What to settle before you ask for a quote

General guidance from SourceLoka for butterfly valve; it is not this company’s specification.

  • Size and pressure rating, and the body type: wafer, lug or flanged.
  • Seat type: resilient (rubber or PTFE) or metal, for the fluid and temperature.
  • Body, disc and shaft materials.
  • Operation: lever, gearbox or actuator, and fail-safe position.
  • Leakage class required and the standard the valve is made and tested to.
  • Flange compatibility with your pipe and the certificates supplied.
What is a butterfly valve, and when should you choose another type?

A round disc is mounted on a shaft across the bore of the valve. A quarter turn rotates the disc from lying along the flow, which is open, to across it, which is closed. Bodies are wafer, lug or flanged, and resilient seats give a tight seal on water and many liquids, while high-performance designs with metal seats handle higher temperatures and pressures.

Butterfly Valve or gate valve? A butterfly valve is much lighter, shorter and cheaper in large sizes and opens and closes quickly. A gate valve gives a clear, unobstructed bore when open, whereas the disc of a butterfly valve always sits in the flow.

What is the difference between wafer and lug butterfly valves?

A wafer valve is clamped between two pipe flanges by long bolts and is the lightest and cheapest. A lug valve has threaded lugs, so it can be bolted to one flange and allows one side of the pipe to be removed, which suits end-of-line use.

Can a butterfly valve regulate flow?

Yes, within limits. It is often used for throttling in large lines, but the disc stays in the flow, so check the flow characteristic and the position range with the supplier.
