aluminum bronze, and the fasteners
for the Handhole Cover are carbon
steel.
Valve Trim:
Installation dimensions are given in
Figure 7, and the Valve Trim is illus-
trated in Figures 4, 5, and6. TheValve
Trim forms a part of the laboratory
listings and approval of the DPV-1
Valve and is necessary for the proper
operation of the DPV-1 Valve. Each
package of trim includes the following
items:
•Water Supply Pressure Gauge
•System Air Pressure Gauge
•Air Supply Connections
•Main Drain Valve
•Low Body Drain Valve
•Alarm Test Valve
•Automatic Drain Valve
•Drip Funnel
•Connections For Optional Quick
Opening Device (Accelerator)
NOTE
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
gauge with a separately ordered 600
psi (41,4 bar) Water Pressure Gauge.
Air Supply:
TableBshows thesystem airpressure
requirementsas afunctionofthewater
supply pressure. The air (or nitrogen)
pressure in the sprinkler system is rec-
ommended to be automatically main-
tained by using one of the following
pressure maintenance devices, as ap-
propriate:
•Model AMD-1 Air Maintenance De-
vice (pressure reducing type).
•Model AMD-2 Air Maintenance De-
vice (compressor control type).
•Model AMD-3 Nitrogen Mainte-
nance Device (high pressure reduc-
ing type).
The Pressure Relief Valve provided
with the valve trim is factory set to
relieve at a pressure of approxi-
mately 45 psi (3,1 bar). If the normal
system air pressure is less than or
exceeds 40 psi (2,8 bar), then the
pressure Relief Valve must be reset to
relieve at a pressure that is in accord-
ance with the Authority Having Juris-
diction.
Quick Opening Device:
As an option, the Model DPV-1 Dry
Pipe Valve may be equipped with the
Model QRS Electronic Dry Pipe Valve
Accelerator (4 and 6 inch sizes) as
detailed in Technical Data Sheet
TFP1100 or the Model ACC-1 Me-
chanical Dry Pipe Valve Accelerator
(2-1/2, 3, 4, and 6 inch sizes) as de-
tailed in Technical Data Sheet
TFP1112.
TheQRSortheACC-1isusedtore-
duce the time to valve actuation fol-
lowing the operation of one or more
automatic sprinklers. In some cases

Operating
Principles
The Model DPV-1 Dry Pipe Valve is a
differential type valve that utilizes a
substantially lower system (airor nitro-
gen) pressure than the supply (water)
pressure, to maintain the set position
shown in Figure 3A. The differential
nature of the DPV-1 is based on the
area difference between the air seat
and the water seat incombination with
the ratio of the radial difference from
the Hinge Pin to the center of the
Water Seat and the Hinge Pin to the
center of the Air Seat. The difference
is such that 1 psi (0,07 bar) of system
air pressure can hold approximately
5.5 psi (0,38 bar) of watersupply pres-
sure.
Table B establishes the minimum re-
quired system air pressure that in-
cludes a safety factor to help prevent
false operations that occur due to
water supply fluctuations.
The Intermediate Chamber of the
DPV-1isformedbytheareabetween
the Air Seat and Water Seat as shown
in Figure 3B. The Intermediate Cham-
ber normally remains at atmospheric
pressure through the Alarm Port con-
nection and the valve trim to the nor-
mally open Automatic Drain Valve
(Fig. 4, 5, or 6). Having the Intermedi-
ate Chamber, Figure 3B, open to at-
mosphere is critical to the DPV-1
Valve remaining set, otherwise the full
resulting pressure of the system air
pressure on top of the Clapper Assem-
bly cannot be realized.
