                  [Essential information]

                         Retractable butterfly valve is a dual-use products, set telescopic and flange butterfly valve in one. It can be in a certain range of axial expansion, is conducive to the pipeline expansion and contraction, eliminate the offset and the vibration of the pipeline in a certain range to overcome different axial pipe butt and produce, installation and convenient disassembly valve pipeline greatly, thus improving the economic benefit.
