The Freeze Protection Valve is designed to protect water pipe by preventing the water from freezing when the water temperature drops.
When the water temperature falls below 3.8℃, the thermostatic element opens the valve, thereby allowing the water flowing out from the waterpipe and reducing the change of the water freezing in the waterpipe.
Once the water temperature reaches 3.8℃, the Freeze Protection Valve will close again and the water will stop flowing.
