1H42Vertical check valve Overview
H42The vertical check valve is normally in the closed state, and due to the pressure of the medium at the inlet end of the pipeline, it overcomes the spring resistance to open the valve. When the pressure of the medium at the inlet end is lower than that at the outlet end, the spring pushes the valve core towards the valve seat, causing the valve to close and preventing the medium from flowing back, thus playing a check function.
H42Vertical check valves can be installed vertically or horizontally due to the use of spring supported valve cores.
