Freeze Protection Valve

The freeze protection valve is designed to preventing from freezing when the air temperature falls, avoiding possible damage to water pipes, solar, etc.


Temperature vs. Course Curve

* based on practical test data


Thermal actuator inside the valve automatically opens when the ambient temperature dropped 3 °C, then causing minimum quantity of relatively warmer water flow toward the drain, reducing the chance of water freezing. Once ambient temperature rises up to 4 °C, the thermal actuator will shut the valve and stop flowing.
