This is a vent-to-open, balanced poppet, normally closed logic element valve. When port 4 (vent port) is blocked, the poppet remains closed, allowing flow between port 1 and port 2. The valve will open and allow flow between port 1 and port 2 only when port 4 is vented and sufficient pressure is applied to port 3 to shift the valve. Port 4 allows hydraulic circuit designers flexible usage in various applications. 

  • We recommend using a pilot pressure above 30 bar (450 psi) at port 3 when ports 1 and 2 are at 350 bar (5000 psi). This ensures quick shifting across various pressure and flow conditions.
  • The maximum leakage is approximately 0.7 cc/min at 350 bar (5000 psi).
  • All ports will withstand up to 350 bar (5000 psi).
  • 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.
