This is an inverse direct-acting, poppet-type, pilot capacity proportional relief valve. The valve is spring biased closed to the highest pressure setting. Increasing the current supplied to the coil will proportionally decrease the pressure setting. The poppet will lift to allow flow from port 1 to port 2 when the pressure at port 1 overcome to the spring force minus the solenoid force, as determined by the analog input signal. The main stage of this valve is 8A-2 control cavity which can be paired with various Winner 8A-2 pressure control cartridge valves for a wide range of applications.

  • The maximum leakage at reseat is approximately 25 cc/min.
  • Reseat pressure exceeds 85% of cracking pressure.
  • Backpressure at the tank port (port 2) is directly added to the valve setting at a 1:1 ratio.
  • Dither frequency should be adjustable between 80-300 Hz (recommended frequency: 85 Hz).
  • High pressure setting with no command.
  • The factory pressure setting is configured for use with the main valve RV11A3CL.
  • In order to meet the pressure requirements and reduce setting inaccuracy, please contact the Winner sales department if you need a pressure setting and specify the main valve you intend to use.
  • Please contact us if pressure control beyond the specified range is required.
  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • 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.
