Soft Seal Nodular Cast Iron Carbon Steel Electric Wafer Butterfly Valve DN100

Electric soft seal nodular cast iron butterfly valve is generally a medium structure, mainly composed of soft seal butterfly valve and electric actuator. Electric wafer butterfly valve itself has no flange, the valve body thickness is relatively thin, is directly used a group of screw through the bolt hole, the butterfly feeding clip between the two ends of the pipe flange, and then connected with screw interpretation.
