Ball check valve features
- Large flow rate, small flow resistance pressure loss,
- The sealing performance is very good, no noise when closing, which can reduce the water shock wave.
- Can be installed horizontally or vertically.
- It can be used for pump outlets of cold water, hot water, industrial and domestic sewage network to prevent backflow of media.
- All the equipment, devices and pipelinesshould install check valves, In order to prevent backflow of media
