Lifting 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 media backflow and play a role in media checkback. The H42H vertical check valve is open when the media pressure at the inlet is higher than the outlet. Because under the pressure of the inlet medium in the pipeline, the disc in the vertical check valve makes the valve open automatically. When the media pressure at the inlet end is lower than the outlet end, the spring pushes the disc to the seat to close the valve (Note: Springs need to be added under horizontal installation, and springs are not required for vertical pipe installation). The disc will automatically close under the pressure of its own weight and countercurrent media)
