The counterbalance valve is a hydraulic component that combines the functions of a check valve and a counterbalance valve. The primary function of the valve is to control the direction and speed of fluid flow, thereby ensuring smooth operation of the hydraulic system during load changes. The valve enables fluid to flow freely in both directions while remaining closed by a set pressure, thereby controlling load movement.
The balance valve is a crucial component in the hydraulic system of construction machinery and other mechanical forms that are lowered by gravity. It has a hydraulic circuit that balances the return oil back pressure with the changing load, ensuring reliable stopping at a certain position and control of the balance of the movement when the load drops. This prevents damage to structural and hydraulic parts caused by excessive drops in load.

Balancing valves are widely used in situations where smooth load drop and reciprocating motion stability need to be controlled. For example, in the main girder legs of the high-speed railway bridge erecting machine, the hydraulic lock function of the two-way balance valve is used to support the weight of the bridge erecting machine itself and the weight of the concrete beams. At the same time, when the bridge erecting machine moves up and down, dynamic balance is used to ensure smooth movement. . In the aerial work platform boom, the two-way balance valve prevents the reciprocating movement of the boom from stalling or overspeeding when the luffing angle increases or decreases, thereby avoiding danger.
