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. Pilot operated check valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in reverse direction until pilot pressure is applied. This valve is like a check valve on a single acting cylinder. When pilot pressure is applied, ball moves and provides unloading.

Working principle

 

Its working principle is based on the technology of proportional control valves. It controls the hydraulic pressure to open and close the valve, thereby controlling the liquid to only allow one-way flow, preventing the reverse flow of the liquid from causing system failure or leakage.

 

Specifically, when the VBPSL hydraulic lock valve is under uncontrolled pressure, it behaves as an ordinary one-way valve. The liquid can only flow from the oil inlet to the oil outlet, and cannot flow in the opposite direction; when the hydraulic control port is connected to the control pressure, the valve can be opened to realize the reverse flow or locking function. This design ensures the safety and stability of the hydraulic system, and is especially suitable for occasions that require hydraulic locking and pressure maintenance.
