This is a balanced poppet, normally open, logic element valve. The valve remains closed until the pilot pressure applied at port 3 exceeds the valve setting determined by the integral pilot relief stage. The poppet shifts, blocking the flow path between port 1 and port 2. 

  • The maximum leakage is approximately 0.7 cc/min at 350 bar (5000 psi), with a very low leakage rate between port 1 and port 2.
  • All ports can withstand up to 350 bar (5000 psi).
  • When the pilot pressure drops to setting approximately 85 % of cracking value, the valve will return to the spring biased closed position.
  • Back pressure at port 4 (drain) adds directly to the relieving 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.
  • Recommendation of minimum pilot pressure required to shift valve is 28 bar (port 3).
