Cast Steel SO-K8L-J7 Flow Control Valve 320 Bar Hydraulic Lock
The hydraulic lock is a crucial component used in various hydraulic systems, including the outrigger circuit of construction and lifting machinery, self-locking mechanisms in presses, and support wall jacks in mines. Its primary function is to ensure that the working mechanism remains stationary at any desired position and is not affected by external loads.
The hydraulic lock operates by forming a locking system within the hydraulic circuit. It effectively immobilizes the working mechanism by preventing any movement or displacement under external influences. This capability is essential for maintaining stability, safety, and control during operations such as lifting heavy loads or supporting structures.
Overall, the hydraulic lock plays a critical role in hydraulic systems where precise positioning or immobilization of mechanical components is necessary to ensure efficient and safe operation.
