As the pressurised water enters the
VV chamber it pushes up on the
diaphram closing the water valve.
During normal operation the
vacuum valve will cycle between
the open and closed state.
Compressed air exits the nozzles
creating a vacuum on the water
side. The negative pressure pulls
the VV diaphragm down, opening
the water valve.
