Cast steel vertical check valve H42H-16C

H42H cast steelVertical Check ValveIt is a valve whose flap slides along the centerline of the valve body. Pipeline vertical check valve is a newly appeared valve, with simple structure, few parts, light weight and other characteristics, plus good workmanship, is thecheck valvesOne of the development directions. However, the fluid resistance coefficient is higher thanSwing Check ValveSlightly larger. Vertical check valves are widely used in petroleum, chemical, pharmaceutical,Power industryVarious kinds of pipelines that need to prevent backflow of media.

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.
