This is a direct-acting, poppet type, 3-way 2-position directional valve, intended for use as a load holding device in hydraulic circuits requiring manual operation and low internal leakage. The valve allows bidirectional flow from port 2 to port 1 until the knob is turned against the bias spring. This action blocks the flow path between port 2 and port 1 in both directions and opens the flow path from port 3 to port 2. All ports are open during the transition position.

  • 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.
  • Please refer to the J.990.115.E directional valve manual override knob instructions.
  • The maximum leakage is approximately 0.7 cc/min at 350 bar (5000 psi).
  • Working parts are heat-treated and high-precision ground to increase hardness for long life and essentially zero leakage.
  • A variety of seal kit materials for different applications, see seals information under Technical Reference.
  • This valve is designed to hold load pressure at port 3 only. The detent mechanism in the manual override is intended for temporary actuation.
  • 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.
