The Edwards PVEK series valves are compact, light-weight electromagnetic vacuum valves suitable for use in vacuum pipeline systems down to 1x10⁻⁹mbar. A double wound coil combined with an electronic switching circuit ensures low energy consumption, low operating temperatures and extended operating life.
Bellows sealed, the PVEK solenoid operated right angle valves are available with either aluminium (A) or stainless steel (S) bodies, with an overall MTTF of up to 500,000 cycles.
