Pneumatic Telescopic Butterfly Valve Product Overview

The SD643H pneumatic telescopic butterfly valve is suitable for applications in food, pharmaceuticals, chemicals, petroleum, power, light textiles, papermaking, and other industries, where it is used in water supply and drainage systems and gas pipelines with temperatures ≤90°C and nominal pressure ≤1.6MPa. It serves to regulate flow and shut off media, while also compensating for the thermal expansion and contraction of pipelines. The main features of the pneumatic telescopic butterfly valve are as follows: innovative and rational design, simple structure, lightweight, easy operation, and quick opening and closing. In addition to its functions of regulating and shutting off flow, as well as compensating for thermal expansion and contraction caused by temperature differences in pipelines, the pneumatic telescopic butterfly valve also facilitates the installation, replacement, and maintenance of the valve. The sealing components can be adjusted and replaced, ensuring tight
