Ductile Iron Cast Steel Hydraulic Butterfly Type Buffered Check Valve
Product introduction:
H47X series butterfly type buffer check valves including model number as H47X, H47H, HH47X, HH47H, H47XF, and HDH47X, which is 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 pipelines are not damaged. The valve is mainly composed 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. It is the best product for industrial water use and urban sewage discharge.

Product features:
1. This valve is mainly used on water pipelines with working temperatures below 80℃, to prevent media backflow, protect pipelines, water pumps or fans from damage.
2. Advanced design and valve disc automatically opens and closes under the action of the medium. In order to prevent the valve disc from quickly closing and causing vibration in the pipeline, an oil pressure buffer device is designed at one end of the valve stem. But in order to ensure reliable sealing of the valve under low back pressure, a closing aid device was specially designed on the valve.
