Concentric Butterfly Valve
concentric butterfly valves are widely used in various industrial fluid control applications.
Product Introduction
concentric butterfly valves are widely used in various industrial fluid control applications. The fully rubber-encapsulated body is suitable for various corrosive service conditions. Compared with conventional gate, globe and ball valves, the weight is much lower. Due to the rapid development of artificial rubbers it is possible to use this valve within the modern chemical industry. butterfly valves with concentric type design comply to API609 standard.
