A counterbalance valve, also known as a load-holding valve or backpressure valve, is a type of hydraulic valve used to control the movement and stability of a load in a hydraulic system. It is specifically designed to hold a load in position and prevent it from free-falling or drifting due to gravitational forces or external loads.
The primary function of a counterbalance valve is to provide a backpressure that opposes the force of gravity or external loads acting on a hydraulic actuator, such as a cylinder. It achieves this by regulating the flow of hydraulic fluid and maintaining a specific pressure on the actuator's outlet side.
