FP Series Thermostatic Antifreeze Valve
Industries: Heating, Refrigeration
The Robertshaw® FP-45 Antifreeze Valve uses a reliable, self-contained power element that is sensitive to temperature and operates without electrical power or sensors. In solar applications, the gate of the valve typically opens as temperatures decrease, allowing the liquid to spill and to be replaced by warmer water when the water is near the freezing point in solar panels. When warmer water enters, the gate of the valve is closed and the removal of water is interrupted.
