This is an unbalanced poppet logic element valve with an integral shuttle, allowing the higher pressure from either port 1 or port 2 to serve as a pilot source. When a pilot 2-way valve is installed in the 8A2  cavity in the closed position, the logic element remains in the closed position. When the pilot valve is open, the logic element will open if there is a sufficient combination of pressures at port 1 and port 2 to overcome the spring force. To maintain closure, the combined force (force generated at port 3 plus spring force) must exceed the forces at port 1 and port 2.

  • All ports can withstand up to 350 bar (5000 psi).
  • Area ratio of A3 to A1 is 1.8:1.
  • Area ratio of A3 to A2 is 2.25:1.
  • 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.
