The Edwards range of in-line single acting cylinder, spring return pipeline valves are designed for high speed actuation from standard pneumatic lines, and are offered in sizes NW16, 25, 40 and 50. They are available with aluminium or stainless steel bodies with either O-ring (shaft seal, aluminium only) or bellows sealed.
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.
mean‑time-to-failure now 5,000,000 cycles.
