This is a pilot-stage, direct-acting, spool-type, double lock directional valve. It blocks flow between ports 2 and 1 until the manually knob is turned against the bias spring, allowing flow between ports 2 and 1. This valve is ideal for pilot flow applications in Winner's 8A-2 cavity and pairs with Winner's pilot-operated main-stage valves.

  • Recommended flow direction: inlet at port 2, outlet at port 1.
  • Configuration Z=R Type: Turn the knob clockwise to achieve the override function. The knob will automatically return to the starting position when released.
  • Configuration Z=RA Type: Turn the knob counterclockwise to the locked (fixed) position to achieve the override function. Turn the knob clockwise to release, and the knob will return to the starting position.
  • Configuration Z=RB Type: This configuration combines the operations of the R type and RA type to achieve the override function by turning the knob either clockwise or counterclockwise. Please refer to the R type and RA type instructions.
  • Note: These operations are for emergency use only and are not intended for load-holding applications.
  • 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.
  • The maximum leakage is approximately 0.7 cc/min at 350 bar (5000 psi).
  • 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.
