The ultimate solution for precise flow control with our top-of-the-line overcentre valves. These high-performance valves are designed to provide exceptional stability, safety, and efficiency for a wide range of hydraulic systems. Our overcentre valves are engineered with precision and built to last, ensuring reliable performance in even the most challenging environments. Whether you need a valve for controlling the descent of a hydraulic cylinder or preventing load runaway, our overcentre valves deliver superior performance and precision. Overcentre valves give static and dynamic control of loads by regulating flow into and out of hydraulic actuators. The Overcentre valve will stop the load from running away in the event of a hose burst. If open center directional control valves are used, they will allow the thermal expansion relief of the hydraulic fluid. These valves provide excellent hose burst protection. Available in a range of sizes and configurations to meet the unique needs of your hydraulic system, whether you need a compact, space-saving valve or a heavy-duty valve for demanding applications, we have the perfect solution for you.

The check section allows free flow into the actuator (from 2 to 1) then holds and locks the load against movement (from 1 to 2). The pilot pressure in the pilot port (3) will give a controlled movement to piston when the pressure is applied. The pressure required to open the valve and allow movement depends on the pilot ratio of the valve.

Crafted from premium materials, our valves are designed to withstand extreme pressures and temperatures, making them suitable for use in a wide range of industries, including construction, agriculture, and mining. With their user-friendly design and straightforward operation, our overcentre valves offer unparalleled control and safety, ensuring optimal performance and longevity. Pilot Ratio 4:1 – Best suited for applications where the load varies and machine structure can induce instability. Other ratios can be made available upon request.
