A blue color external paint had been applied on valve body to enhance the corrosion resistance. The seat is available in EPDM material which fit on the disk edge to provide sealing to any leakage. Butterfly valve is made in wafer type design. For wafer type butterfly valve, it is in short body length and flange hole outside of valve body. The valve can choose to have flange holes on the outside of the valve body. The pipe flange is connected by a long bolt that runs through the entire valve body, and the seal between the valve and the pipe flange is realized by the gaskets on both sides of the valve, the flat valve and the O-ring surface. |
