LHDV - Over-center valves

Over-center valves, also known as load-holding valves or counterbalance valves, are critical components in the hydraulic industry. These valves are designed to control the movement and position of hydraulic actuators, such as cylinders and motors, ensuring smooth and stable operation, especially in load-holding applications
Function and Operation
1. Load Control: Over-center valves are primarily used to control and maintain the position of a load in hydraulic systems. They prevent runaway loads and ensure precise control over the movement of the actuator.
2. Safety: These valves enhance the safety of hydraulic systems by preventing uncontrolled descent or movement of the load in the event of a hose or line failure. They act as a brake, holding the load securely in place until hydraulic pressure is intentionally applied to move it.
3. Pressure Relief: Over-center valves often incorporate a built-in pressure relief function. This prevents excessive pressure build-up, which can cause damage to the hydraulic components or the load being controlled.
Over-center valves are essential components in the hydraulic industry, providing crucial control and safety functions in various applications. Their ability to hold loads securely, control movement precisely, and enhance the overall safety and reliability of hydraulic systems makes them indispensable in modern hydraulic applications.
