Keep your solar collectors and exposed pipes from freezing with a SmartTechProducts Solar Freeze Protection Valve. The valve operates without any electrical power. The Solar Freeze protection Valve contains a thermal actuator. When temperatures approaching freezing, approximately 34°F, the valve will open. When properly installed this will allow warmer water supply to slush colder water from your solar panels. When the temperature reaches 39°F the valve will close. This cycle will continue preventing panels and pipes from freezing.

QUESTIONS & ANSWERSAsk a Question
What valve can be used in Climate Zone 6 for this purpose and why can't this one be used there?
Thermostatic valves like SmartThaw™ require warmer ground water temperature to close them. In certain colder zones the ground water is not warm enough to close the valve. If your ground water temperature reaches 40°F or higher in the winter this valve would work. Currently we do not have a valve to work in colder zones.
Hi, What is the max pressure rating? Thanks
Thank you for the question. According to the manufacturer the maximum working pressure for the SmartThaw valve is 145 PSI.
