An inner locknut blocks the membrane (Fig.
9) and fixes it solidly to the casing, increasing
safety and functionality. This component
eliminates the risk of losing the membrane in
the case the external cap should unexpected-
ly become loose.
The external cap (Fig. 10) is made of rubber
that is highly resistant to sunlight and saline
corrosion. Its special shape makes it easy to
find the centre, therefore facilitating the
manual regulation of the pressure.
