YiKDE Check Valve Hydraulic Control Valve Hydraulic Lock with Cast Steel
The function of the hydraulic lock is not only to maintain pressure and prevent the hydraulic cylinder piston ram and other moving parts from slipping but also to realize the locking of the hydraulic cylinder to ensure that the piston will not be moved by external forces when the reverse valve is in the neutral position.
In addition, the hydraulic lock can also be used for high-flow oil discharge, as a charging valve, or as a combination of directional valves.
In general, a hydraulic lock is an important hydraulic system component that through reasonable design and selection, can ensure that the hydraulic system is stable and safe to operate.
