This is a direct-acting, poppet-type reducing valve, ideal for stable and precise control of secondary pressure within a circuit. It allows flow from port 2 to port 1 until the pressure at port 1 overcomes the spring bias. The poppet lifts to block flow from port 2 to port 1, and maintains consistent pressure at port 1, regardless of pressure changes at port 2. 

  • Port 2 and port 1 to port 3 without internal leakage.
  • Pressure reducing for a long time, unnecessary provide oil by pump.
  • Please pay attention when using this valve in a dead-head application (no flow from port 1 to port 2) because it is without relieving function. The pressure may continue increase obviously because of the very low leakage at the reduced pressure side of the circuit. The pressure at port 1 will not stop at the pressure setting of the spring, it will gradually increase toward port 2 according to the flow.
  • This valve is almost zero leakage. To prevent pressure changes at port 1, we suggest increasing port 1 capacity of cavity. If you have any question, please contact the Winner sales department.
  • For applications requiring a relief function, please refer to the PG-11A-30-Y-Z.
  • The inlet pressure of all spring specifications is up to 350 bar (5000 psi).
  • Working parts are heat-treated and high-precision ground to increase hardness for long life.
  • 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.
