Asahi/America Type-57 IL plastic butterfly valves are quarter turn valves designed for use in applications where 1-side flange removal may be periodically required. They feature a PVC body with fully molded in 316SS threaded lug inserts for connection to the mating flanges. Type-57 IL butterfly valves permit one side flange removal, while maintaining full line pressure on the opposite side. 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-57 IL butterfly valve is well suited for a wide variety of fluid flow applications. Can be pneumatically or electrically actuated.
IL style (molded) lugged butterfly valves are available in sizes 3" thru 8" (lever), and 3" thru 12" (Gear). Valve sizes 1-1/2 thru 2-1/2 and 14" thru 24" are Non-IL style lugs (machined). Ideal applications for the Type-57 butterfly valve are: Isolation valves, control valves, chemical processing, water treatment, water features, fountains, aquariums, landfills, swimming pools, power plants, mining and transportation.
