These ball valves are made primarily of aluminum alloy in a fire engine red finish, that has been heat-treated. The other major components are made of stainless steel and galvanized brass. Some of the major characteriestics of these ball balbes are: the anti-freezing assembly, the position "open" and "close" visualized on these valves, the minimal friction loss by up to three times, the light weight and smaller dimensional design. Complete with a removable carrying handle.
