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
