Description



Normally Closed Diaphragm Solenoid Valve

  • 120V
  • 1/2in
  • 150PSI
  • Brass body, Buna N seal
  • Application: Water, air, noncorrosive and nonexplosive
    liquids
  • Rated 200º F fluid, 120º F ambient
  • Repair kit available 
  • Operation: When energized, the plunger is pulled to the
    top plug, thus opening the small “pilot port” in the center
    of the diaphragm plate. This releases the pressure on top of
    the diaphragm allowing incoming pressure to lift it off the
    large center port. When de-energized, the solenoid plunger is
    pushed from the top plug by the kick-off spring and closes
    the pilot port. Fluid passes through the diaphragm bleed hole
    until pressure is equalized on both sides of the diaphragm to
    shut off the large port
