Overview

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 5000000 cycles for both bellows and ‘O’ ring sealed versions providing long intervals between services.

Technology

The PVPK valves are offered with a choice of either aluminum (PVKA) or stainless steel (PVKS) bodies. Both versions are available with bellows sealing with grease free vacuum wetted ‘O’ rings to deliver low contamination levels in sensitive applications. The aluminum bodied valves have the option of an ‘O’ ring sealed shaft providing a low cost valve ideal for high cycling duties, making them suitable for industrial applications.
 
The valves are designed for long life duties, with a MTTF of 5000000 cycles for both bellows and ‘O’ ring sealed versions providing long intervals between services.
 
A single microswitch is incorporated as standard to give electrical indication of valve status, whilst visual indication of valve position is also provided. Twin microswitch versions are available on some models for OEM applications.
The actuator can easily be turned through 90 degrees to suit system design and the valve can be mounted in any position.
