Hydraulic Pilot Operated Counterbalance Valve with 320 Bar
The balancing valve is a critical component in hydraulic systems, particularly for construction machinery and other equipment that are gravity-lowered. It features a unique hydraulic circuit designed to balance the return oil back pressure with varying loads, ensuring reliable load positioning. This mechanism controls the movement balance when the load is lowered, preventing structural and hydraulic damage caused by rapid drops.
The balance valve plays a crucial role in hydraulic systems, especially in construction machinery and other equipment affected by gravity.
Its hydraulic circuit is meticulously designed to maintain balance by controlling the back pressure of the return oil, ensuring that loads can reliably stop at predetermined positions.

Working Principle
The main function of a bi-directional counterbalance valve is to provide locking in both directions:
Positive direction operation: when the system pressure is higher than the set pressure inside the valve, the hydraulic oil can flow freely, allowing the load to rise or fall.
Reverse direction operation: when the system pressure is lower than the set pressure in the valve, the Pilot Operated Check Valve in the valve closes, preventing the oil from flowing in the reverse direction, thus preventing the load from falling.
