Lever operated lug butterfly valve
3" - 8", 150 psi | 57LIS series Asahi/America, Inc.

The Type 57LIS butterfly valve is an industrial quality thermoplastic valve that directly replaces metallic butterfly valves, without any 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.
