2/2 way Plunger-Solenoid Valve with separating diaphragm

Last updated: May 21, 2020  |  244 จำนวนผู้เข้าชม  |  Article

Type 117 is a normally-closed direct-actingplunger-type solenoid valve with PTFE-coated diaphragm. The diaphragm isolates the fluidfrom the solenoid system. When deenergized (in circuit function A)the valve is closed by spring action. When energized, the solenoid armature is drawnin 2/2 way, G 1/8, UNF 1/4-28 FluidControl Systems against a spring to open the valve. The solenoid epoxy encapsulation efficiently dissipates the heat generated by the coil.

  • Compact design
  • Low electrical power consumption
  • Short response times
  • Hermetically sealing isolating diaphragm
  • Non-metallic valve internals
