Type-57LIS Butterfly Valve (3″ – 8″)

Direct Replacement for ISO-5752 Short Pattern Metal Butterfly Valves

Type-57LIS butterfly valves are quarter turn plastic 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-57LIS butterfly valve is well suited for a wide variety of fluid flow applications. The Type-57LIS butterfly valve conforms to ISO 5752 Short Pattern face-to-face dimensions. This allows the Type-57LIS to directly replace metal valves conforming to the same standard. Available as ANSI B16.5 wafer or ANSI B16.5 lug models with 316SS drop-in lug inserts. The Type-57LIS butterfly valves can be pneumatically or electrically actuated.
