Pilot check valves are used to block the cylinder in both directions. Flow is free in one direction and blocked in the reverse direction until pilot pressure is applied.

VBPDE-A先导式液压锁用于在进油、回油两个方向上锁住油缸。当先导油液没有施加在对侧方向的回路时，油液正向自由流动，反向截至，即为单向阀功能。当先导油液施加在对侧回路时，则正向、反向均可流动。

DOUBLE PILOT OPERATED CHECK VALVE

VBPDE 1/2 A | V0190

A check valve is the simplest type of directional control valve used in hydraulic systems. Check valves stop the flow of fluid in one direction and allow free flow in the opposite direction. They are also known as non-return valves.

These valves are used to block the cylinder in both directions. Flow is free in one direction and blocked in the reverse direction until pilot pressure is applied.

They are used on double acting cylinders. Location of the ports on this model are different than standard version (VBPDE).
