Fully Balanced load control valves have checked and fixed throttle characteristic. When load pressure at port 2 rises over the check cracking pressure, the check valve allows free flow from port 2 to port 1. Meantime, the pilot activates the 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.

  • This valve has no relief function, including thermal expansion relief.
  • The valve automatically compensates for load pressures, ensuring self-balancing. Flow is controlled via pilot pressure, with port 1 designated for the load and port 2 for the tank, thanks to the presence of dynamic seals that optimize performance.
  • Pilot pressure at port 3 against with back pressure at port 2.
  • While this valve can be used to replace a counterbalance valve, it may not be suitable for cross-piloted cylinder applications. For optimal machine stability, a low pilot ratio is required, and a balanced load control typically has an extremely high pilot ratio.
  • If individual pilot resource is applied, it could smoothly apply pressure to control loading stability.
  • 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 fully balance 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.
  • Configuration Y=0050, 0105, 0140 are not design for leak free application.
  • Maximum valve leakage at reseat Y= 0200, 0330, 0367 ranges: no more than 0.4 cc/min. at below cracking pressure; 0050, 0105, 0140 ranges: no more than 50 cc/min. at below cracking pressure.
  • 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.
