Features
The telescopic butterfly valve can be axially extended and retracted within a certain range, and can also overcome the offset caused by the different axes of the pipe docking within a certain angle range, which can greatly facilitate the installation and disassembly of the valve pipeline. The butterfly valve can be used in pipelines of petroleum, chemical, food, medicine, papermaking, hydropower, shipbuilding, water supply and drainage, metallurgy, energy and other systems.
