What Butterfly Valves suppliers provide

Suppliers in this category cover butterfly valves built around a rotating disc mounted on a shaft, which turns a quarter turn to open or close the flow path. Their compact, lightweight design suits larger pipe diameters where a gate valve would be heavy and costly, and their quarter-turn operation suits both shut-off and throttling duty. The range includes wafer, lug, and flanged body styles, with seat materials selected for the medium and temperature involved. Core competence lies in matching disc and seat materials, actuation method, and pressure class to the application, from water and HVAC systems to chemical and slurry service. Many suppliers also offer manual, pneumatic, or electric actuation and integration support. Compared with gate valves, butterfly valves offer faster operation and lower weight but a partially obstructed bore when open. In the pre-selection phase, compare seat materials and actuation options against your medium and control requirements.

Relevant standards

Butterfly valves are commonly built to EN 593 (metallic butterfly valves) or API 609, with flange connections to EN 1092. Testing follows EN 12266 or API 598, and fire-safe designs may reference API 607.

Frequently asked questions

Can a butterfly valve be used for throttling as well as shut-off?
Yes, butterfly valves are commonly used for both duties, though throttling performance and seat wear depend on the disc and seat design; confirm the manufacturer’s throttling rating before specifying a valve for continuous control duty.
