Yikde Overcenter Valve for Aerial Vehicle AND trailer wrecker
Balancing valves are indispensable in the hydraulic systems of construction machinery and other gravity-lowered mechanical forms. These valves feature a sophisticated hydraulic circuit that meticulously balances the return oil back pressure with the changing load. This ensures the load can be reliably halted at a specific position. Furthermore, they expertly regulate the movement balance when the load is lowered, preventing excessive descent speeds that could potentially harm structural components, hydraulic parts, and pipelines.
Overcenter valves are crucial for controlling the stop and motion of an actuator. Single overcenter valves manage one direction, while dual overcenter valves govern both directions, offering unparalleled precision in hydraulic applications.
Functions:
- Load Lowering Control: This critical function allows the lowering of the load only if there is pilot pressure from the other line. This operation ensures the cylinder's oil supply, effectively preventing cavitation issues.
- Containing Pressure: These valves maintain pressure at the set value and provide pressure relief for peaks caused by shocks or overloads, safeguarding your system.
- Flow Arrest: They halt the flow and the load when the pump is inactive or the directional valve is in a neutral position, ensuring complete control.
- Free Flow for Load Lifting: They enable free flow for load lifting with reduced pressure drops, enhancing efficiency.
These overcenter valves consist of a meticulously engineered body that houses:
- Check Valve: This component allows flow in only one direction, ensuring controlled operation.
- Pilot Piston: It enables the gradual opening of the relief valve, providing smooth and controlled pressure regulation.
- Relief Valve: This valve limits the maximum pressure in the actuator, holds the load securely, and controls its descent during the valve opening by the pilot signal, ensuring safety and precision.
