MasterGuard 680, 2" Thermostatic Mixing Valve, High Capacity (Lead Free)

The MasterGuard 600 Series features a range of high flow rate valves that mix hot water with cold water to deliver water at a safe, controlled temperature, typically 120°F (49°C). It features state of art, fast-acting, high-quality thermostatic mixing valve elements that sense the outlet temperature and react to maintain a stable delivery temperature even under varying and extremely low flows. The adjusting handle can be locked at the desired temperature. 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 can 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”.
