Control Valve VBPDE-G38 Hydraulic Lock for Mini Excavator
A hydraulic lock is a control element in a hydraulic system that is mainly used to lock the hydraulic circuit under specific conditions, preventing the flow of fluid to ensure that the actuators (e.g. cylinders) in the system remain in a specific position.
Hydraulic lock is an important safety component in the hydraulic system, the correct selection and use of hydraulic locks to ensure the safe, stable and reliable operation of the system is critical.

A hydraulic lock usually consists of two hydraulically controlled check valves that interlock to allow the cylinder to remain stationary in the absence of an external control signal.
When the system pressure is higher than the set value, the hydraulic lock opens, allowing the oil to flow and the actuator to move.
When the system pressure is lower than the set value or there is no control signal, the hydraulic lock closes, preventing the flow of oil and keeping the actuator stationary.
