Function:

1. Maintaining the balance of the crane
Counterbalance valve can control the flow of hydraulic oil to ensure that the crane is balanced during the lifting process, preventing the boom or lifting arm from tilting or even losing balance due to uneven distribution of hydraulic energy.
2. Control of hydraulic cylinder speed
Balance valve can regulate the flow and flow rate of hydraulic oil, so as to control the movement speed of the hydraulic cylinder, make the boom, arm and lifting device and other working parts run stably, improve the working efficiency and safety of the crane.
3. Preventing hydraulic cylinders from malfunctioning
Counterbalance valve can prevent the hydraulic cylinders from operating incorrectly when they are subjected to external force in a specific direction. By generating back pressure in the direction of the force on the cylinder, it prevents movement in that direction, thus preventing the hydraulic cylinder from malfunctioning due to external force.
4. Improved energy efficiency
Balance valve can optimise the energy distribution in the hydraulic system, reduce energy loss, improve the energy efficiency of the crane hydraulic system.
5. Precise control of crane movements
In the crane lifting, lowering, telescoping, rotating and other operations, the balance valve can accurately adjust the hydraulic flow and pressure according to the operational requirements, to ensure that the crane works stably according to the instructions.
6. Preventing the piston of the hydraulic cylinder from slipping
In the winch system of the crane, the counterbalance valve can prevent the piston of the hydraulic cylinder from slipping under the action of heavy loads to ensure the safety of the crane when working at height.
