A Butterfly Valve is a versatile ball valve–style quarter-turn flow control device designed for compact installation and efficient operation. The valve body is commonly manufactured from stainless steel or other durable materials, providing strength and reliability in a wide range of industrial systems. When fully open, the disc allows smooth flow with minimal pressure drop. Butterfly valves are available in multiple connection and performance configurations, including Wafer Type, Lug Type, and Flanged designs, as well as Double Eccentric and High-Performance constructions for demanding applications. For corrosive services, Fluoropolymer Lined butterfly valves using PTFE, PFA, or FEP linings offer excellent chemical resistance and long-term sealing performance across diverse process industries.
