Wastewater Tempering Valve Overview
The ITV is designed for industrial systems that discharge high-temperature effluent to a drain or sewer. Installed in the discharge line, it helps maintain drain temperatures within applicable plumbing code limits and protect downstream PVC piping from over-temperature conditions.
Its compact design and standard pipe-fitting installation make the ITV easy to integrate into industrial equipment and facility piping, including confined spaces such as tight mechanical rooms. The valve can operate in any orientation and adapt to a wide range of drain sizes and piping arrangements.
Design Features
- Exclusive Thermoloid® paraffin wax actuator
- Corrosion-resistant – stainless steel construction
- ¾” and 1″ NPT connections
- Rugged, clog-resistant valve design
- Effluent tempering capacity limited only by cold water flow rate through ITV
Industrial Applications
- Autoclave drain
- Boiler blowdown line
- Humidifier discharge drain
Markets Served
- Breweries
- Food processing facilities
- Municipal sewage systems
- Pharmaceutical facilities
Recommended Accessories
For ITV installations, most local plumbing codes will require a check valve or backflow preventer to isolate the drain line from the potable water supply. When either device is used, a water hammer arrestor must be installed between the ITV and the check valve/backflow preventer. Failure to install the required water hammer arrestor may cause permanent damage to the ITV and void the warranty.
The ITV is available as a complete kit with a tee, water hammer arrestor, and backflow preventer to simplify component selection for new installations.

How the Industrial Tempering Valve Works
The ITV Industrial Tempering Valve is installed into the drain line such that the hot effluent passes over the thermal actuator, which controls the cold-water inlet port. If the hot effluent is above the specified set point of the valve, the actuator senses the rising temperature and signals the ITV to open to allow the injection of cold water to temper down the discharge fluid before it reaches the drain.
As the hot effluent cools, the ITV 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 again to conserve water.
