Zero Pressure Differential

Zero pressure differential solenoid valves, 3/8” to 2" NPT, for air, water, light oils, and steam. S20, S30, and S27 series with UL, CSA, CE, NEMA 4/4X, NEMA 7/9 explosion proof and NSF-61 approved for drinking water with options in normally closed and normally open versions, in 316 stainless steel, brass, and Nylon 6. Approvals vary by model

Direct-acting and piloted piston solenoid valves can operate at pressures as low as 0 psi in smaller sizes. For larger flows, Solenoid Valves Mart offers GC Valves high-flow models up to 2" pipe size for pressure differentials under 5 psi. Typical applications include:

  • Atmospheric and gravity-fed tank drains
  • Closed-loop cooling systems
  • Low-pressure gas, including UL Safety Rated valves
  • Irrigation systems.
