Without pilot assistant counterbalance valves (overcenter valves) provides static and dynamic control of loads to prevent overruning of hydraulic actuators such as cylinders or motors. The check section allows free flow from port 2 to port 1 then holds and locks the load against movement. The direct-relief function allows flow from port 1 to port 2 when load pressure at port 1 is higher than pressure setting.

  • This is a pilot-operated, poppet type valve.
  • Reduce valve setting and release load by turning screw clockwise.
  • Backpressure at port 2 is added to the relief setting of this valve directly.
  • While a pilot ratio of zero may reduce efficiency, it can enhance overall machine stability.
  • Pressure setting should be at least 1.3 times the maximum load induced pressure. (We suggest when the maximum setting pressure is 280 bar, the load pressure has to lower than 215 bar)
  • This valve is a variation of pilot-assisted counterbalance valves, with the internal pilot assist area is inactive and no connection to port 3.
  • When a valve is set at standard pressure, it is important to note that the reseat percentage should not exceed 85% of the set pressure or it will lower the reaseat performance.
  • Counterbalance valve is ideal for mounting directly near or in cylinder, hydraulic motor and rotary actuator as protection to increase the safety of the circuit.
  • There are two check valve cracking pressures supplied. Winner® recommends to apply the 1.7 bar (25 psi) check except actuator cavitation is a concern.
  • Internal components are made of high-quality alloy steel, processed heat treatment and precision machined to achieve excellent wear resistance, low leakage, smooth movement and long service life.
  • 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.
