H47X, H47H, HH47X, HH47H, H47X, HDH47X butterfly buffer check valves are mainly used at the outlet of water pumps in industrial water supply and sewage treatment plants to prevent medium backflow in the pipeline network. Automatically eliminate destructive water hammer to ensure that the water pump and pipeline are not damaged. The valve mainly consists of a valve body, a valve disc, a buffer device, and a micro regulating valve. This product has the characteristics of novel structure, small volume, low fluid resistance, smooth operation, reliable sealing, wear resistance, and good buffering performance, making it a product for industrial water and urban sewage.
