The vertical check valves H42H and H42W are normally in the closed state. Due to the pressure of the medium at the inlet end of the pipeline, the valves overcome the spring resistance and open. 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.
This valve can be installed vertically or horizontally due to the use of a spring supported valve core.
