Let's talk about pneumatic butterfly valve first. The relationship between the opening of the pneumatic butterfly valve and the flow is basically linear proportional. If it is used to control the flow, its flow characteristics are also closely related to the flow resistance of the piping. If the diameter and form of the installed valves of the two pipelines are identical, but the pipeline loss coefficient is different, the flow of the valves will also be greatly different.

Function of pipeline compensator:
1. Compensate the axial, transverse and angular thermal deformation of absorption pipe.
2. The elasticity of the corrugated compensator is convenient for the equipment and disassembly of the valve pipeline.
3. Absorb equipment oscillation and reduce the impact of equipment oscillation on pipeline.
4. Absorb the deformation of pipeline caused by earthquake and ground subsidence.
