GENERAL DESCRIPTION
The 4 and 6 inch (100 and 150 mm),
Model F470H Horizontal Multimatic
Deluge Valves are differential latch
type valves designed for fire protection
system service. They are used as
“automatic water control valves”in del-
uge, preaction, and foam-water fire
protection systems.The F470H Valves
alsoprovidefor actuationoffirealarms
upon system operation.
Operation of an F470H Valve is pro-
vided by an actuation (detection) sys-
tem that is separate from the normally
dry system piping. Trim configuration
options for automatic operation of the
F470H include wet pilot actuation, dry
pilot actuation, and electric actuation.
The various trim arrangements also
provide for local emergency (manual)
release of the F470H Valves.

on steel.
The nominal pressure losses versus
flow are shown in Graphs A-1 and A-2.
Theapproximatefrictionlosses,based
on the Hazen and Williams formula
and expressed in equivalent length of
Schedule 40 pipe with C = 120, is 12
feet for the 4 inch (100 mm) valve size
and 30 feet 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.

Wet Pilot Actuation
(Figure D, Items 1 through 38)
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
(15 mm) Schedule 40 steel pipe. The
pilot line is connected to the “Wet Pilot
Detection”connection shown in Figure
D. Minimum clearance dimensions for
the Wet Pilot Actuation Trim are shown
in Figure C.
Wet pilot sprinklers are to be minimum
1/2 inch (15 mm) orifice listed or ap-
proved automatic sprinklers. Manual
Control Stations are to be either the
ModelF180orF184describedinTech-
nical Data Sheet TD121.
The maximum height of a wet pilot line
above the F470H Valve must not ex-
ceed the limitations given in Graph B
as a function of the minimum water
supply pressure to the F470H Valve
and the length of the pilot line to the
most remote pilot sprinkler.
Provision must be made for installing
a 1/2 inch (15mm) orifice, Inspector’s
Test Connection at the most hydrauli-
cally demanding location of a wet pilot
line (usually adjacent to the highest
and most remote wet pilot sprinkler or
manual control station).
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 F470H Valve and the
equivalent length of fittings plus hori-
zontal pipe from the F470H Valve to
the location.Then, using Graph B, de-
termine the minimum system supply
pressurerequired for theelevationand
equivalent length of pipe at each loca-
tion. Interpolate between the equiva-
lent length plots as necessary. The lo-
cation requiring the highest system
supply pressure is the most hydrauli-
cally demanding location for the wet
pilot line. (Reference: In no case
should the required system supply
pressure exceed the 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 F470H 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
WetPilotLinesmustbemaintainedat
a minmum temperature of 40°F/4°C.
Itisrecommendedthatinternallygal-
vanized pipe and cast iron fittings be
used for wet pilot lines.
Dry Pilot Actuation
(Figure D, Items 1 through 38 plus
Items D1 through D15)
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
(15 mm) steel pipe. The pilot line,
which is to be pressurized with air or
nitrogen, is connected to the “Dry Pilot
Detection”connection shown in Figure
D. Provision must be made for a 1/2
inch (15 mm) orifice, Inspector’s Test
Connection at the most remote loca-
tion from the F470H Valve. Minimum
clearance dimensions for Dry Pilot Ac-
tuationTrimareshowninFigureC.
The Dry Pilot Actuation Trim is pro-
videdwith a listedandapproved Model
B-1 Dry Pilot Actuator, which is de-
scribed in Technical Data Sheet
TD117W.The Actuator is rated for use
at a maximum pilot service pressure of
50 psi (3,4 bar) and a maximum water
supply service pressure of 175 psi
(12,1 bar).
Operation of a pilot sprinkler or open-
ing of a manual control station, re-
leases pneumatic pressure from the
pilot line.In turn, the Dry Pilot Actuator
opens resulting in a rapid pressure
drop in the Diaphragm Chamber of the
F470H Valve, and the force differential

TD112.
•Model F328 Nitrogen Mainte-
nance Device (high pressure re-
ducing type), refer to Technical
Data Sheet TD113.
NOTES
The dewpoint of thepilot line air pres-
sure must be maintained below the
lowest ambient temperature to which
the dry pilot actuation system will be
exposed.Accumulation of water in the
pilot line connection to the Actuator
will lower the air pressure at which
the Actuator will open and possibly
prevent proper operation. Also, intro-
ductionof moistureinto thepilotlines
exposed to freezing temperatures can
createan icebuildupwhichcouldpre-
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
therequiredvalue.Thedesiccantdryer
with mounting accessories described
inTechnicalDataSheetTD135issuit-
able for use with a maximum inlet
pressure of 150 psi (10,3 bar) and for
drying system air down to a dewpoint
of less than -20°F/-29°C at a pressure
of 45 psi (3,1 bar).
It is recommended that an F328 Ni-
trogenMaintenanceDevicebeutilized
in dry pilot actuation system applica-
tions where the dewpoint must be
maintained below -20°F/-29°C. See
Technical Data Sheet TD113.
Itisrecommendedthatinternallygal-
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 as the unit described in Technical
Data Sheet TD210, is suitable for the
service. The recommended pressure
settings are as follows:
• Low pressure alarm setting at
approximately 6 psi (0,4 bar)
below the minimum pilot line
service pressure requirement
shown in Graph C.
• Fire alarm setting at approxi-
mately 15 psi (1,0 bar) below
the minimum pilot line service
pressure requirement shown
in Graph C.
The Pressure Relief Valve (Ref. Item
D5 - Fig. D) is factory set to relieve at
apressureofapproximately45psi(3,1
bar); however, it may be field adjusted
to a lower pressure, if required.
Electric Actuation Trim
(Figure D, Items 1 through 38 plus
Items E1 through E5)
The Electric Actuation Trim is required
for electric operation of the F470H
Valve by a detection system consisting
of electrical devices such as heat sen-
sitive thermostats, smoke detectors,
and/or electric manual pull stations.
Information on the various types of So-
lenoid Valves that may be used with
this trim package is given in Technical
Data Sheet TD119. A listed and ap-
proved, 24VDC Solenoid Valve for
non-hazardous locations is supplied
as standard. Minimum clearance di-
mensions for the Electric Actuation
Trim are shown in Figure C.

