7.3.3 Exhaust valve
The exhaust valve is constantly subjected to the rapid exhaust of all the compressed air inside the
pressure pot along with any blast media which may be carried through by the stream of air.
Consequently the interior of the valve, particularly the diaphragm, is potentially subject to a high rate
of wear. This wear will increase if the pressure pot is regularly exhausted when full of media as
opposed to when all the media has been expelled. Regular inspection is necessary to prevent
premature failure of either the valve or of the diaphragm.
