This is a direct-acting, spool-type, normally closed, electro-proportional, bypass/restrictive flow control valve. It controls flow to the priority port (port 3), with excess input flow bypassed to port 2. Once the bypass port is blocked, it functions as a two-port, electro-proportional, pressure-compensated flow control valve, regulate the flow from port 1 to port 3. Flow from port 3 is proportional to current applied to the solenoid.

  • Note: When used as a bypass flow control valve, and the priority port (port 3) is blocked by an external valve, it will result in port 2 being closed. Please ensure port 3 allows flow.
  • If you need other flow options, please contact the Winner sales department.
  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • Bypass flow does not work until the priority flow is satisfied.
  • Pressure at port 2 (bypass port) may be higher than pressure at port 3 (priority port).
  • Priority and bypass flow can be employed within the system's operating pressure range.
  • Working parts are heat-treated and high-precision ground to increase hardness for long life.
  • Regardless of how the inlet flow rate changes, the priority flow rate remains at a relatively constant level.
  • 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.
