SmartThaw™ Freeze Protection Valve

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 are approaching freezing, approximately 34°F, the valve will open. When properly installed, this will allow warmer water supply to flush 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. 3/4" x 3/4" Male Pipe Thread  Use in zones 1-4.