For example and assuming a water
supply pressure of 100 psi (6,9 bar), if
the system air pressure is 25 psi (1,7
bar) and there was 15 psi (1,0 bar)
pressure trapped in the Intermediate
Chamber, the resulting pressure
across the top of the Clapper would
only be 10 psi (0,7 bar). This pressure
would be insufficient to hold the Clap-
per Assembly closed against a water
supply pressure of 100 psi (6,9 bar). It
isfor thisreason thattheplunger ofthe
Automatic Drain Valve must be de-
pressed during several ofthe resetting
steps, as well as during inspections,
making certain that the Automatic
Drain Valve is open.
When one or more automatic sprin-
klers operate in response to a fire, air
pressure within the system piping is
relieved through the open sprinklers.
When the air pressure is sufficiently
reduced, the water pressure over-
comes the differential holding the
Clapper Assembly closed and the
Clapper Assembly swings clear of the
water seat, as shown in Figure 3C,
This action permits water flow into the
system piping and subsequently to be
discharged from any open sprinklers.
Also, with the Clapper Assembly open,
the intermediate chamber is pressur-
ized and waterflows through the alarm
port (Ref. Figure 3B) at the rear of the
DPV-1 Valve to actuate system water
flow alarms. The flow from the alarm
port is also sufficient to close the oth-
erwise normally open Automatic Drain
Valve in the valve trim.
After a valve actuation and upon sub-
sequent closing of a system main con-
trol valve to stop water flow, the Clap-
per Assembly will latch open as shown
in Figure 3D. Latching open of the
DPV-1 will permit complete draining of
the system (including any loose scale)
through the main drain port.
During the valve resetting procedure
and after the system is completely
drained, the external reset knob can
be easily depressed to externally un-
latch the Clapper Assembly as shown
in Figure 3E. As such, the Clapper
Assembly is returned to its normal set
position to facilitate setting of the dry
pipe sprinkler system, without having
to remove the Handhole Cover.

Installation
NOTES
Proper operation of the Model DPV-1
Dry Pipe 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 DPV-1 Valve from functioning
properly, as well as void listings, ap-
provals, and the manufacturer’s war-
ranties.
Failure to latch open the Clapper As-
sembly prior to a system hydrostatic
test may result in damage to the Clap-
per Assembly.
The DPV-1 Valve must be installed in
a readily visible and accessible loca-
tion.
The DPV-1 Valve and associated trim
mustbe maintainedat aminimumtem-
perature of 40°F/4°C.
Heat tracing of the DPV-1 Valve or its
associated trim is not permitted. Heat
tracing can result in the formation of
hardened mineral deposits thatare ca-
pable of preventing proper operation.
The Model DPV-1 Dry Pipe Valve is to
be installed in accordance with the fol-
lowing 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.
Step 2. The DPV-1 Valve must be
trimmed in accordance with Figures 4,
5, or 6, as applicable. If the DPV-1 is
to be equipped with a Dry Pipe Valve
Accelerator, refer to the Technical
Data Sheet TFP1100 for the Model
QRS Electronic Dry Pipe Valve Accel-
erator or TFP1112 for the Model ACC-
1 Mechanical Dry Pipe Valve Accel-
erator.
Step 3. Care must be taken to make
sure that check valves, strainers,
globe valves, etc.are installedwith 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
inches(300mm) belowthedrip funnel.
The Low Body Drain Valve (Fig. 4, 5,
or 6) may be piped so as to discharge
into the Drip Funnel or to a separate
drain.
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. Unused pressure alarm switch
and/or water motor alarm connections
must be plugged.
Step 8. ThePressure ReliefValvepro-
vided with the Valve 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 normal
system air pressure of 40 psi (2,8 bar).
The Pressure Relief Valve may be re-
set to a lower or higher pressure; 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 9. Installation of an Air Mainte-
nance Device, as described in the
Technical Data Section, is recom-
mended.
Step 10. An Inspector’s Test Connec-
tion as required By NFPA 13 must be
provided on the system piping at the
most remote location from the Model
DPV-1 Valve.
Step 11. Conduit and electrical con-
nectionsareto bemade inaccordance
with the requirements of the authority
having jurisdiction and/or the National
Electric Code.
Step 12. 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.
