H42H cast steel vertical check valve is a valve whose flap slides along the centerline of the valve body. Pipeline vertical check valve is a new kind of valve, has a simple structure, few parts, light weight and other characteristics, plus good workmanship, is one of the development direction of the check valve. But the fluid resistance coefficient is slightly larger than the swing check valve. Vertical check valves are widely used in petroleum, chemical, pharmaceutical, electric power industry and other various need to prevent the backflow of media on the pipeline.
Working Principle
H42H series vertical check valve can prevent the media backflow, play the role of media check.H42H cast steel vertical check valve at the inlet end of the media pressure is higher than the outlet end in the open state. Because of the pressure of the medium in the pipeline at the inlet end, the top of the vertical check valve in the valve flap, so that the valve automatically open. When the pressure of the medium at the inlet end is lower than the outlet end, the spring pushes the valve flap to the valve seat and closes the valve.
