Type-57AT Butterfly Valves (1-1/2″ – 14″)

Designed for use with the Asahitec PP-RCT Piping System

Type-57AT 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 Type-57AT butterfly valve is well suited for a wide variety of fluid flow applications.
