This is a direct-operated, spool type, bypass/ pressure compensated priority flow control valve. Regardless of system pressure or load, the valve maintains a constant flow from port 1 to port 3. Input flow supplied to port 1 in excess of the priority output at port 3 is bypassed to port 2. The regulated flow decreases with clockwise rotation of the adjusting screw. Flow from port 3 to port 1 is limited by the diameter of the control orifice and is not pressure compensated.

  • Note: It can be used as a priority-type flow regulator or a restrictive-type 2-way regulator when the bypass port (port 2) is blocked.
  • 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.
