Rubber Disc Swing Check Valve
The valve adopts full flow area type design, which has the characteristics of small head loss, not easy to accumulate sundries, and simple maintenance. It is mainly suitable for water supply and drainage system, and can be installed at the outlet of water pump to prevent the damage of backflow and water hammer to the pump. It can also be installed on the bypass pipe of the water inlet and outlet pipes of the reservoir to prevent the backflow of the pool water to the water supply system.
1. Light valve body, short opening and closing stroke of disc, streamlined structure, small flow resistance.
2. Short closing time, fast closing function and good energy saving effect.
