This is a pilot-operated, balanced piston, ventable relief valve. When the pressure at port 1 overcomes the pilot control setting, it pilot-to-open port 2 and allows throttling flow to regulate the pressure. The vent port connects the main piston to the pilot stage, allowing remote control by other pilot or 2-way valves. This valve has an external drain (port 4) connected to the spring chamber, making it insensitive to back pressure at port 2.

  • The maximum leakage is approximately 66 cc/min at 70 bar (1000 psi).
  • Pressure at port 4 is added directly to the valve setting in a 1:1 ratio, and must be less than 350 bar (5000 psi).
  • 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.
