Fixed setting counterbalance valves (overcenter valves) with pilot assist 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-acting, pilot-assisted relief valve section control flow from port 1 to port 2 when pilot pressure is applied. Pilot pressure at port 3 reduces the pressure setting by pilot ratio of counterbalance valve but the pressure required to open the valve and start actuator movement can be calculated as follows: Pilot Pressure = [(Relief setting)-(Load Pressure)]/ Pilot Ratio. Varying the pilot ratios can optimize the hydraulic system by providing stable load control and improving energy efficiency.

  • This is a pilot-operated, poppet type valve.
  • Designing for impact in space-limited applications.
  • Winner offers a variety of seal kit materials for different applications, see seals information under Technical Reference.
  • The pressure setting will increase when back pressure at port 2. PS=(PR+1)xBP; PS=Pressure Setting, PR=Pilot Ratio, BP=Back Pressure
  • 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.
  • The fixed-setting counterbalance valve is not suitable for circuits that require precise valve settings, such as those with dual cylinders. However, it can be applied to prevent damage in some hydraulic systems due to thermal expansion, such as in the cylinder seals of outrigger circuits.
  • 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.
  • 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.
  • Winner guarantees that all products performance a 100% functional test before shipment.
