Elite Flow Control’s Butterfly Valves are compact, lightweight, and high-performance quarter-turn valves designed for efficient flow control, regulation, and isolation across a wide range of industrial applications. Manufactured to API 609 and ASTM standards, these valves offer an exceptional combination of reliability, versatility, and cost-effectiveness – making them one of the most widely specified valve types in modern industrial piping systems.
Available in two principal design categories to suit varying service requirements, the range covers everything from standard utility applications through to demanding high-pressure and high-temperature process services. The concentric seat design (Category A) is ideal for general service applications, while the offset seat design (Category B) provides superior sealing performance and extended service life in more demanding conditions – including higher pressure classes and abrasive or corrosive media.
Offered across an extensive range of end connection configurations – including Lug & Wafer, Double Flange Long Pattern, and Double Flange Short Pattern – and available in pressure classes of 150LB, 300LB, and 600LB, these butterfly valves provide outstanding installation flexibility across virtually any plant configuration. With a size range spanning 2″ to 48″ (DN50 to DN1200), Elite Flow Control butterfly valves are equally suited to small-bore utility services and large-diameter pipeline applications.
All valves are constructed from ASTM-standard materials and manufactured in strict accordance with API 609, ASME B16.10, B16.34, B16.5, B16.47, and B16.25 – ensuring full compliance, traceability, and confidence for critical service installations.
