Gases

A butterfly valve is a rotary valve (quarter turn valve) using a disc as the closure member. Concentric butterfly valve is available with wafer style, lugged and double-flanged body types. This along with comparably short face-to-face dimension makes them versatile and cost-efficient solutions for a variety of on/off and control applications.
