PV16EKA
The Edwards PVEK 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 PVEK solenoid operated valves are available with either aluminum (A) or stainless steel (S) bodies, and in right-angle (PVEK) and in-line (IPVEK) versions, with an overall MTTF of up to 130,000 cycles.
