Dual Overcenter Valves: Reliable and efficient control for your hydraulic system.
Balancing valves, essential components in hydraulic systems of construction machinery, are sophisticated devices designed to manage loads lowered by gravity. They feature a hydraulic circuit that balances return oil backpressure with changing loads, ensuring stable load positioning. These valves carefully control movement balance during load descent, preventing excessive speeds that could damage structural and hydraulic parts as well as pipelines.
Our overcenter valves excel in controlling actuator movements. Single overcenter valves manage one direction, while dual overcenter valves govern both directions, offering precise stop and motion control.
Functions:
- Load Lowering Control: Ensures load descent only with pilot pressure from the other line, maintaining cylinder oil supply and preventing cavitation issues.
- Pressure Containment: Maintains pressure at set values and provides pressure relief during shocks or overloads.
- Flow and Load Arrest: Halts flow and load when the pump is inactive or the directional valve is neutral.
- Free Flow for Load Lifting: Facilitates load lifting with minimized pressure drops.
Component Composition:
- Check Valve: Allows flow in a single direction, ensuring unidirectional movement.
- Pilot Piston: Controls the gradual opening of the relief valve for precise adjustments.
- Relief Valve: Limits maximum pressure within the actuator, securely holds the load, and regulates its descent during pilot signal activation.
