Load reactive, load control valves have check and fixed throttle characteristic. 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, the pilot activates fixed throttle component to allow the flow from port 1 to port 2 and the flow rate is controlled by pilot pressure at port 3.

  • Setting should be 1.3 times maximum load induced pressure.
  • Reduce valve setting and release load by turning screw clockwise.
  • The pressure setting will increase when back pressure at port 2. PS=(PR+1)xBP；PS=Pressure Setting, PR=Pilot Ratio, BP=Back Pressure
  • The valve is capable of fully releasing pressure.
  • 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.
  • Counterbalance valve and load control load reative valve are ideal for mounting directly near or in cylinder, hydraulic motor and rotary actuator as protection to increase the safety of the circuit.
  • The valve is functionally a 3 ports counterbalance valve (CB). It seats as a poppet valve and modulates as a spool valve.
  • 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.
