The MasterGuard Series is a High Flow Temperature Actuated Mixing Valve that mixes hot water with cold to deliver tempered water at a controlled temperature up to 150°F (66°C) maximum.

The MasterGuards are central mixers intended for installation in the plant room of commercial and industrial facilities to distribute controlled temperature water to the domestic hot water system of a whole building or a section of the building. The MasterGuard incorporates a fast acting, high quality thermostatic element that senses the outlet water temperature and reacts to maintain a stable delivery temperature even under changing flows or variations in supply temperatures. The valve also greatly reduces the outlet flow in the event of a cold water supply failure.

The MasterGuard features a robust design based on the expertise gained from years of experience in the design and manufacture of safety valves. Every valve is tested for performance on an automated testing station during the assembly process. The valves are third party listed to ASSE 1017 and CSA B 125.3 standards. The MasterGuard valves have an adjusting knob that can be locked at a desired temperature. Alternatively it can function in an adjusting mode, with the handle clearly marked to indicate the direction to turn to achieve hotter or colder water temperatures.

The MasterGuard is shipped complete as a kit with service fittings (integral shut-off valve and gauge port) on each inlet. The check valve and strainer assembly are housed in the body of the valve for easy serviceability. The valves comes with a temperature gauge that could be mounted either on the mixed outlet or the two inlets. The service fittings have a female inlet thread that secure to the base through union connections. The mix water outlet is female NPT. The MasterGuard series is available in sizes from ¾" to 2".