3D); the Automatic Drain Valve (Fig. 4,
5, or 6) is to be temporarily replaced
with a 1/2 inch NPTplug, the 3/32 inch
Vent Fitting (Item 13, Fig. 4; Item 15,
Fig. 5; or Item 15, Fig. 6) is to be
temporarily replaced with a 1/4 inch
NPT plug, and the Handhole Cover
Boltsareto betightenedusingacross-
draw sequence.
Valve Setting
Procedure
Steps 1 through 11 are to be per-
formed when initially setting the Model
DPV-1 Dry Pipe Valve; after an opera-
tional test of the fire protection system;
or, after system operation due to afire.
NOTES
If the DPV-1 is equipped with a Dry
Pipe Valve Accelerator, refer to its re-
setting instructions before resetting
the DPV-1. Refer to TFP1100 for the
QRS or TFP1112 for the ACC-1.
Basedon theinstructionsprovided,re-
set the Accelerator at the appropriate
time during the resetting of the DPV-1.
Step 1. Close the Main Control Valve,
and close the Air Supply Control Valve
(Fig.4,5,or6).IftheDPV-1is
equipped with a Dry Pipe Valve Accel-
erator, remove the Dry Pipe Valve Ac-
celerator from service in accordance
with its Technical Data Sheet (Referto
TFP1100 for the QRS or TFP1112 for
the ACC-1).
Step 2. Open the Main Drain Valve
(Fig. 4, 5, or 6) and all auxiliary drains
in the system. Close the auxiliary drain
valves after water ceases to dis-
charge. Leave the Main Drain Valve
open.
Step 3. Depress the plunger of the
Automatic Drain Valve (Fig. 4, 5, or 6)
to verify that it is open and that the
DPV-1 Valve is completely drained.
Step 4. Open the Optional Alarm Con-
trol Valve (Fig. 4, 5, or 6), as applica-
ble, if it was closed to silence local
alarms.
Step 5. As necessary, replace all
sprinklers that have operated. Re-
placement sprinklers must be of the
same type and temperature rating as
those which have operated.
NOTE
In order to prevent the possibility of a
subsequent operation of an over-
heated solder type sprinkler, any sol-
der type sprinklers which were possi-
bly exposed to a temperature greater
than their maximum rated ambient
must be replaced.
Step 6. Push down on the Reset Knob
(Fig. 3E) to allow the Clapper Assem-
bly to reseat.
Step 7. Pressurize the system with air
(or nitrogen) to 10 psi (0,7 bar), and
then individually open all auxiliary
drain valves in the system piping to
drain any remaining water in trapped
sections. Close each drain valve as
soon as water ceases to discharge.
Page 16 of 20 TFP1020

Also partially open the LowBody Drain
Valve (Fig. 4, 5, or 6)to assure that the
riser is completely drained. Close the
Low Body Drain Valve as soon as
water ceases to discharge.
Step 8. Refer to Table B and then
restore the system to the normal sys-
tem air pressure as necessary to hold
the DPV-1 Valve closed.
Step 9. Depress the plunger on the
Automatic Drain Valve to make sure it
is open and that there is no air dis-
charging.
The absence of air discharging from
the Automatic Drain Valve is anindica-
tion of a properly set air seat within the
DPV-1Valve.Ifairisdischarging,refer
to the Care and Maintenance section
under Automatic Drain Valve Inspec-
tion to determine/correct the cause of
the leakage problem.
Step 10. Partially open the Main Con-
trol Valve. Slowly close the Main Drain
Valve as soon as water discharges
from the drain connection.
Depress the plunger on the Automatic
DrainValvetomakesurethatitisopen
and thatthere is no water discharging.
The absence of water discharging
from the Automatic Drain Valve is an
indication of a properly set water seat
within the DPV-1 Valve. If water is dis-
charging, refer to the Care and Main-
tenance section under the Automatic
Drain Valve Inspection to deter-
mine/correct the cause of the leakage
problem.
