DRY PIPE VALVE - 4 and 6 INCH (100 and 150 mm)
MODEL F302 (FLANGE x FLANGE) & F3021 (FLANGE x GROOVE)
The 4 and 6 inch (100 and 150 mm),
Model F302 and F3021 Dry Pipe
Valves are differential, latch type
valves used to automatically control
the flow of water into dry pipe fire pro-
tection sprinkler systems upon opera-
tion of one or more automatic sprin-
klers. The F302 and F3021 also
provide for actuation of fire alarms
upon system operation.
Both model valves have flanged inlet
connections and are identical with the
exception of the outlet connection. The
Model F302 has a flanged outlet con-
nection, whereas the Model F3021 has
a grooved outlet connection.
Dry pipe sprinkler systems are typi-
cally used in unheated warehouses,
parking garages, store windows, attic
spaces, loading docks, and similar ar-
eas exposed to freezing temperatures,
where water filled pipe cannot be util-
ized. When set for service, a dry pipe
sprinkler system is pressurized with air
(or nitrogen), and the loss of air pres-
sure through an operated automatic
sprinkler, in response to heat from a
fire, permits the dry pipe valve to open
and allow a flow of water into the sprin-
kler system piping. The differential de-
sign of the F302/F3021 is such that the
minimum air pressure in the piping is
approximately one-sixth of the static
water supply pressure, with an added
20 psi (1,4 bar) safety factor, to help
prevent a false operation that might
otherwise occur due to water supply
pressure fluctuations.

Dry Pipe Valve:
The 4 and 6 inch (100 and 150 mm)
Model F302/F3021 Dry Pipe Valves
are rated for use at a maximum service
pressure of 175 psi (12,l bar). The
Valve dimensions are shown in Figure
A, and all of the ports are NPT
threaded per ANSI Standard B1.20.1.
“Standard order” flanged connections
are drilled per ANSI specifications
shown in Table A, and on a “special
order” basis flanged connections are
available drilled per IS0 specifications.
The grooved outlet connection of the
Model F3021 is cut in accordance with
Gruvlok standard groove specifica-
tions for steel pipe, and it is suitable for
use with grooved end pipe couplings
that are listed or approved for fire pro-
tection system service.
The F302 and F3021 Valves are to be
installed vertically, as shown in Figure
A. Exterior surfaces of the Body and
Covers are painted red. The year of
manufacture and serial number are
metal stamped on the edge of the inlet
flange, and the year of manufacture
also appears on the Handhole Cover.
The nominal pressure losses versus
flow are shown in Graphs A-l and A-2.
The approximate friction losses, based
on the Hazen and Williams formula
and expressed in equivalent length of
Schedule 40 pipe with C = 100, is 6.4
feet of 4 inch pipe for the 4 inch (100
mm) valve size and 9.6 feet of 6 inch
pipe for the 6 inch (150 mm) valve size.
The equivalent length of pipe has been
calculated on the basis of the flow
rates typically used with each size
valve.

Table B shows the svstem air Pressure
requirements as a function of ihe water
supply pressure. The air pressure in
the sprinkler system is recommended
to be automatically maintained by us-
ing one of the following pressure main-
tenance devices, as appropriate, and
nitrogen pressure may be used in lieu
of air pressure.
l Model F324 Air Maintenance De-
vice (pressure reducing type), re-
fer to Technical Data Sheet
TDlll.
l Model F326 Air Maintenance De-
vice (compressor control type), re-
fer to Technical Data Sheet
TD112.
. Model F328 Nitrogen Mainte-
nance Device (high pressure re-
ducing type), refer to Technical
Data Sheet TDI 13.
The Pressure Relief Valve (Item 9 - Fig.
F) is factory set to relieve at a pres-
sure of approximately 45 psi (3,l
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 which is
in accordance with the requirements of
the Authority Having Jurisdiction.
Quick Opening Device:
As an option, the Model F302/F3021
Dry Pipe Valves may be equipped with
the Model F311 Dry Pipe Valve Accel-
erator described in Technical Data
Sheet TD109.
