Hydraulic balance valve CBGA threaded cartridge valve CBGA-LAN crane valve

The balance valve is mainly used in the lifting hydraulic system, so that the hydraulic motor and the hydraulic cylinder movement speed is not affected by the load change, keep stable. Its additional check valve function, good sealing, in the pipeline damage or brake failure, can prevent heavy objects free fall caused by accidents.

The balance valve, also called the load holding valve, controls the movement of the load in the following ways:

1, when the pipe or hose is damaged, prevent the sudden fall of the load.
2, prevent the load from slowly falling due to the direction control valve spool oil leakage.
3, when the load is at low pressure or out of control, provide smooth and adjustable movement.
4, when the direction control valve is suddenly closed, provide smooth and adjustable movement.
There are two basic types of action control valves: hydraulic check valves can meet the first two requirements above. The balance valve can meet the above 4 requirements.

The balancing valve has the following functions:

1. Free oil flow in one direction.
2, no leakage load maintenance.
3, resist the pressure impact caused by external pressure or overload load.
4, when the load is too large to cause the cylinder or motor out of control, as no cavitation action control, so that the oil supply speed to reach the pump flow.
5, when the direction control valve is suddenly closed, smoothly adjust the cylinder action.
