Working principle and purpose of the product:

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 used as a device for regulating flow and breaking fluid in industrial pipelines such as petroleum, chemical, power, papermaking, water supply and drainage, and municipal construction, with a temperature below 425 ℃ and a nominal pressure below 1.6MPa.

Product Structure Features:

1. Unique structure, flexible design, light weight, effortless operation, and quick opening and closing.

2. The telescopic butterfly valve not only compensates for the thermal expansion and contraction caused by temperature difference in the pipeline, but also provides convenience for the installation and replacement of maintenance valves.

3. The sealing part can be adjusted and replaced, with reliable sealing performance, low flow resistance, and energy saving.
