Type-56 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-56 butterfly valve is well suited for a wide variety of fluid flow applications. Can be pneumatically or electrically actuated.
Ideal Applications Include: Isolation valves, control valves, chemical processing, water treatment, water features, fountains, aquariums, landfills, swimming pools, power plants, mining, transportation
