Yikde Hydraulic Lock Check Valve with 320 Bar
Hydraulic lock is a control element in a hydraulic system, mainly used to lock the hydraulic circuit under specific conditions, preventing the flow of fluid to ensure that the actuator (e.g., cylinder) in the system remains in a specific position.
A hydraulic lock usually consists of two hydraulically controlled check valves that can be interlocked 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.
