DS341X telescopic butterfly valve
Product number:DS341X
product description:

  The telescopic butterfly valve has the function of automatically compensating for the thermal expansion and contraction of the pipeline to facilitate loading and unloading. It is used to adjust the flow rate of the petroleum, chemical, electric power, papermaking, water supply and drainage, municipal construction and other industrial pipelines with a temperature below 425°C and a nominal pressure below 1.6MPa. And the best device for carrying and breaking fluid.

Features:

1. Unique structure, flexible design, light weight, labor saving, fast opening and closing.
2. The telescopic butterfly valve can not only compensate the function of thermal expansion and contraction caused by the temperature difference and contraction of the pipeline, but also provide convenience for the installation and replacement of maintenance valves.
3. The sealing part can be adjusted and replaced, and the sealing performance is reliable.
