This valve is a pilot-operated, balanced poppet relief valve with an integral 8A-2 pilot control cavity, designed for use with any 8A-2 pressure control cartridge valve. When the pressure at port 1 overcomes the pilot control setting, it opens port 2 and allows metered flow to regulate the pressure. The pressure differential between port 1 and port 2 is determined by the settings of the pilot control. It is commonly paired with Winner pilot-operated proportional relief valves.

  • Maximum pressure can be accepted at port 2, suitable for use in cross port relief circuits but spool leakage should be considered.
  • W spring is suitable for higher pressure drop applications.
  • 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.
