The bellows seated PVEK solenoid operated valves are available with either aluminium (A) or stainless steel (S) bodies. We offer both right angle (PVEK) and in-line (IPVEK) version of the valve to give you more options when you design your vacuum system. These valves are amongst the most compact and lightweight solenoid valves available.


The Edwards PVEK Solenoid Operation Isolation valves offer all of these advantages:

  • Transient high power for opening – electronically switched

  • Low energy consumption in the 'hold open' position

  • Enclosure rating to IP55

  • Grease free vacuum

  • MTTF up to 500000 cycles

  • Circuit protected against transient low voltages

  • Improved circuit board reliablity

  • User friendly plug and socket connections to IP65

The twin coils combined with an electronic switching circuit will enable high power to be applied for a very short period to open the valve, the power then being automatically reduced to low levels to hold the valve in the open position.

A reed switch is included to indicate open and closed conditions.

Improved circuit board design to indicate open and closed conditions.

Improved circuit board design has achieved enhanced life expectancy up to 5 times that of the previous design. Overall MTTF for the valves is up to 500000 cycles.
