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
connections.
• Compact, Pre-Trimmed, and Semi-
Assembled, easy to operate valve
trim.
• Simple reset procedure through the
elimination of priming water.
Dry pipe sprinkler systems are used
in unheated warehouses, parking
garages, store windows, attic
spaces, loading docks, and other
areas exposed to freezing tempera-
tures, where water filled pipe cannot
be utilized. When set for service, the
dry pipe sprinkler system is pressur-
ized with air (or nitrogen). The loss of
pressure through an operated auto-
matic sprinkler 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 establishes the minimum
required system air pressure that
includes a safety factor to help prevent
false operations that might occur due
to water supply fluctuations.

Dry Pipe Valve
The TYCO 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 and
drilled per ANSI, ISO, AS, and JIS spec-
ifications (Ref. Table A). The grooved
outlet connections, as applicable, 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 protection system service. Avail-
able combinations of inlet and outlet
connections are detailed in the Order-
ing Procedure section. They are also
noted in the “Available End Connection
and Sizes” table located on Page 1.
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 Parts 2 and 3 of Figures 4,
5, and 6.
Components of the DPV-1 Valves are
shown in Figure 1. The Body and Hand-
hole Cover are ductile iron. The Hand-
hole Cover Gasket is neoprene, and
the Clapper Facing is EPDM. The Air/
Water Seat Ring is brass, the Clapper
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 Hand-
hole Cover are carbon steel.
Valve Trim
Installation dimensions are given in
Figure 7, and the Valve Trim and Pre-
Trimmed Valve Assemblies are illus-
trated in Figures 4, 5, and 6. The Valve
Trim and Pre-Trimmed Valve 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
and pre-trimmed includes the follow-
ing 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)
Also included in the Pre-Trimmed Valve
Assembly, which can be ordered sepa-
rately for the Valve Trim, includes the
following items:
• Model BFV-300 butterfly valve
• Figure 577 grooved coupling
• PS10-2 waterflow alarm switch
• PS40-2 low air pressure alarm switch
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
Table B shows the system air pres-
sure requirements as a function of the
water supply pressure. The air (or nitro-
gen) pressure in the sprinkler system
is recommended to be automatically
maintained by using one of the follow-
ing pressure maintenance devices, as
appropriate:
• Model AMD-1 Air Maintenance
Device (pressure reducing type).
• Model AMD-2 Air Maintenance
Device (compressor control type).
• Model AMD-3 Nitrogen Maintenance
Device (high pressure reducing type).
The Pressure Relief Valve provided with
the valve trim is factory set to relieve
at a pressure of approximately 45 psi
(3,1 bar). If the normal system air pres-
sure 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 accordance with the authority
having jurisdiction.
Quick Opening Device
As an option, the Model DPV-1 Dry
Pipe Valve may be equipped with the
VIZOR Electronic Dry Pipe Valve Accel-
erator (4 and 6 inch sizes) as detailed
in Technical Data Sheet TFP1105 or
the Model ACC-1 Mechanical Dry Pipe
Valve Accelerator (2-1/2, 3, 4, and 6
inch sizes) as detailed in Technical Data
She et T FP1112.
The VIZOR or the ACC-1 is used to
reduce the time to valve actuation fol-
lowing the operation of one or more
automatic sprinklers. In some cases
the use of a quick opening device
such as the VIZOR or the ACC-1 may
be required to meet the requirements of
the National Fire Protection Association
to meet water delivery times.

Operation
The TYCO Model DPV-1 Dry Pipe Valve
is a differential type valve that utilizes a
substantially lower system (air or 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 in combination 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 water supply pressure.
Table B establishes the minimum
required system air pressure that
includes a safety factor to help prevent
false operations that occur due to water
supply fluctuations.