The F311 is used for the purpose of
obtaining a reduction in the time to
valve operation following the operation
of one or more automatic sprinklers,
and in some cases may be required to
meet the requirements of the National
Fire Protection Association for sys-
tems having a capacity greater than
500 gallons (1890 litres).
The Model F302/F3021 Dry Pipe
Valves are differential, latch type
valves that utilize a substantially lower
system (air) pressure than the supply
(water) pressure, to maintain the set
position shown in Figure C-l. The dif-
ferential nature of the F302/F3021 is
provided by a linkage mechanism
which provides the majority of force
necessary to hold the waterway Clap-
per closed. The difference is such that
1 psi (0,07 bar) of system air pressure
can hold approximately 6 psi (0.4 bar)
of water supply pressure.
The minimum system air pressure
(Ref. Table B) is, therefore, calculated

to be approximately l/6 of the static
water supply pressure, plus a 20 psi
(1,4 bar) safety factor, to help prevent
a false operation that might otherwise
occur due to water supply pressure
fluctuations.
Priming water within the body of the
F302/F3021 Valves, as shown in Fig-
ure C-l, helps to maintain a tight air
seal at the two air seats. System air
pressure entering the Auxiliary Cham-
ber Cover via the Communicating Port
presses inward against the Auxiliary
Clapper Assembly. The Auxiliary Clap-
per Assembly in turn bears against the
Clapper Latch, which is engaged with
the Waterway Clapper Assembly to
hold the F302lF3021 Valve closed.
An intermediate chamber is formed
adjacent to the air seats (2 places) and
by the interconnecting valve trim (Ref.
Figure D). The intermediate chamber
is normally open to atmosphere
through the Automatic Drain Valve
(Ref. Figure D).
Having the intermediate chamber
open to atmosphere is critical to the
F302/F3021 Valve remaining set, oth-
erwise the full resulting pressure of the
system air pressure exerted on the
Auxiliary Clapper Assembly cannot be
realized. For example, if the system
air pressure is 40 psi (2,7 bar) and
there was 25 psi (1,7 bar) pressure
trapped in the intermediate chamber,
the resulting pressure across the Aux-
iliary Clapper Assembly would only be
15 psi (1,Obar), which would be insuf-
ficient to hold the Waterway Clapper
Assembly closed against a water
supply pressure of 100 psi (6,9 bar). It
is for this reason that the plunger of the
Automatic Drain Valve should be de-
pressed several times during resetting
of the F302/F3021 Valve, as well as
during inspections, to make certain
that the Automatic Drain Valve is open.

NOMINAL PRESSURE LOSS VERSUS FLOW
When one or more automatic sprin-
klers operate in response to a fire, air
pressure within the system piping is
relieved. When the air pressure be-
comes sufficiently reduced and with
the resulting decrease of force exerted
on the Auxiliary Clapper Assembly, the
water pressure overcomes the differ-
ential holding the Waterway Clapper
Assembly closed and the Waterway
Clapper Assembly swings clear of the
water seat to permit waterflow into the
system piping and subsequently to be
discharged from any open sprinklers.
Under full flow conditions, the Water-
way Clapper Assembly will latch open
as shown in Figure C-2. Also, with the
Waterway Clapper Assembly open,
the intermediate chamber is pressur-
ized and water flows, via the groove in
the Seat Ring, through the alarm port
at the rear of the F302IF3021 Valve to
actuate the system waterflow alarms.
The flow from the alarm port is also
sufficient to close the otherwise nor-
mally open Automatic Drain Valve (Ref.
Figure D and Item 11, Fig. F).

NOTES
Proper operation of the Model
F302lF3021 Dry Pipe Value depends
upon its trim being installed in ac-
cordance with the instructions given
in this TechnicalData Sheet. Failure
to follow the trim diagram or the in-
structions given in this Technical
Data Sheet may prevent the
F302lF3021 Valve from functioning
properly, as well as void listings, ap-
provals, and the manufacturer’s war-
ranties.
