This is a pilot-operated, spool-type reducing valve, designed 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 spool shifts to block flow from port 2 to port 1, and maintains consistent pressure at port 1, regardless of pressure changes at port 2.

  • Pressure at port 3 adds directly to the valve setting at a 1:1 ratio and should be kept below 210 bar (3000 psi).
  • Please be aware of the pressure differential between the inlet port and the reducing port to select a spring with the proper adjustment range. For any questions, please contact the Winner sales department.
  • If pilot flow is not required, please refer to PD-19A-30-Y-Z
  • When considering dynamic response, direct acting valves are a more suitable choice as they do not rely on pilot pressure to operate, resulting in quicker valve opening and closing times.
  • 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.
