This is a direct-acting, spool-type reducing valve that acts as a restrictive compensator. It reduces high pressure at port 2 to a consistent and lower pressure at port 1.

  • 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.
  • When the pressure drop of LP-2A-30 is 14 bar, the orifice is not able to satisfy customer's demand for higher flow. We recommend selecting PD-2A-3J, which has a larger orifice and can be adjusted to a higher pressure drop to allow greater flow. 
  • The inlet pressure of all spring specifications is up to 350 bar (5000 psi).
  • Pressure at port 3 adds directly to the valve setting at a 1:1 ratio.
  • 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.
