The DTV can be used in applications where a high temperature discharge flow to a drain or sewer must be tempered with cold water. 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 about 10°F below the full open temperature, the cold-water inlet is fully closed to conserve water.
The DTV provides a convenient, economical, and easy to use method of tempering hot effluent flows. Since the DTV is open only when the effluent exceeds the specified set point temperature, it also conserves water by automatically turning off cold water when not needed.
