The Edwards IPVEK series valves are compact, light-weight electromagnetic vacuum valves suitable for use in vacuum pipeline systems down to 1 x 10-9 mbar. A double wound coil combined with an electronic switching circuit ensures low energy consumption, low operating temperatures and extended operating life.

Bellows sealed, the IPVEK solenoid operated in-line valves are available with either aluminum (A) or stainless steel (S) bodies, with an overall MTTF of up to 500,000 cycles.
