ow Control Valve is a quick opening, differential type flood valve with a spring
loaded rolling diaphragm clapper. The Flow Control Valve can be used to facilitate manual
or automatic on/off control. As an on/off control valve it may be used on Deluge Systems,
Sprinkler Systems or to automatically fill tanks or reservoirs. The Viking Flow Control valve
is an integral part of the Viking Firecycle® System.
FEATURES
A. Field replaceable Diaphragms and Rubber Seated Clapper Assembly

Systems with water working pres-
sures above 175 PSI (1 207 kPa) may
require extra-heavy pattern fittings.
Viking Model H-1 Flow Control Valve
flanges are Ductile Iron ANSI B16.42
Class 150 with a maximum water
working pressure of 250 PSI. ANSI
B16.42 Class 150 flanges are NOT
compatible with ANSI Class 250 or
Class 300 flanges. To mate the
Model H-1 Flow Control Valve with
ANSI Class 250 or Class 300 flanges,
use the grooved-outlet style valve,
installed with listed groove/flange
adapters of the appropriate pressure
rating. For piping with grooved con-
nections, the grooved-outlet style
valve may be installed with listed
grooved couplings of the appropri-
ate pressure rating.

Accessories:
1. Model H Flow Control Conventional Trim package for use with the Flow Control Valve. The trim package includes all necessary
fittings, nipples and devices shown on the Model H Flow Control Valve Conventional Trim Charts. Trim Charts are provided in
trim packages and the Viking Engineering and Design Data Book. For optional pre-assembled modular trim packages, refer
to the Viking list price schedule or contact the manufacturer.
2. Firecycle Trim package for use when the Flow Control Valve is used on a Firecycle system. The trim package includes all
necessary fittings, nipples and devices shown on the Viking Firecycle Trim Charts.
3. Auxiliary Components are required for specific valve functions. For complete operating trim requirements refer to system data
for the system used.
NOTE: FOR PART NUMBERS OF ACCESSORIES, REFER TO VIKINGS LIST PRICE SCHEDULE.
4. INSTALLATION
When Valve Trim is used, to maintain listings and approvals, trim must be installed according to Viking Model H Flow Control Valve
Conventional Trim Charts specifically labeled Maximum 250 PSI Water Working Pressure. Refer to page 512 a-c. Order 250 PSI
(17.2 bar) trim separately.
A. General Instruction
1. Viking Flow Control Valves may be installed in any position.
NOTE: FOR POSITIONS OTHER THAN VERTICAL (SHOWN IN FIG. 1) MINOR MODIFICATION OF TRIM MAY BE REQUIRED
TO FACILITATE DRAINAGE FROM OUTLETCHAMBER OF THE FLOW CONTROL VALVE (CONSULT MANUFACTURER).
2. The valve must be installed in an area not subject to freezing temperatures or physical damage.
3. The valve must be trimmed according to current Viking Trim Charts and appropriate instructions for the system used. Trim
Charts are printed in the Viking Engineering and Design Data book, and are provided with trim packages.
4. The priming line must be connected upstream of the system water supply main control valve or to a constant source of water
at a pressure equal to the system water supply.
5. After the Flow Control Valve is set, operation of the Flow Control Valve requires the release of priming water from the priming
chamber. This may be by automatic or manual operation of the release system. Viking Flow Control Valves are compatible
with hydraulic, pneumatic, and electric release systems.
a: Hydraulic Release Systems: See Figures 3-5 for the maximum allowable elevation of hydraulic release piping above
the Flow Control Valve. If the maximum height of hydraulic release piping exceeds the limit shown in Figures 3-5, use a
Pneumatic or Electric Release System.
b: Pneumatic Release Systems: A Viking Pneumatic Actuator is required between the release system connection provided
on Flow Control Trim and pneumatic release system piping.
CAUTION: WHEN RELEASING DEVICES CAPABLE OF AUTOMATICALLY RESETTING ARE USED ON THE PNEUMATIC
RELEASE SYSTEM OF A FLOW CONTROL VALVE, VIKING MODEL E DELUGE VALVE CONVENTIONAL TRIM, COMPLETE
WITH PORV, IS REQUIRED.
NOTE: THIS ARRANGEMENT WILL NOT ALLOW THE FLOW CONTROL VALVE TO AUTOMATICALLY RESET.
c: Electric Release: Solenoid Valves, Release Control Panels, and Electrical Detectors must be compatible. Consult ap-
propriate listings and/or approval guides.
6. The Viking Flow Control Valve can be trimmed to automatically reset electrically or manually. For specific Trim arrangements
refer to System Data describing the system being installed.
NOTE: DO NOT INSTALL ANY RELEASING DEVICE, OR VALVE USED TO AUTOMATICALLY RESET THE FLOW CONTROL
VALVE, ON PNEUMATIC RELEASE PIPING.
For pneumatic release systems, any releasing valve or device used to automatically reset the Flow Control Valve must be installed
in the trim piping between the Pneumatic Actuator and the priming chamber outlet.
CAUTION: OPERATION OF VIKING FLOW CONTROL VALVES BY PRESSURIZING THE PRIMING CHAMBER WITH AIR OR
ANY OTHER PRESSURIZED GAS IS NOT RECOMMENDED OR APPROVED.
