Manual Plastic Butterfly Valves

Type-57P Lug Butterfly Valves (1-1/2" - 14")

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