Valve Construction:

  • 303SS BODIES are welded onto a 303 Stainless Steel (303SS) PLUNGER TUBE and a 303SS TUBE PLUG is welded to the top of the PLUNGER TUBE.
  • Normally Open Stainless Steel PILOT VALVE ASSY consists of a 303SS PILOT POINT, 416SS PLUNGER, 303SS LIFT SPRING & 303SS SPRING RETAINER.
  • 303SS BODY NUT, which has a Teflon® Leakproof Pilot Valve Seat, is screwed into the BODY to form the 90° Angled configuration.


  • Installation: Valves must be mounted in horizontal pipe (outlet downward) with coil vertical, upright and on top.  A 40-mesh inline strainer is recommended ahead of the valve.
  • Maintenance:  As with any piece of equipment, reasonable inspection and maintenance of components should be periodically performed.  Frequently check operation, cleanliness and internal wear.  Any questions, consult factory.

     NOTE:    Gould  Solenoid  Valves are designed for Industrial-Commercial applications. Residential/Consumer applications will void the warranty. Questions ~ Call our Experts.