The Intermediate Chamber of the
DPV-1 is formed by the area between
the Air Seat and Water Seat as shown in
Figure 3B. The Intermediate Chamber
normally remains at atmospheric pres-
sure through the Alarm Port connection
and the valve trim to the normally open
Automatic Drain Valve (Fig. 4, 5, or
6). Having the Intermediate Chamber,
Figure 3B, open to atmosphere is criti-
cal to the DPV-1 Valve remaining set,
otherwise the full resulting pressure of
the system air pressure on top of the
Clapper Assembly 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 Clapper Assem-
bly closed against a water supply pres-
sure of 100 psi (6,9 bar). It is for this
reason that the plunger of the Auto-
The approximate friction losses, based on the Hazen and Williams formula
and expressed in equivalent length of Schedule 40 pipe with C=100 are as
follows:
2.2 feet for the 2-1/2 inch valve at a typical flow rate of 250 GPM
4.9 feet for the 3 inch valve at a typical flow rate of 350 GPM
8.9 feet for the 4 inch valve at a typical flow rate of 600 GPM
22 feet for the 6 inch valve at a typical flow rate of 1500 GPM
matic Drain Valve must be depressed
during several of the 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 sprin-
klers. When the air pressure is suf-
ficiently reduced, the water pressure
overcomes 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 water flows 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
control valve to stop water flow, the
Clapper Assembly will latch open as
shown in Figure 3D. Latching open of
the DPV-1 will permit complete drain-
ing 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 unlatch
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
General Instructions
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 appropriate
trim diagram may prevent the DPV-1
Valve from functioning properly, as
well as void listings, approvals, and the
manufacturer’s warranties.
Failure to latch open the Clapper
Assembly prior to a system hydro-
static test may result in damage to the
Clapper Assembly.
The DPV-1 Valve must be installed in a
readily visible and accessible location.
The DPV-1 Valve and associated trim
must be maintained at a minimum tem-
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 that are
capable of preventing proper operation.
The Model DPV-1 Dry Pipe Valve is to
be installed in accordance with the fol-
lowing criteria:
• All nipples, fittings, and devices must
be clean and free of scale and burrs
before installation. Use pipe thread
sealant sparingly on male pipe
threads only.
• 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 TFP1105 for the VIZOR
Electronic Dry Pipe Valve Accel-
erator or TFP1112 for the Model
ACC-1 Mechanical Dry Pipe Valve
Accelerator.
• Care must be taken to make sure that
check valves, strainers, globe valves,
etc. are installed with the flow arrows
in the proper direction.
• Drain tubing to the drip funnel must
be installed with smooth bends that
will not restrict flow.
• The main drain and drip funnel drain
may be interconnected provided a
check valve is located at least 12
inches (300 mm) below the drip fun-
nel. The Low Body Drain Valve (Fig-
ure 4, 5, or 6) may be piped so as to
discharge into the Drip Funnel or to
a separate drain.
• Suitable provision must be made
for disposal of drain water. Drainage
water must be directed such that it
will not cause accidental damage to
property or danger to persons.
• Unused pressure alarm switch and/
or water motor alarm connections
must be plugged.
• The Pressure Relief Valve provided
with the Valve Trim is factory set to
relieve at a pressure of approximately
45 psi (3,1 bar), which can typically
be used for a maximum normal sys-
tem air pressure of 40 psi (2,8 bar).
The Pressure Relief Valve may be
reset to a lower or higher pressure;
however, it must be reset to relieve
at a pressure which is in accordance
with the requirements of the author-
ity 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 veri-
fying the desired pressure setting,
tighten the jam nut.
• Installation of an Air Maintenance
Device, as described in the Techni-
cal Data Section, is recommended.
• An Inspector’s Test Connection as
required By NFPA 13 must be pro-
vided on the system piping at the
most remote location from the Model
DPV-1 Valve.
• Conduit and electrical connections
are to be made in accordance with
the requirements of the author-
ity having jurisdiction and/or the
National Electric Code.
• Before a system hydrostatic test is
performed in accordance with NFPA
13 system acceptance test require-
ments, the Clapper Assembly is to
be manually latched open (Ref. Fig-
ure 3D); the Automatic Drain Valve
(Figure 4, 5, or 6) is to be temporar-
ily replaced with a 1/2 inch NPT plug,
the 3/32 inch Vent Fitting (Item 13,
Figure 4; Item 15, Figure 5; or Item
15, Figure 6) 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 performed
when initially setting the Model DPV-1
Dry Pipe Valve; after an operational test
of the fire protection system; or, after
system operation due to a fire.
NOTES: If the DPV-1 is equipped with
a Dry Pipe Valve Accelerator, refer to
its resetting instructions before reset-
ting the DPV-1. Refer to TFP1105 for the
VIZOR or TFP1112 for the ACC-1.
Based on the instructions provided,
reset the Accelerator at the appropriate
time during the resetting of the DPV-1.
Unless otherwise noted, refer to Figure
4, 5, or 6 to identify functional trim
components.
Step 1. Close the Main Control Valve,
and close the Air Supply Control Valve.
