What is a counter balance valve?

A counterbalance valve is one of the hydraulic control valves and is used to adjust the flow rate. By installing a counterbalance valve, it is possible to restrict the flow from one direction and allow the flow from the other direction to flow freely. It is used to stabilize the descent speed of machines using hydraulic pressure, and is incorporated in construction machinery and machine tools. Machines that use hydraulic pressure can exert a large force in a small scale, and can be used in a variety of applications by combining them with electric circuits. A counterbalance valve is necessary to control this hydraulic pressure well.
