ITV Industrial Tempering Valve

Operation – How the Tempering Valve Works

The tempering water valve (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.

The ITV provides a convenient, economical, and easy-to-use method of tempering hot effluent. Since this drain tempering water valve 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.

Installations

Choosing Your Size

The ITV valves are available with ¾”, and 1′′ NPT water connections. To choose the valve right for your system you will need to calculate your Cv. Refer to our FLOW CALCULATOR for assistance.

Recommended Accessories

For ITV installations, most local plumbing codes will require the installation of a check valve or backflow preventer to isolate the drain line from the potable water. A water hammer arrestor must be installed between the ITV and the check valve/backflow preventer if a check valve or backflow preventer is used. Failure to do so may cause permanent damage to the ITV and void the warranty.

ThermOmegaTech offers an optional water hammer arrestor and backflow preventers to make life easier. Contact us or your local representative for more information on these products.
