How It Works

A thermostatic element senses water temperature in the valve. If the temperature falls below 35ºF, the valve will modulate open allowing water to drain from the system. The valve will remain open as long as the water flowing by the sensing element is less than 40ºF. When the water temperature rises above 40ºF, the valve will close.

Installation and Maintenance

Unit should be installed in a vertical orientation with flow direction downward. For full details, see Installation and Maintenance Manual.
