Process Systems introduces a new range of fire safe ball valves designed to function under extreme heat conditions.
Series BLSF fire safe ball valves from Process Systems will ensure the equipment continues to perform in the event of a fire. The ball valves can withstand extreme heat as per the American Petroleum Institute code ANSI/API 607 Sixth Edition.
Manufactured to the highest standard and competitively priced, Series BLSF fire safe ball valves come in multiple options including manual lever or gear box, pneumatic double acting or spring closed, and electric ON/OFF or electric spring closed. The valves are flanged ANSI 150/ANSI 300 and suitable for a wide range of industrial and environmental applications.
Key features of Series BLSF fire safe ball valves include CR8M (316 stainless steel) or WCM (black cast steel) construction; sizes from 15mm to 100mm; dual pattern ISO 5211 mounting pad with square shaft; supplied standard with lever operation - pneumatic or electric actuator can be quickly mounted without bracket or adaptor; floating ball design providing pressure assisted sealing and temperature/wear compensation; precision machined, and mirror finished ball for bubble tight shutoff with less operating torque and temperature compensation.
Features also include PTFE and graphite seats; multiple layers of Chevron shaped stem seals featuring two preloaded Belleville washers that automatically adjust for wear, pressure and temperature fluctuations; Viton (FKM) O-ring on the valve stem enhancing stem seal and stem alignment to give long service; blow-out proof stem for maximum safety; and spring loaded stem-to-ball and stem-to-body anti-static device as standard.
