Vertical upgrade check valve

Product structure 

 Nominal diameter: DN15-DN200 

 Product Model: H42H, H42Y 

 Pressure range: 1.6-4.0MPa 

 Product use 

 H42H and H42Y carbon steel vertical check valves can prevent the backflow of the medium and play the role of stopping the medium. The H42H 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 disc in the vertical check valve is opened so that the valve can be opened automatically. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve disc to the seat to close the valve (Note: a spring is required for horizontal installation, and a spring is not required for vertical pipe installation. The disc will automatically close under its own weight and the pressure of the countercurrent medium)
