It has the function of compensating for thermal expansion of pipelines. Cold shrink function. Its main features are as follows:<\/p>\n<p>1. Novel and reasonable design, unique structure, light weight, easy to operate, and quick to open and close;<\/p>\n<p>2. In addition to regulating and shutting off, and compensating for thermal expansion and contraction caused by temperature differences in pipelines, telescopic butterfly valves can also facilitate installation, replacement, and difficult-to-repair valves;<\/p>\n<p>3.
