The Type 57IL Isolator Lug butterfly valve features a distinct lug design. During the injection molding process used to make the polyvinyl chloride (PVC) valve body, Type 316 stainless steel lugs are inserted into the body, thereby permanently combining the lugs and body into a single unit. This permits removal of the downstream flange while maintaining full upstream line pressure. Encapsulating the lugs into the body also ensures that every valve comes factory-equipped with the lugs. The valves are available in 3–8-in. lever-style configurations (with the option for a gear operator), and 10–12-in. gear-operator configurations. They can also be electrically or pneumatically actuated.
