Q

The seat of a butterfly valve will most likely be constructed of __________.

🔍 Key Concepts

• Butterfly valve design and operation in low- and medium-pressure piping systems • Difference between valve body/disc materials (metals/alloys) vs. seat materials (sealing surfaces) • Purpose of the valve seat in providing a tight shutoff/seal

💭 Think About

• Think about what part of the butterfly valve the seat is and what it must do when the disc closes against it. • Which type of material is best suited to deform slightly to make a tight seal against a metal disc in a piping system? • Among the listed choices, which ones are hard corrosion‑resistant alloys used for trim, and which option describes a type of material used where flexibility and sealing are needed?

✅ Before You Answer

• Identify that the seat must provide a seal, not structural strength for the whole valve body. • Separate the options into hard metal/alloy vs. deformable sealing material in your mind. • Ask: Which choice describes the general type of material commonly used for gaskets, O‑rings, and soft valve seats, rather than a specific metal alloy name?
