Electric Actuated Telescopic Butterfly Valve

The electric telescopic butterfly valve primarily consists of an electric actuator and a flanged telescopic butterfly valve. The telescopic butterfly valve incorporates an expansion joint matching the valve's nominal diameter onto the standard butterfly valve body. This structural design not only facilitates valve disassembly but also alleviates pipeline stress. It simultaneously resolves internal forces generated by temperature differentials, compensating for thermal expansion and contraction caused by thermal variations in the pipeline.
