Description :
with zinc nickel alloy 30L 60L 95L hydraulic overcenter valve , VBSO single type counterbalance valve
A counterbalance valve, also known as a load holding valve, is a type of hydraulic valve used in hydraulic systems to control the motion of a load and prevent it from falling uncontrollably due to gravity.
Here is some more detailed information about counterbalance valves:
Function: Counterbalance valves are primarily used to control the descent of a load in a hydraulic system. They provide a back pressure to prevent the load from falling too quickly when the directional control valve is shifted to the neutral position or when the pump is turned off.
Working Principle: Counterbalance valves are typically pilot-operated valves that allow free flow in one direction (usually the extend direction of a cylinder) and control the flow in the opposite direction. They are set to a specific cracking pressure that must be exceeded before the valve will open and allow flow in the opposite direction.
Applications: Counterbalance valves are commonly used in hydraulic systems where there is a need to control the speed of hydraulic actuators, like hydraulic cylinders or motors, to prevent uncontrolled movement and ensure safety.
Benefits: These valves help in maintaining control over heavy loads, preventing equipment damage, and increasing operational safety in various hydraulic applications.
