A stainless steel butterfly valve has a bidirectional pressure management mechanism. The valve looks like a butterfly with outer loops for holding the valve tight in place. It takes a 90° turn to open from a closed position fully. Stainless steel butterfly valves are excellent for handling various temperatures and pressures. These valves can be made of aluminum, carbon steel, chromium, nickel, exotic metals, ductile iron, and cast iron. Butterfly valves are widely used in the pharmaceutical, chemical, and food processing industries. Valves are used for controlling hydroelectric power plants and the water flow control in dams.
