What is the role of the Butterfly Valve in the steam system?

• A. To regulate the flow of steam by opening or closing the valve
• B. To drain condensate
• C. To measure steam pressure
• D. To energize the pump

Answer: (A)

A butterfly valve in a steam system is used to regulate the flow by opening or closing the valve. Its disk rotates to vary how much steam can pass: when the disk is aligned with the pipe, flow is allowed; when turned across the flow, the valve restricts or stops flow. This design provides quick operation and a compact profile, making it ideal for isolating or throttling steam in large lines. It doesn’t drain condensate, measure steam pressure, or energize a pump—those tasks are handled by condensate drains/traps, pressure gauges, and pumps driven by motors, respectively.
