The function of the lift check valve is to let the fluid flow in one direction to prevent it from flowing backward. The check valve is used in the hydraulic system to prevent oil from flowing in the opposite direction.

The lift check valve is commonly known as the lift check valve, in which the fluid can only flow along the water inlet, but the medium at the water outlet cannot return.

The lift check valve can work automatically. Only when the valve cover is vertically above the valve, the lift check valve will work automatically when the line pressure is in the horizontal position.
