This company’s Type 57IL Isolator Lug butterfly valve features a unique design in which the 316 stainless-steel lugs are inserted into the valve body during the injection-molding process. Doing so permanently combines the lugs and valve body into one unit. The 57IL allows removal of the downstream flange while maintaining full upstream line pressure. The valve’s spherical-disc design provides high cycle life expectancy. The 57IL is available in sizes from 3 to 8 in. as a lever style, and in 10- and 12-in. sizes as a gear-operator style. It can be electrically or pneumatically operated. — Asahi America Inc., Malden, Mass.