The F302lF3021 Valves are shipped
with a restraining wire tied around
the Clapper Latch and Clapper Arm
to prevent movement of these compo-
nents during shipment.The restrain-
ing wire must be removed. Failure to
do so will prevent the F302lF3021
Valvefrom functioning properly.
The F302lF3021 Valve must be in-
stalled in a readily visible and acces-
sible location.
The F302lF3021 Valve and associ-
ated trim must be maintained at a
minimum temperature of 40°F/4”C.
Heat tracingofthe F302lF3021 Valve
or its associated trim is notpermitted.
Heat tracing can result in the forma-
tion of hardened mineral deposits
which are capable of preventing
proper operation.
The Model F302IF3021 Dry Pipe Valve
is to be installed in accordance with
the following criteria:
1. 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
2. The F302/F3021 Valve must be
trimmed in accordance with Figure
E
3. Care must be taken to make sure
that check valves, strainers, globe
valves, etc. are installed with the flow
arrows in the proper direction.
4. Drain tubing to the drip funnel must
be installed with smooth bends that
will not restrict flow.
5. 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.
6. 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.
7. Unused pressure alarm switch
and/or water motor alarm connec-
tions must be plugged.
8. The Pressure Relief Valve provided
with the Valve Trim is factory set to
relieve at a pressure of approxi-
mately 45 psi (3,l bar), which can
typically be used for a maximum nor-
mal system 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 be re-
set to relieve at a pressure which 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 - clock-
wise for a higher pressure setting or
counterclockwise for a lower pres-
sure setting. After verifying the de-
sired pressure setting, tighten the
jam nut.
9. Installation of an Air Maintenance
Device, as described in the Techni-
cal Data Section, is recommended.
10. 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
F302lF3021 Valve.
11. Conduit and electrical connections
are to be made in accordance with
the requirements of the authority
havina iurisdiction and/or the Na-
tional”El&tric Code.
12. Before hydrostatic tests are per-
formed in accordance with NFPA 13
system acceptance test require-
ments, the Waterway Clapper As-
sembly is to be manually latched
open (Ref. Figure C-2); the Automat-
ic Drain Valve (Item 1l-Fig. F) is to
be temporarily replaced with a l/2
inch NPT pipe plug; and, the Auxil-
iary Clapper Cover Screws, as well
as Handhole Cover Bolts, are to be
tightened using a cross-draw se-
quence.
Steps 1 through 17 are to be per-
formed when initially setting the Model
F302lF3021 Dry Pipe Valve; after an
operational test of the fire protection
system; or, after system operation due
to a fire.
1. Close the Main Control Valve, close
the Air Supply Control Valve, and
close the Accelerator Control Valve,
if applicable.
2. Open the Main Drain Valve and all
auxiliary drains in the system. Close
the auxiliary drain valves after water
3.
ceases to discharge. Leave the Main
Drain Valve open.
Depress the plunger of the Automat-
ic Drain Valve to verify that it is open
and that the F302/F3021 Valve is
completely drained.
4. Verify that both the Air and Water
Pressure Gauges are reading zero
(0).
5. Open the Alarm Control Valve (Fig.
F), if it was closed to silence local
alarms.
It is recommended that the Alarm
Control 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.
6. Disassemble the Y-Strainer (Item 10,
Fig. F), thoroughly clean-out the
basket, and then reassemble the Y-
Strainer.
7. As necessary, replace all sprinklers
that have operated. Replacement
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
overheated solder type sprinklel;
any solder type sprinklers which
were possibly exposed to a tem-
perature greater than their maxi-
mum rated ambient must be re-
placed.
8. Remove the Handhole Cover, and
then remove the Auxiliary Clapper
Cover, being careful not to lose the
Auxiliary Clapper Spring.
Thoroughly clean all interior parts of
the F302/F3021 Valve, and make
certain that the Communicating Port
(Ref. Fig. C-l ) between the Body and
the Auxiliary Clapper Cover is wide
open.
