Press Release Summary:

August 9, 2011 - Available in 3-8 in. lever-style and 10-12 in. gear operator-style, Type 57IL Isolator Lug Butterfly Valve can be electrically or pneumatically actuated. Unit's 316 stainless steel lugs are inserted into PVC valve body during injection molding process, permanently combining lugs and body into one unit. Molded flange stopper acts as body-stop, limiting compression of valve's full seat design liner, while absorption channel acts as stress relief.

Asahi/America Introduces the Type 57IL Isolator Lug Butterfly Valve

Press release date: August 3, 2011

Asahi/America, Inc., the leader in thermoplastic valve technology, has recently expanded their line of valves to include the Type 57IL Isolator Lug butterfly valve. The Type 57IL Isolator Lug features a unique lug design where 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's distinct design permits 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. 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. Because of the flange stopper with absorption channel technology, it is still virtually impossible to impact the performance of the butterfly valve by over-tightening the mating flanges of the Type 57IL. The molded flange stopper acts as a body-stop limiting the compression of the valve's full seat design liner. The absorption channel acts as stress relief by allowing for a molded body area for the valve liner to migrate to in the event of over-compression. The valve's spherical disc design provides high cycle life expectancy, while also improving flow characteristics across the valve resulting in higher CV values than previously achievable.

Asahi/America's Type 57IL Isolator Lug butterfly valves are available in 3" to 8" as lever-style (with an option for a gear-operator) and 10" to 12" as gear-operator-style only. The Type 57IL features a non-wetted, low profile valve stem, ISO 5211 top flange mounting pattern, full seat liner design, and a molded padlock provision for lever handle models. The Type 57IL can also easily be electrically or pneumatically actuated using Asahi/America, Inc. actuators.
