This is a direct-acting, spool-type relief valve intended for use as a pressure-limiting device to protect hydraulic systems from pressure transients. The valve blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to overcome the valve setting, allowing relief flow to port 2 (tank) while throttling the flow to restrict the pressure rise. It is ideal for low-pressure applications, providing good control with a constant flow. Additionally, it operates very quietly when applied to low-flow or unstable hydraulic systems, but spool leakage should be considered.

  • Back pressure at port 2 (tank port) is added directly to the valve setting in a 1:1 ratio.
  • This valve is not proper to use in load holding applications due to spool leakage.
  • 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.
