Simple but very effective in-line valve for the removal of air bubbles from solar systems. An injector pipe creates a natural chamber for the entrapment of air bubbles circulating around the system. These will gather in the upper part of the chamber until manually vented off.
The valve should always be in a vertical orientation to function. Connections are upper ¾" bsp male and lower 22mm compression. The valve should be position on the flow, with the direction being DOWN, ie from the feed out of the solar collector.
