China Hydraulic Accessory Cast Steel Counterbalance Valve for Aerial Work Vehicle
The balance valve is mainly used 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 to ensure that the load can reliably stop at a certain position and control the balance of the movement when the load drops, and prevent the damage of the structural parts and hydraulic parts pipeline caused by the excessive drop of the load.
Its main function is to force the check valve to close through the pressure caused by the load when there is no pressure oil in the control port, so as to realize the locking function; and when there is pressure oil in the control port, it realizes the dynamic balancing function through the movement of the main spool to ensure the smooth movement of the actuating element.
