Structural features

H42W stainless steel flange vertical check valve is normally closed. Due to the pressure of the medium at the inlet end of the pipeline, the valve is opened by overcoming the resistance of the spring. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the valve core toward the valve seat to close the valve, preventing the medium from flowing back, so it acts as a check. Since the spring is used to support the valve core, vertical or horizontal can.
