H42Y and H42W lifting vertical check valves are normally in the closed state.Due to the pressure of the medium at the inlet end of the pipeline,the valve is opened against the resistance of the spring.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.
