Telescopic butterfly valve

Expansion butterfly valve is also a type of flange butterfly valve, which is equipped with an expansion joint on one side of the flange. It can be adjusted to a limited extent according to the length of the left and right pipelines, thus solving the material waste during pipeline connection, especially when one end of the pipeline needs to be adjusted flexibly and the installation is difficult due to space limitations. The main structure of a telescopic butterfly valve includes a valve body, butterfly plate, valve stem, sealing ring, telescopic joint, and transmission device. The valve body is cylindrical in shape, with cylindrical protrusions on the upper and lower parts for installing the two end supports of the valve stem. The butterfly plate is the opening and closing component of the telescopic butterfly valve, usually connected by flange, manually or turbine driven. The telescopic butterfly valves produced by Shanghai Meiyan Yipump Valve are mainly used for water supply and drainage pipelines and ventilation pipelines, and the telescopic length can be customized according to customer needs.