Use a clean cloth to to wipe the
Auxiliary and Waterway Clapper
Seat Rings, as well as the Clapper
Facings. Inspect the Clapper Fac-
ings and Seat Rings for damage.
After unlatching the Waterway Clap-
per Assembly from its tripped
(latched) position (Ref. Figure C-2),
check the Waterway Clapper As-
sembly, Auxiliary Clapper Assembly,
Clapper Latch, Upper Latch and
Lower Latch for freedom of move-
ment.
When checking the Auxiliary Clap-
per Assembly for freedom of move-
-7-
OBSOLETE

ment, make certain that it moves
freely all the way into and out of the
Auxiliary Seat Ring, and that the
Auxiliary Clapper Rod is completely
lubricated its entire length with Dow
Corning Fiurosilicone FS3452
grease. If any binding is experi-
enced, check the entire length of the
Clapper Rod for damage.
Worn or damaged parts must be
replaced and the F302/F3021 Valve
must be reassembled in accordance
with Figure B.
9. Reseat the Waterway Clapper As-
sembly, engage the Clapper Latch
with the nose of the waterway Clap-
per Arm, and check for proper seat-
ing of the Auxiliary Clapper Assem-
bly according to Figure G.
NOTE
Make certain that theLower Latch
does not prevent the Waterway
Clapper Assembly from being
properly seated. When the Water-
way Clapper Assembly isproperly
seated, the Lower Latch should be
able to swivel freely.
10. Replace the Auxiliary Clapper Cover
and Gasket making certain that the
Auxiliary Clapper Spring is in place.
Tighten the Auxiliary Clapper Cover
Screws using a cross-draw se-
quence.
Reach inside the Handhole Cover
opening and try to spin the Auxiliary
Clapper Rod of the Auxiliary Clapper
Assembly between your thumb and
index finger. If it spins with some
resistance or does not spin at all,
then the Auxiliary Clapper Facing is
adequately seated against the Aux-
iliary Seat Ring (i.e., the Auxiliary
Clapper Facing is binding against
the Auxiliary Seat Ring). If it freely
spins, then pull it towards the Clap-
per Latch until it no longer spins or
resistance to spinning is encoun-
tered. Ifadequate seating of the Aux-
iliary Clapper Facing cannot be ob-
tained, as is evidenced by a Auxiliary
Rod that spins freely, remove the
Auxiliary Clapper Cover and refer to
Figure G.
Replace Handhole Cover and Gas-
ket. Tighten the Handhole Cover
Screws using a cross-draw se-
quence.
11. Open the Priming Valve, and open
the Priming Test Valve.
Prime the F302/F3021 Valve by
slowly pouring water into the Priming
Cup. When water discharges from
the Priming Test Valve, cease pour-
ing water into the Priming Cup. The
4 Inch (100 mm) F302/F3021 Valve
will require approximately 1.4 gal-
lons (5.3 litres) of prime water, and
the 6 Inch (150 mm) F302/F3021
Valve will require approximately 3.0
gallons (11,4 litres) of prime water.
After water stops discharging from
the Priming Test Valve, close the
Priming Valve and the Priming Test
Valve.
NOTE
Slight weepage of prime water
from the Automatic Drain Valve
may be ignored until Step 12 is
completed.
12. Pressurize the system with air (nitro-
gen) to 20 psi (1,4 bar). Depress the

Valve as during a fire condition) should
be verified at least once a year as
follows:
1.
2.
3.
4.
5.
Ifwater must be prevented from flow-
ing beyond the riser, perform the fol-
lowing steps.

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.
Open the system’s Inspector’s Test
Connection.
Verify that the F302/F3021 Valve has
operated, as indicated by the flow of
water into the system and that all
waterflow alarms operated properly.
Close the system’s Main Control
Valve.
Reset the F302/F3021 Valve in ac-
cordance with the Valve Setting Pro-
cedure.
Quarterly Waterflow Alarm Test properly seated Auxiliary Clapper
Procedure Assembly.
B. Waterway Clapper Assembly:
Make sure that the Clapper Facing
does not show signs of compression
set, damage, etc. Replace the Clap-
per Facing if there are any signs of
wear.
