Asahi/America, Inc., a thermoplastic valve technology company, has recently expanded its line of valves to include the Type 57IL Isolator Lug butterfly valve. The Type 57IL Isolator Lug features a design whose the 316 stainless steel lugs are inserted into the valve body during the injection molding process, permanently combining the lugs and valve body into one unit. The Type 57IL was designed to allow for removal of the downstream flange while maintaining full upstream line pressure. Encapsulating the 316SS lugs in the PVC valve body ensures that every Type 57IL comes factory-equipped with lugs. Asahi/America has simplified the field installation process by removing the directional requirement of their previous butterfly valve.
