This valve is direct-operated, fully adjustable needle flow control valve with reverse flow check. Output flow can be varied from fully closed to the maximum orifice diameter. Flow is non-pressure-compensated. Free flow is allowed from port 2 to port 1, regardless of valve adjustment, by when pressure overcomes the spring bias of the valve check function.

  • The rated flow is a reference value, actual flow depends on the pressure drop.
  • 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.
