This is a pilot-operated, spool-type relief valve with normally closed modulating elements when connected to an external orifice, similar to a load-sensing relief circuit. The main stage functions as a bypass pressure compensator, regulating the priority flow within the circuit based on the specifications of the external orifice. Any input flow that exceeds the priority level is bypassed to the tank (port 2). If the pressure at the inlet (port 1) rises to the valve's predetermined setting, the valve will operate as a standard relief valve.

  • Back pressure at port 2 (tank port) is added directly to the valve setting in 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.
