Overview of Stainless steel vertical check valve:
H42W stainless steel flanged vertical check valve is a valve whose disc slides along the center line of the valve body. Pipeline vertical check valve is a new type of valve. It has the characteristics of simple structure, few parts, light weight, and good manufacturability. It is one of the development direc
tions of check valves. However, the fluid resistance coefficient is slightly larger than that of the swing check valve. Vertical check valves are widely used in various pipelines that need to prevent the medium from flowing back in the petroleum, chemical, pharmaceutical, and power industries. H42H can be equipped with spring or no spring according to vertical installation or horizontal installation.
Stainless steel vertical check valve H42W flange vertical check valve working principle:
H42W series vertical check valve can prevent the medium from flowing back and play the role of medium check. H42W stainless steel vertical check valve is open when the medium pressure at the inlet end is higher than the outlet end. Because under the pressure of the medium at the inlet end of the pipeline, the valve clack in the vertical check valve is pushed up to automatically open the valve. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the disc toward the valve seat to close the valve. Under the pressure, it will automatically close.
