Butterfly valve features unique lug design

Asahi/America, Inc recently expanded its line of valves to include the Type 57IL Isolator Lug butterfly valve. 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. This distinct design permits removal of the downstream flange while maintaining full upstream line pressure. The field installation process has been simplified by removing the directional requirement of the previous butterfly valve. Each Type 57IL is denoted by a bold “I” where the directional arrow would be on Asahi’s previous butterfly valve versions.
The Type 57IL Isolator Lug retains the proven features of Asahi/America’s Type 57 butterfly valve. The flange stopper with absorption channel technology still makes it virtually impossible to impact the performance of the butterfly valve by over-tightening the mating flanges of the Type 57IL and the molded flange stopper acts as a body-stop, limiting the compression of the valve’s full seat design liner. The valve can also easily be electrically or pneumatically actuated using Asahi/America, Inc actuators.
