      • Ordering Process

      H42H, H42W vertical check valves are normally closed, due to the pressure of the inlet end of the pipeline, and overcome the spring resistance to open the valve. When the inlet pressure is lower than the outlet, the spring pushes the spool to the seat and closes the valve, preventing the medium from flowing back, so it has a check effect.


      Since the valve supports the spool with spring, it can be installed vertically or horizontally.
