This is a dual pilot-to-open check valve. When pressure at port 2 or port 3 exceeds the spring bias pressure, the poppet is pushed from its seat and allowed from port 2 to port 1or port 3 to port 4. When sufficient pilot pressure is present at port 3 or port 2, the pilot piston operates to push the poppet, flow is allowed from port 1 to port 2 or port 4 to port 3. Pilot pressure needed at port 3 or port 2 to open the valve is directly proportional to the load pressure at port 1 or port 4. 

  • 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 high-quality 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.
  • 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.
