  • Improved lifetime
    mean‑time-to-failure now 5,000,000 cycles.
  • Valve Status
    Electrical and visual indication of valve status
  • Fast acting
    20 ms to close (PV16)
  • Choice of Materials
    Available in aluminium or stainless steel
  • Sealing Options
    Choice of bellows or ‘O’ ring shaft sealing with aluminium bodies

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.
