Series BLSF fire safe ball valves ensure the equipment continues to perform in the event of a fire.
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.
Key features of Series BLSF fire safe ball valves include CR8M (316 stainless steel) or WCM (black cast steel) construction; sizes from 15 mm to 100 mm; 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.
