The 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 500,000 cycles.

Features and Benefits

  • Enclosure rating to IP55
  • Grease free vacuum
  • MTTF up to 500000 cycles
  • Circuit protected against transient low voltages
  • Improved circuit board reliability
  • User friendly plug and socket connections to IP65
