Butterfly valves are quarter-turn valves valued for compact, lightweight construction and economy at large diameters. Selection considers disc/liner material compatibility, seating type (concentric, double-offset, triple-offset), pressure class, and face-to-face standard. They suit moderate-pressure on/off and some throttling duties.
Q: What is a butterfly valve used for?
A: Butterfly valves are used for on/off isolation and moderate throttling, especially in large-diameter water, HVAC, and process lines where weight and cost matter.
Q: Which standards govern butterfly valves?
A: Common references include API 609, ISO 5752, MSS SP-67, and AWWA C504 for water service.
Guidance reflects general engineering practice for butterfly valves; confirm against the project specification and applicable standards before procurement.
