We stock two types of air release valves for use with solar collectors. These are very important to ensure that there are no airlocks in the system which would inhibit the pumps from flowing and reducing the overall efficiency of your solar system.
We have the normal 110°C rated air release valve which is suitable for flat plate collectors.
We also stock the 180°C rated air release valve which is suitable for evacuated tube heat pipe collectors.
Both have a 1/2" male fitting and are to be mounted at the highest point in the system.
Please note that stock availability is subject to prior sales. Prices exclude delivery.
