Replace the valve and check the rest of the system and components for blockages air pockets to make sure fluid is actually flowing.

The air temperature is monitored by a sensitive wax filled element which reacts by opening the fpv valve seat when the temperature drops. These frost valves have been successfully used over many years to protect thousands of solar water collectors from occasional mild frosts. When the warmer water reaches the valve the port closes and water discharge stops. The valves have a 3 4 male bsp thread for easy fitting.

Do we really need this anti freeze valve. The hitachi valve will automatically repeat this cycle until the outside air temperatures rise.

The frost protection valve is designed to protect a solar collector panel from frost damage when the outside air temperature drops.
