Wafer Type Butterfly Valve
Technical features and applications
1. It adopts triple offset wafer type and flange structure, with reliable seal performance. When opening the valve, Disc doesn’t touch the seal seat, so it eliminates the un-balanced load of seal seat, so as to prolong the valve’s working life. The valve is also high temperature resistance, wear resistance, and anti corrosion.
2. The valve is widely applied to the pipeline of petroleum, chemical, water treatment, high building, water supply and drainage, etc.
