Understanding Flanged Butterfly Valve Fundamentals

Flanged butterfly valves dominate 38% of global industrial valve applications according to 2023 market data. These quarter-turn rotational motion devices provide superior flow control in pipelines ranging from 2" to 96" diameters. The flanged connection design ensures ANSI Class 150 to 900 pressure compatibility through standardized bolt patterns.

FAQS on flanged butterfly valve

Q: What is a flanged butterfly valve used for?

A: A flanged butterfly valve is primarily used to regulate or isolate fluid flow in piping systems. Its flanged ends allow easy installation between pipe flanges. It is ideal for applications requiring quick shut-off and moderate pressure handling.

Q: How does a double flanged short pattern butterfly valve differ from a standard flanged butterfly valve?

A: A double flanged short pattern butterfly valve has a compact design with flanges on both ends and a reduced face-to-face length. This makes it suitable for space-constrained installations. It retains the functionality of standard valves but optimizes footprint.

Q: What are the advantages of a double flanged triple offset butterfly valve?

A: A double flanged triple offset butterfly valve offers leak-tight performance in high-temperature and high-pressure systems. Its triple offset design minimizes wear and ensures bubble-tight sealing. The flanged ends provide secure connection and alignment in critical applications.

Q: Can flanged butterfly valves handle corrosive fluids?

A: Yes, flanged butterfly valves can handle corrosive fluids if constructed with compatible materials like stainless steel, Hastelloy, or PTFE-lined components. Material selection depends on the specific chemical compatibility and operating conditions.

Q: When should a double flanged short pattern butterfly valve be used over other types?

A: Use a double flanged short pattern butterfly valve in systems with limited space between pipe flanges. It is ideal for low-to-medium pressure water, air, or neutral fluids. Its compact design maintains performance while reducing installation space requirements.
