Vented, load reactive load control valves combine check and relief features. When load pressure at port 2 rises over the check cracking pressure, check valve will allow free flow from port 2 to port 1. Meantime, relief valve with pilot assistant, direct-acting allows flow from port 1 to port 2. Pilot ratio controls flow rate of the effective setting of the relief valve. Due to the vent at port 4 connect to spring chamber, backpressure at port 2 can be excluded when pressure setting.

  • Setting should be 1.3 times maximum load induced pressure.
  • Turn the screw fully clockwise to reduce the load setting. This action will adjust the spring range to its minimum value: 70 bar for spring code 'H' and 140 bar for code 'J'.
  • Function of this valves is same with 4-port counterbalance valves (CB). The seat as a poppet type to make sure no leakage when it is stationary; and as spool type to control flow rate accurately and stably when it is operation.
  • This valve is capable of full relief.
  • Turn screw clockwise to reduce setting and release load.
  • These valves exhibit a wider modulation range for flow control compared to pure poppet designs. The extended stroke enables the integration of a unidirectional damping mechanism, facilitating smoother opening and swift closure of the valve.
  • Counterbalance valve and load reactive load control valve are ideal for mounting directly near or in cylinder, hydraulic motor and rotary actuator as protection to increase the safety of the circuit.
  • Winner® offers a wide range of products, including counterbalance valves, pilot-to-open check valve and load control valve can be flexible application in circuits under the same cavity, flow path and pilot port at port 3.
  • 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.
