Butterfly Valves

Butterfly valves are quarter-turn valves with equal percentage type flow characteristics. They provide moderate flow control and, therefore, can be used for both on/off and modulating service. Good tolerance to suspended solids, but not recommended for use with slurries or debris. The butterfly valve is well suited for a wide variety of fluid flow applications.
