Mixing valves are devices that blend multiple streams of fluid at varying temperatures to produce a desired output temperature. Hot and cold water mixing valves maintain a safe and consistent water temperature for washing and showering. Steam and cold water mixing valves are used in commercial and industrial applications to mix steam and cold water until it reaches a desired temperature. Emergency fixture mixing valves blend hot and cold water to create a desired temperature for immediate use in eye and face wash stations or drench showers. Mixing valve repair kits and replacement parts include parts and components used to maintain valves or replace old or worn parts.
