Thermostatic Temperature Control Valves

Our Technology

At the heart of each of our valves is a paraffin wax actuator, an “engine” that phase changes from solid to liquid, liquid to solid, in response to temperature variations. This produces a defined and repeatable valve modulation, allowing for precise thermal control based solely on temperature.

We could not use a seal before because we could not allow more than a couple gallons an hour of water to the drain. Your valve dramatically decreases the water usage and as a result reduces the amount we send to drain.
