1/2 inch BSP brass automatic bottle air vent (AAV) / bleed valve with shut off cap that can be used to stop auto venting if so required.

Must be installed in vertical position.

The valve in the picture shows a brass shut off cap, sometimes they have a plastic cap (makes no difference to operation of the valve).

Please note that in certain circumstances air can be drawn into a heating system through an auto valve when the pump is running. If this is the case use the small cap to close off after venting has finished.

** BSP thread sizes are measured a special way - have a look at our information page for more details **
