Purchase Specifications
The Fire Pump Suction Control Valve shall modulate to main-
tain a minimum pressure at the pump suction regardless of
system demand. It shall control the pump discharge in rela-
tion to the suction head available, and shall not allow suction
head pressure to fall below a pre-set minimum.
It shall be actuated by line pressure through a pilot control sys-
tem which allows rapid response to changing pressure condi-
tions without line surges. The pilot control shall be remote
sensed to the pump suction head pressure.
The main valve shall be of the hydraulically-operated, pilot-
controlled, diaphragm-type, globe or angle valve. It shall have
a single removable seat, a delrin-sleeved guided stem and a
renewable resilient synthetic rubber disc with a rectangular
cross section, contained on three and one-half sides by a disc
retainer and disc guide. No external packing glands shall be
permitted and the diaphragm shall not be used as a seating
surface. The pilot control shall be a direct-acting, adjustable,
spring-loaded, diaphragm-type valve designed for modulating
service to permit flow when controlling pressure exceeds
spring setting.
A device indicating the percent at which the valve is open or
closed shall be supplied on the assembly, together with a sed-
iment evacuator and dampening device.
The valve shall be designed to allow for repair and servicing
without removing the valve body from the line.
The valve shall be Factory Mutual Approved. It shall be the
MODEL 50B-5KG FIRE PUMP SUCTION CONTROL VALVE
as manufactured by Cla-Val, Newport Beach, California.
