What type of seat does a butterfly valve have?

• A. Rigid
• B. Resilient
• C. Flat
• D. Conical

Answer: (B)

A butterfly valve typically features a resilient seat design. The resilient seat consists of an elastic material that provides a tight seal when the valve is closed. This design is crucial as it allows for the effective sealing of the valve against the flow of fluid, minimizing leakage and ensuring efficient operation. The resilient seat can accommodate slight misalignments and thermal expansion, making it a practical choice for applications in various industries, including HVAC, water supply, and chemical processing. Its ability to maintain a reliable seal while enduring pressure changes is integral to the functionality of the butterfly valve. Other seat types like rigid, flat, or conical may not provide the same level of flexibility, adaptability, and sealing effectiveness that a resilient seat does, which contributes to its common usage in butterfly valves. Thus, the choice of a resilient seat is both practical and beneficial for maintaining performance and reliability in fluid control systems.
