Features:
The telescopic butterfly valve is designed for use in water supply and drainage systems, as well as gas pipelines, where it can regulate flow and shut off the medium. It is ideal for applications in food processing, pharmaceuticals, chemical industries, petroleum, power generation, textile, and papermaking. The valve operates efficiently at temperatures below 80°C and with a nominal pressure of less than 1.6 MPa.

This type of valve also offers thermal expansion and contraction compensation, making it suitable for environments where temperature fluctuations are common. Its key features include:

1. A novel and rational design with an optimized configuration, ensuring lightweight construction and easy operation, allowing quick start-up and shutdown.
2. It not only regulates and cuts off the flow but also compensates for temperature differences in the pipeline, enabling expansion when heated and contraction when cooled. This flexibility simplifies installation, replacement, and maintenance.
3. It has replaceable sealing components and reliable sealing performance, ensuring long-term durability and safety.
