The Fire Pump Pressure Relief Valve shall modulate to relieve excess
pressure in a fire protection system, maintaining constant pressure in the
system regardless of demand changes. It shall be pilot controlled and
back pressure shall not affect its set point. It shall be actuated by line
pressure through a pilot control system and open fast in order to maintain
steady system pressure as system demand decreases. It shall close
gradually to control surges and shall re-seat drip-tight within 5% of its pres-
sure setting.
The main valve shall be of the hydraulically-operated, pilot-controlled,
diaphragm-type, globe or angle valve. It shall be equipped with a teflon-
coated anti-cavitation seat, a grooved stem guided at both ends, and a
resilient disc with a rectangular cross section, being contained on 3-1/2
sides. 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 mod-
ulating service to permit flow when controlling pressure exceeds spring
setting. This valve shall be UL Listed and Factory Mutual approved. It
shall be the Model 50B-4KG1KOL (globe) or Model 2050B-4KG1KOL
(angle) Pressure Relief Valve as manufactured by Cla-Val Newport Beach,
California.
*Special Note:
The Model 50B-4KG1KOL/2050B-4KG1KOL Pressure Relief Valve is
available with 300# ANSI inlet flange and 150# ANSI outlet flange for high
pressure systems where 300# flange connections are required, to allow for
adapting of a discharge cone (generally supplied with 150# flange) to
accommodate "atmospheric break" at relief valve discharge.
This relief valve, with 300# / 150# flanges is available on special order, and
is UNDERWRITERS LABORATORIES LISTED AND FACTORY MUTUAL
APPROVED.
