This drain tempering valve (DTV) from Therm-Omega-Tech is designed for applications where discharge flow to a drain or sewer must be tempered. Hot effluent passes over the thermal actuator, which opens the cold water inlet port only when the effluent exceeds a specific setpoint temperature. 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. This self-operating, clog-resistant valve requires no outside power source and is easy to install with standard pipe fittings and tools.