If the DPV-1 is equipped with a Dry
Pipe Valve Accelerator, remove the Dry
Pipe Valve Accelerator from service in
accordance with its Technical Data
Sheet (Refer to TFP1105 for the VIZOR
or TFP1112 for the ACC-1).
Step 2. 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 3. Depress the plunger of the
Automatic Drain Valve to verify that it is
open and that the DPV-1 Valve is com-
pletely drained.
Step 4. Open the Optional Alarm
Control Valve, as applicable, if it was
closed to silence local alarms.
Step 5. As necessary, replace all sprin-
klers that have operated. Replacement
sprinklers must be of the same type
and temperature rating as those which
have operated.
NOTICE
In order to prevent the possibility of
a subsequent operation of an over-
heated solder type sprinkler, any solder
type sprinklers which were possibly
exposed to a temperature greater than
their maximum rated ambient must be
replaced.
Step 6. Push down on the Reset Knob
(Figure 3E) to allow the Clapper Assem-
bly to re-seat.
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 sec-
tions. Close each drain valve as soon
as water ceases to discharge.
Also partially open the Low Body Drain
Valve to assure that the riser is com-
pletely 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
system 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
discharging.

TFP1020
Page 17 of 20
The absence of air discharging from
the Automatic Drain Valve is an indica-
tion of a properly set air seat within the
DPV-1 Valve. If air is discharging, refer
to the Care and Maintenance section
under Automatic Drain Valve Inspection
to determine/correct the cause of the
leakage problem.
Step 10. Partially open the Main
Control Valve. Slowly close the Main
Drain Valve as soon as water dis-
charges from the drain connection.
Depress the plunger on the Automatic
Drain Valve to make sure that it is open
and that there is no water discharging.
The absence of water discharging from
the Automatic Drain Valve is an indica-
tion of a properly set water seat within
the DPV-1 Valve. If water is discharg-
ing, refer to the Care and Maintenance
section under the Automatic Drain
Valve Inspection to determine/correct
the cause of the leakage problem.
If there are no leaks, the DPV-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 advise those responsible for moni-
toring 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
present.
Care and
Maintenance
The following procedures and inspec-
tions should be performed as indicated,
in addition to any specific requirements
of the NFPA, and any impairment must
be immediately corrected.
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 system must be
obtained from the proper authorities
and notify all personnel who may be
affected by action.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the
standards of any authority having juris-
diction. Contact the installing contrac-
tor or sprinkler manufacturer regarding
any questions.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
The operational test procedure and
waterflow pressure alarm test pro-
cedure 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.
Annual Operation Test Procedure
Note: Unless otherwise noted, refer to
Figure 4, 5, or 6 to identify functional
trim components.
Proper operation of the DPV-1 Valve
(i.e., opening of the DPV-1 Valve during
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
Control Valve.
Step 5. Reset the DPV-1 Valve in
accordance with the Valve Setting
Procedure.
Note: It is recommended that the
requirement of NFPA 25 to annually
inspect the inside of the valve be per-
formed at this time and prior to reset-
ting the DPV-1 Valve. Refer to the
Automatic Drain Valve Inspection sub-
section Steps 2 through 5 for instruc-
tions 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 Pressure 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
inspected monthly (per NFPA 25) to
ensure 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 check-
ing 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 subse-
quently cause a false operation should
the intermediate chamber become
inadvertently pressurized.
If leakage is present, take the DPV-1
Valve out of service (i.e., close the
main control valve, open the main drain
valve, close the air supply control valve,
remove the Dry Pipe Valve Accelerator
from service, as applicable, in accor-
dance with its Technical Data Sheet
(Refer to TFP1105 for the VIZOR or
TFP1112 for the ACC-1), and open the
Inspector’s Test Connection to relieve
the system air pressure to 0 psig as
indicated on the System Air Pressure
Gauge), and then after removing the
Handhole Cover, perform the follow-
ing 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
Facing Retainer from the Clapper
so that the Clapper Facing can be
removed and inspected. Make sure
that the Clapper Facing does not show
signs of compression set, damage, etc.
Replace the Clapper Facing if there is
any signs of wear.
Step 4. Clean the Clapper Facing,
Clapper, and Clapper Facing Retainer,
and then reassemble the Clapper
Assembly.
Step 5. Reinstall the Clapper Assembly
with its Hinge Pin and then reinstall the
Handhole Cover.
