The MAMMOUTH series butterfly valves utilize a fully elastomer lined body, centered shaft design with either a metal or hard rubber coated disc. The MAMMOUTH is typically used in seawater, fresh water, river water intake and limestone slurry, among other applications. Typical installations include condenser inlet and outlet isolation valves, FGD (Flue Gas De-sulfurization) absorption tower pump isolation, river water intake and tank isolation. The MAMMOUTH valve is manufactured from 42 to 140 inches.
The MAMMOUTH valve is especially designed for large pipe sizes and has all the characteristics of AMRI lined valves.
