This RC series valve is Winner’s patent, pilot-operated, poppet-type with a reverse check valve function.  When the pressure at port 1 exceeds the pressure setting of proportional valve, the poppet opens and allows flow from port 1 to port 2. The check valve section allows flow from port 2 to port 1. This valve features a special poppet construction, maintaining essentially zero leak (the cracking pressure of the check valve is approximately 2 bar) when port 1 to port 2 is closed. If extremely low pressure (approximately 0.3 bar) is required as anti-cavitation from port 2 to port 1, the leakage from port 1 to port 2 when closed should be considered. For further technical information, please contact the Winner sales department.

  • Will accept maximum pressure at port 2, suitable for use in a cross-port relief circuit.
  • The maximum leakage is approximately 15 cc/min at 70 bar (1000 psi).
  • Check valve cracking pressure from port 2 to port 1 is 0.3 bar (5 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.