Refer to Figure B and make certain
that the Waterway Clapper Assem-
bly is properly assembled. Special
attention should be given to the ar-
rangement order of the Clapper,
Clapper Facing, Clapper Washer,
and Belleville Spring. The tapered
side of the Clapper Washer must
face up and the recessed side of the
Belleville Spring must face up.
The Automatic Drain Valve should be
inspected at least each week by de-
pressing the plunger and checking to
ensure that the Automatic Drain Valve
is not discharging water and/or air. Dis-
charging of water and/or air is an indi-
cation that the air and/or water seats
are leaking, which could subsequently
cause a false operation should the in-
termediate chamber become inadver-
tently pressurized.
If leakage is present, take the
F302/F3021 Valve out of service (i.e.,
close the main control valve, open the
main drain valve, close the accelerator
control valve (if applicable), close the
air supply control valve, and open the
Inspector’s Test Connection to relieve
the system air pressure to zero (0) as
indicated on the System Air Pressure
Gauge). Remove the Handhole Cover
and Auxiliary Clapper Cover and then
check the following items:
A. Auxiliary Clapper Assembly. Make
sure that the Auxiliary Clapper Fac-
ing does not show signs of compres-
sion set, damage, etc. Replace the
Clapper Facing if there are any signs
of wear.
Refer to Figure B and make certain
that the Auxiliary Clapper Assembly
is properly assembled. Special at-
tention should be given to the ar-
rangement order of the Auxiliary
Clapper, Auxiliary Clapper Facing,
and Auxiliary Clapper Facing Re-
tainer.
C.
The Lower Clapper Nut should be
snugly tightened. Check for over-
tightening. Over tightening can
cause the Clapper Facing to become
slightly warped and thereby prevent
proper seating.
Seat Rings: Inspect the Seat Rings
for nicks, damage, etc. If the Seat
Rings are damaged, the
F302/F3021 Valve will require re-
placement, since the Seat Rings are
not field replaceable.
Priming Water Inspection
After a full flow annual operation test
procedure or after a system operation,
the priming level of the F302/F3021
Valves is to be inspected at least once
each week, for one month. Otherwise,
the priming level is to be inspected at
least quarterly. Partially open the Prim-
ing Test Valve, and then close the Prim-
ing Test Valve when the priming level
has been correctly established (i.e.,
when water stops discharging from the
Priming Test Valve).
If no water discharges, close the Prim-
ing Test Valve and replenish the Prim-
ing Level by performing Steps 1, 2, 3,
4, 11, 12. 14, 15, 16, and 17 in the
Valve Setting Procedure section.

With the Clapper Latch (14) engaged with the Clapper Arm (34) and with about a 5 to 10 lb. force applied by hand against
the Auxiliary Clapper Assembly, the appearance of the seated Auxiliary Clapper Facing (22) should be as shown in the above
illustration (i.e., the seated Auxiliary Clapper Facing should be essentially straight up & down to slightly inward.
If the seated Auxiliary Clapper Facing (22) does not appear as shown, adjust the Push Rod Screw (16) in or out, accordingly,
by first loosening the Push Rod Screw Locknut (36). After adjusting the Push Rod Screw (16) to obtain proper seating of the
Auxiliary Clapper Facing (22), tighten the Push Rod Screw Locknut (36).
NOTES
Valves manufactured before 1983 utilized a Spiro1 Pin in addition to the Push Rod Screw Locknut (361, to hold the
Push Rod Screw (16) setting. On a temporary basis, the Spiro1 Pin may be removed to facilitate readjustment of the
Push Rod Screw (16); howevel; it is recommended that the Push Rod (171, Push Rod Screw (161, and Push Rod Screw
Locknut (36) be replaced as soon aspossible in accordance with Item B of the Field Service Notes & Recommendations
given on Page 13.
