The Emergency Tempering System incorporates 2 emergency mixing valves capable of controlling outlet temperature over a wide range of flows and employ a liquid-filled thermostatic motor and a stainless steel sliding piston control device. The valves offer positive hot water shut-off in the event of cold water supply loss and full flow cold-water bypass in the event of hot water supply loss or thermostatic failure. The system also incorporates a device capable of flattening temperature spike through the system as well as a heat trap to prevent heat migration to the cold side of the mixing valves.
