Features:

1.This series of valves adopts a modular design: by adding a telescopic joint to the butterfly valve, the butterfly valve can have the compensation ability of the telescopic limit joint, saving the installation distance and effectively reducing the cost of the project.

2.Telescopic joint can be used for different type of butterfly valve.

3.Application: water conservancy, municipal administration, and construction buildings, etc.
