The telescopic butterfly valve has the function of automatically compensating for the thermal expansion and contraction of pipelines for easy loading and unloading. It is the best device for regulating flow and breaking fluid on industrial pipelines such as petroleum, chemical, power, papermaking, water supply and drainage, and municipal construction with temperatures below 425 ℃ and nominal pressures below 1.6 MPa. Features 1. Unique structure, flexible design, light weight, labor-saving, and quick opening and closing. 2. Telescopic butterfly valves not only have the function of compensating for thermal expansion and contraction caused by pipeline temperature difference contraction, but also provide convenience for valve installation and replacement during maintenance. 3. The sealing part can be adjusted and replaced, and the sealing performance is reliable.
