Overview: 

 The electric telescopic butterfly valve is a multi-functional control valve that integrates the electric drive unit and the telescopic compensation structure on the basis of the ordinary butterfly valve. The core function is to drive the butterfly plate to rotate by the electric device to realize the on-off/flow adjustment of the medium. At the same time, it uses the telescopic joint to compensate for the displacement caused by thermal expansion and cold contraction and installation deviation of the pipeline to avoid the pipe The stress is transmitted to the valve or equipment to ensure the stable operation of the system. It has the dual characteristics of "flow control" and "displacement compensation". It is widely used in large-caliber, medium and low-pressure pipeline systems in water supply and drainage, HVAC, metallurgy, electricity and other industries, especially suitable for scenarios with large pipe temperature difference, high installation accuracy requirements or vibration. 

 Characteristics: 

 1. Novel design, reasonable, unique structure, light weight, easy operation, quick opening and closing; 

 2. In addition to adjusting and intercepting the flow and compensating for the heat expansion and cold contraction caused by the temperature difference of the pipeline, the telescopic butterfly valve can also provide convenience for the installation, replacement and maintenance of the valve. 

 3. The sealing parts can be adjusted and replaced, and the sealing performance is reliable.

Each process, each facility, and each environmental constraint has its own special requirements. Therefore, Dongyan offers a comprehensive range of products covering different performance levels, pressures, different functions and different materials.
