Introduction
A unidirectional balance valve, also known as a support valve or counterbalancing valve, is a composite valve that integrates the functions of a check valve and an adjustable relief valve. Its main purpose is to control the uniform and stable lowering or retraction of an actuator (such as a hydraulic cylinder or hydraulic motor) under the influence of gravity, preventing it from stalling, losing control ("nodding," shaking, or free-falling).
Simply put, it allows hydraulic fluid to flow freely in one direction (check valve function) and to flow in a controlled, restricted manner in the opposite direction (relief valve function).
Working Principle
Counterbalance valves work on the same principle as internal leakage one-way sequence valves, according to the different forms of control, counterbalance valves also have internal and external control points.
