Purpose of Telescopic Soft Seal Flange Butterfly Valve

This butterfly valve is suitable for temperatures ≤ 80 ¡æ and is used in petroleum, chemical, food, pharmaceutical, textile, papermaking, power, water supply and drainage, and gas pipelines. It serves as a flow regulator and shut-off medium, and has the function of compensating for pipeline thermal expansion and contraction.

Characteristics of Telescopic Soft Seal Flange Butterfly Valve

1. Novel and reasonable design, unique structure, light weight, convenient operation, and fast opening and closing.

2. This telescopic butterfly valve can not only regulate flow and intercept flow, but also compensate for the thermal expansion and contraction caused by pipeline temperature difference. It is also easy to install and disassemble, making it a multi-purpose product for one valve.

Installation precautions

1. Before installing this butterfly valve, it is necessary to clean the impurities in the inner chamber.

2. This valve can have a certain range of expansion and contraction. Before installation, the sealing gasket and gland of the expansion and contraction part must be loosened. Then, after the required length of the valve and pipeline, the expansion and contraction sealing gland can be locked.