OPERATING PRINCIPLES
The Model F470H Horizontal Multi-
matic Deluge Valve is a differential
latch type valve which depends upon
water pressure in the Diaphragm
Chamber to hold the Clapper closed
againstthewatersupplypressure.The
nominal trip ratio is 2.5 to 1, i.e., the
F470H Valve operates (opens) when
the pressure in the Diaphragm Cham-
ber is reduced to approximately 40
percent of the water supply pressure.
When the F470H Valve is set for serv-
ice, the Diaphragm Chamber is pres-
surized through the trim connections
from the inlet side of the system’s main
control valve, for example an O.S.&Y.
gate valve or butterfly valve (Ref. Fig-
ureC).Openingofanactuationdevice,
for example the solenoid valve in the
Electric Actuation Trim (Ref. Fig. D),
releases water from the Diaphragm
Chamber faster than it can be replen-
ished through the 1/8 inch (3,2mm)
Restriction in the Diaphragm Chamber
Supply Connection. This results in a
rapid pressure drop in the Diaphragm
Chamber and the force differential ap-
pliedthroughthe ClapperLatchtohold
the Clapper down in the set position is
reduced to below the valve trip point.
The water supply pressure then forces
the Clapper open permitting water to
flow into the system piping, as well as
through the Alarm Port to actuate the
system alarms.
When the system main control valve is
closed to stop waterflow into the sys-
tem, the Clapper, by design, remains
open until it is manually reset.
INSTALLATION
NOTES
Proper operation of the Model F470H
Horizontal Multimatic Deluge Valves
depends upon their trim being in-
stalled in accordance with the in-
structions given in this Technical
Data Sheet. Failure to follow the ap-
propriate trim diagram may prevent
the F470H Valve from functioning
properly,aswellasvoidlistings,ap-
provals, and the manufacturer’s war-
ranties.
The F470H Valve must be installed in
a readily visible and accessible loca-
tion.
The F470H Valve, associated trim,
and wet pilot lines must be main-
tained at a minimum temperature of
40°F/4°C.
Heat tracing of the F470H 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 F470H Horizontal Multi-
maticDelugeValveistobeinstalledin
accordance with the following criteria:
1a. Flange mounting fasteners are to be
tightened uniformly using a cross-
draw sequence. Fastener specifica-
tions are to be as required by the

12. Unused pressure alarm switch con-
nections must be plugged.
13. The Pressure Relief Valve provided
with the Dry Pilot Actuation Trim is
factory set to relieveat a pressure of
approximately 45 psi (3,1 bar),
which can typically be used for a
maximum normal dry pilot actuation
system pressure of 40 psi (2,8 bar).
The Pressure Relief Valve may be
reset;however, itmust be beresetto
relieve at a pressure which is in ac-
cordance 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

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.It isalsorecommendedthatfire
protection systems be inspected by a
qualified Inspection Service.
NOTES
The operational test procedure, water-
flow pressure alarm test procedure,
and low pressure alarm test proce-
dure will result in operation of the
associated alarms. Consequently, no-
tification must first be given to the
owner and the fire department, cen-
tral 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
which it controls, permission to shut
down the effected fire protection sys-
tems 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 F470H Valve
(i.e., opening of the F470H Valve as
during a fire condition) should be veri-
fied at least once a year as follows:
1. Ifwatermustbepreventedfromflow-
ing beyond the riser, perform the fol-
lowing steps.
a. Close the Main Control Valve.
b. Open the Main Drain Valve.
c. Open the Main Control Valve
oneturn beyond theposition at
which water just begins to flow
from the Main Drain Valve.
d. Close the Main Drain Valve.
2. Determine the type of actuation/de-
tection system, and operate the
F470H Valve accordingly.
NOTE
Be prepared to quickly perform
Steps3,4,and5,ifwatermustbe
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.

6. Reset the F470H 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
prior to the F470H Valve being reset,
the Diaphragm should be inspected
and replaced if there are any signs of
deterioration due to age or chemicals
in the water.
NOTE
If the water supply contains chemi-
cals which tend to attack an EPDM
type rubber, the frequency of the Dia-
phragm inspection should be in-
creased as appropriate.
Worn or damaged parts must be re-
placed and the F470H Valve must be
reassembled in accordance with Fig-
ure B. The Cap Screws securing the
Diaphragm and Handhole Covers
should be uniformly tightened using a
cross-draw sequence.

uge releasing panel) in accordance
with the manufacturer’s instructions
to energize the solenoid valve.
4. Verify that the flow of water from the
Solenoid Valve drain connection in-
creases to a full flow.
5. Verify that the Diaphragm Chamber
pressure has decreased to below
25% of the water supply pressure.
6. Reset the electric detection system
in accordance with the manufac-
turer’s instructions to de-energize
the solenoid valve. Check the Sole-
noid Valve drain for leaks.Any leaks
must be corrected before proceed-
ing to the next step.
7. Slowly open the Main Control Valve.
Close the Main Drain Valve as soon
as water discharges from the drain
connection. Observe the Automatic
