Thermostatic Mixing Valves (TMVs)

Commercial, Industrial

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.

Features:

  • Accurate temperature control, even at very low flows
  • Fast reaction to changes in flow rate or supply temperature
  • Robust, low complexity construction for superior reliability and improved user safety
