ED（3/6/9）63H-10/16/25/40C、P、R butt welded hard-sealed butterfly valves
Features
1. ED（3/6/9）63H-10/16/25/40C、P、R butt welded hard-sealed butterfly valve adopts three-eccentric butterfly valve, which known as the leading process valve. The design makes the valve become the ideal bubble-level hard-sealed butterfly valve for the high temperature, high pressure and fire protection applications.
2. Because of the using of welded structure, it makes the valve and pipes reach a permanent zero leakage.
3. There is no flange in butt welded hard-sealed butterfly valve, it is convenient and beautiful for pipes and insulation packing.
