Panoramica
What Is a Flanged Butterfly Valve?
A flanged butterfly valve is a quarter-turn valve designed with integral flange ends on both sides of the valve body. It is directly bolted to matching pipeline flanges, providing a secure connection and stable installation in municipal, waterworks, and industrial piping systems.
Compared with wafer type valves, flanged butterfly valves offer stronger end connection and better alignment support. They are commonly selected for medium and large diameter pipelines where installation stability, pipeline integration, and dependable shut-off are important.
Flanged butterfly valves can be supplied in different body materials, disc materials, seat options, and actuation methods to match pressure class, media conditions, operating environment, and project specifications.
