This is a pilot-to-open check valve. When pressure at port 2 exceeds the spring bias pressure, the poppet is pushed from its seat and allowed from port 2 to port 3. When sufficient pilot pressure is present at port 1, the pilot piston operates to push the poppet, flow is allowed from port 3 to port 2. Pilot pressure needed at port 1 to open the valve is directly proportional to the load pressure at port 3. Pressure at port 2 affects pilot-to-open pressure on a 1:1 ratio.Hardening processes and precision machining for long life and low leakage.

  • This valve can prevent the drifting of loads and securely locks pressurized loads, also provides protection to a pipe rupture or hose break.
  • Internal components are made of highquality materials, processed heat treatment and precision grinding to achieve excellent wear resistance and protection against contamination for long-lasting durability.
  • Virtually leak-free. If the valve causes the load to drift, the seat may be damaged by contamination. Please replace the valve immediately.
  • Pilot-to-open check valves are not intended to be used as motion control valves. If motion control is required in a circuit, please choose counterbalance valves.
  • Industry common cavity.
  • This valve is suitable for mounting in regenerative circuits or for controlling motors or cylinders.
  • Available bias springs for back pressure applications flexibility.
  • Consider using a check valve instead of a counterbalance valve if overrunning loads or controlled release speed are not critical in the application.
  • Based on the same flow rate, installation position, flow path, and cavity, three-port pilot-to-open check valves and three-port counterbalance valves are interchangeable. However, please note that there are functional differences and variations in external dimensions between them.
  • External components are WINNERcoat® Zinc-Nickel Plating for 1000 hours salt spray test according to DIN EN ISO 9227. Also, some ordering code with letter "P" at the end is stainless steel external components. The ordering code with letter "S" at the end is all components of cartridge valve are made of stainless steel for special requirements such as deep sea, marine or water based hydraulic.
  • Winner guarantees that all products performance a 100% functional test before shipment.