If there are no leaks, the DPV-1 Valve
is ready tobe placed in serviceand 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.
Step 11. Once a week after a valve is
reset following an operational test or
system operation, the Low Body Drain
Valve (and any low point drain valves)
should be partially opened (and then
subsequently closed) to relieve drain-
back water. Continue this procedure
until drain-back water is no longer pre-
sent.
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-
stallingcontractor orproductmanufac-
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
The operational test procedure and
waterflow pressure alarm test proce-
dure will result in operation of the as-
sociated alarms. Consequently, notifi-
cation must first be given to the owner
and the fire department, central sta-
tion,or othersignalstationtowhichthe
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 decision must be
notified.
Annual Operation Test Procedure
Proper operation of the DPV-1 Valve
(i.e., opening of the DPV-1 Valve dur-
ing a fire condition) should be verified
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. Open the system’s Inspector’s
Test Connection.
Step 3. Verify that the DPV-1 Valve
has operated, as indicated by the flow
of water into the system and that all
waterflow alarms operate properly.
Step 4. Close the system’s Main Con-
trol Valve.
Step 5. Reset the DPV-1 Valve in ac-
cordancewiththeValveSettingProce-
dure.
NOTE
It is recommended that the require-
ment of NFPA 25 to annually inspect
the inside of the valve be performed at
this time and prior to resetting the
DPV-1 Valve. Refer to the Automatic
Drain Valve Inspection sub-section
Steps 2 through 5 for instructions with
regard to the inspection of the Clapper
Facing.
Quarterly Waterflow Alarm Test
Procedure
Testing of the system waterflow
alarms should be performed quarterly.
To test the waterflow alarm, open the
Alarm Test Valve, which will allow a
flow of water to the Waterflow Pres-
sure Alarm Switch and/or Water Motor
Alarm. Upon satisfactory completion
of the test, close the Alarm Test Valve.
Water Pressure Inspection
The Water Pressure Gauge is to be
inspected monthly (per NFPA 25) to
ensure that normal system water pres-
sure is being maintained.
Air Pressure Inspection
The Air Pressure Gauge is to be in-
spected monthly (per NFPA 25) to en-
sure that normal system air pressure
is being maintained.
Automatic Drain Valve Inspection
The Automatic Drain Valve should be
inspected monthly (per NFPA 25) by
depressing the plunger and checking
to ensure that the Automatic Drain
Valve is not discharging water and/or
air. A discharge of water and/or air is
an indication that the air and/or water
seats are leaking, which could sub-
sequently cause a false operation
should the intermediate chamber be-
come inadvertently pressurized.
If leakage is present, take the DPV-1
Valve out of service (i.e., close the
main control valve, open the main
drainvalve,closetheairsupplycontrol
valve, remove the Dry Pipe Valve Ac-
celerator from service, as applicable,
in accordance with its Technical Data
Sheet (Refer to TFP1100 for the QRS
or TFP1112 for the ACC-1), and open
the Inspector’s Test Connection to re-
lieve the system air pressure to 0 psig
as indicated on the System Air Pres-
sure Gauge), and then after removing
Page 17 of 20
TFP1020

the Handhole Cover, perform the fol-
lowing steps:
Step 1. Make sure that the Seat Ring
is clean and free of any nicks or signifi-
cant scratches.
Step 2. Remove the Clapper Assem-
bly from the valve by first pulling out
the Hinge Pin.
Step 3. Disassemble the Clapper Fac-
ing Retainer from the Clapper so that
the Clapper Facing can be removed
and inspected. Make sure that the
Clapper Facing does not showsigns of
compression set, damage, etc. Re-
placetheClapperFacingifthereis any
signs of wear.
Step 4. Clean the Clapper Facing,
Clapper,andClapperFacingRetainer,
and then reassemble the Clapper As-
sembly.
Step 5. Reinstall the Clapper Assem-
bly with its Hinge Pin and then reinstall
the Handhole Cover.
