This is a direct-acting, balanced spool, 4-way 2-position. It allows flow from port 3 to port 2 and from port 4 to port 1 until the knob is turned against the bias spring, allowing flow from port 3 to port 4 and from port 2 to 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.
  • 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".
