Stay Out of Hot Water with DTV MAG’s Drain Tempering Valve Keeps Drain Water Up to Code!
The DTV is installed into the drain line such that the hot effluent passes over the thermal actuator of the DTV and this thermal actuator controls the cold water inlet port. If the hot effluent is above the specified set-point, the DTV opens to allow injection of cold water. As the hot effluent cools, the DTV automatically modulates to reduce the cold water inlet flow. At -12°C below the full open temperature, the cold water inlet is fully closed to conserve water. Since the DTV is open only when the effluent exceeds the specifed set-point temperature, it conserves water by automatically turning off cold water when not needed.
