The range of single acting cylinder, spring return pipeline valves is designed for high speed actuation from standard pneumatic lines, and are offered in sizes NW10, 16, 25, 40 and 50.
They are available with aluminium or stainless steel bodies with either O-ring (shaft seal Aluminium only) or bellows seal.
The valves are designed for long life duties, with a MTTF of 5,000,000 cycles for both bellows and ‘O’ ring sealed versions providing long intervals between services.
