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.
