METTLE VALVES MFG. CO. is known as one of the leading manufacturers and suppliers of different types of Butterfly Valves and many other valves products.

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing or partially obstructing various passage ways. Valves are technically fitting, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The main parts of the most usual type of valves are the body, bonnet, ports, handles, actuators, disc, stem, seat, gasket, spring and trim.
