This is a pilot-operated, balanced poppet relief valve. It blocks flow from port 1 (inlet port) to port 2 (tank port) until a sufficient pressure applied to port 1 to pilot-to-open the poppet, opening a flow path from port 1 to port 2. This valve operates quietly and has extremely low leakage.

  • Maximum pressure can be accepted at port 2, suitable for use in cross port relief circuits.
  • The maximum leakage is approximately 0.7 cc/min at 70 bar (1000 psi).
  • This valve features a balanced poppet design to reduce cavitation and manifold erosion during high pressure drop applications.
  • Pilot port is protected for contamination resistance by a stainless-steel filter screen.
  • Back pressure at port 2 (tank port) is added directly to the valve setting in a 1:1 ratio.
  • Working parts are heat-treated and high-precision ground to increase hardness for long life and essentially zero leakage.
  • A variety of seal kit materials for different applications, see seals information under Technical Reference.
  • Winner's cartridges pressure rating tested to the standard of the NFPA specification T2.6.1 and the fatigue rating's assurance and verification level is "90/90".
  • WINNERcoat® Zinc-Nickel Plating is salt spray tested in accordance with DIN EN ISO 9227 for up to 1000 hours.
  • Winner guarantees that all products performance a 100% functional test before shipment.
