Butterfly Valve Replacement Stands Up to Corrosion

Asahi/America has expanded its line of butterfly valves to include the Type 57LIS, an industrial quality thermoplastic valve that directly replaces metallic butterfly valves, without modification to the existing piping system, in applications where metal valves constantly corrode. The face-to-face dimensions of the Type 57LIS (the distance between the two existing flanges), are the same as those of the metal valves that the Type 57LIS replaces. It is available in 3-in. to 8-in. sizes in lever style or with Asahi’s Plasgear gear operator, the industry’s first all-plastic housing design. Standard models are supplied as wafer-style for installation between two flanges or factory equipped with 316 stainless steel lugs for end-of-line applications. The Type 57LIS features an ISO 5211 top flange mounting pattern and molded padlock provision for lever handle models. The valve can be electrically or pneumatically actuated using Asahi/America actuators. The Type 57LIS are identical to those of Asahi/America’s Type 57 and Type 57L butterfly valves..