When loosening or tightening the Push Rod Screw Locknut (36), only apply wrenches to the wrench ji!atsof the Push
Rod (17) and Push Rod Screw Locknut (361, to avoid scoring of the Push Rod (17). Scoring of the Push Rod could
result in a failure of the Dry Pipe Valve to properly operate. A scored Push Rod must be replaced before placing the
Dry Pipe Valve back in service.

F302/F3021 DRY PIPE VALVE
FIELD SERVICE NOTES & RECOMMENDATIONS
A. PROPER SEATING OF THE AUXILIARY CLAPPER ASSEMBLY
Whenever resetting the F302/F3021 Valve, and especially after replacing any internal components, it is
recommended that proper seating of the Auxiliary Clapper Assembly be checked by referring to Figure G on
Page 12. Doing so will help assure ease of resetting of the F302/F3021 Valve.
B. AUXILIARY CLAPPER ASSEMBLY
The materials for the Auxiliary Clapper Rod (17), Push Rod Screw (16), and Push Rod Screw Locknut (36) were
changed from brass to stainless steel in 1982, 1983, and 1988, respectively It is recommended that the brass
components be replaced by the newer stainless steel versions to increase durability. When replacing these
parts it will be necessary to replace the Auxiliary Clapper Rod O-Ring (18) and to lubricate the Auxiliary Clapper
Rod with Dow Corning FS3452 Flurosilicone Grease (43).
The material for the auxiliary Clapper Facing (22) was change from EPDM (black) to silicone rubber (red) in
1980. It is recommended that this component in EPDM (black) be replaced by the newer silicone rubber (red)
version to increase durability.
It is recommended that the Auxiliary Clapper Assembly (PSN 52-302-l-103) referred to under Replacement
Valve Parts be ordered, whenever changing any of the noted parts to the recommended materials.
C. WATERWAY CLAPPER ASSEMBLY
The Clapper Facing (6) was changed from a flat facing material to a molded ribbed facing material in 1981. It
is recommended that the flat Clapper Facing be replaced with the molded ribbed Clapper Facing. When replacing
a flat Clapper Facing with a molded Clapper Facing, the Clapper Washer (5) must be oriented with the tapered
side up, and a Belleville Spring (40) must be utilized with its recessed side facing up as shown in Figure B on
Page 3. The molded Clapper Facing is to be oriented so that the raised center portion faces up and the thin
raised rib faces down so as to seat within the groove in the Seat Ring (2).
D. CLAPPER LATCH
The Clapper Latch (14) for the 6 inch size F302/F3021 Valve was redesigned in 1986. The present “straight bar’
design, illustrated in Figure B, is a direct replacement for the older design which had an offset adjacent to the
contact area for the Push Rod Screw (18). It may be necessary to readjust the Auxiliary Clapper Assembly for
proper seating as shown in Figure G, when replacing the Clapper Latch.
E. AUXILIARY SEAT RING
As of 1986 an Internal Bore O-Ring (32) was added to the Auxiliary Seat Ring. Older F302/F3021 Valves cannot
be modified since the Auxiliary Seat Ring is not field replaceable.
F. AUTOMATIC DRAIN VALVE/VALVE TRIM
If the Automatic Drain Valve is found to be missing, replace it immediately. Also make certain that the
F302/F3021 Valve is properly trimmed per Figure F on PagelO. Doing so will help assure proper operation of
the F302/F3021 Valve in the event of a fire and will help assure ease of resetting of the F302/F3021 Valve.
The currently used Model F793 Automatic Drain Valve is a direct replacement for the Model F791 Automatic
Drain Valve that was used up to 1984.
G. SERVICE PARTS
It is recommended that arrangements be made to have on-hand the following items prior to servicing of an
F302/F3021 Valve:.Valve Replacement Parts Kit, Auxiliary Clapper Assembly, and Model F793 Automatic Drain
Valve.
WARNING
All replacement parts must be purchased through Grinnell Corporation or one of its authorized
distributors. The use of non-Grinnell manufactured replacement parts voids all warranties and
may void laboratory approvals. Failure to use Grinnell manufactured replacement parts may
result in failure of the Model F302lF3021 Dry Pipe Valves to properly operate.
