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 drawn in 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.
