HYDRAULIC FEATURES

The
"High Flow Capacity" model automatic air vent is an automatic valve
with single float, used for the evacuation and discharge of large
volumes of air from water supply pipes. This sort of air vent may only
be installed vertically. In order to maximize the efficiency of the
discharge, it should be installed at the highest points in the system
or, if this is not possible, a TEE fitting should be installed at the
inlet, as in figure A. When installing at the top of an ascension pipe, a
conveyable discharge hose can be installed (option available only on
request). The particular spherical profile of the internal
floater-obturator in special thermoplastic rubber forestalls water
spatter during the sealing phase, in closure. The absence of sliding
guides, hence drag, allows the spherical floater an elevated velocity
and precision in closing besides avoiding dangerous incrustations. At
the discharge outlet there is a protective catch for dust and lint,
which, over time, could deposit upon the opening of the cap, obstructing
it; moreover, being perforated, anti-tampering seals may be used in
compliance with legislation currently in force.

The
lower anti-spray guard allows the even distribution of hydraulic thrust
across the entire surface of the sphere, limiting the turbulence to a
minimum and guaranteeing a highly precise closure. The "High Flow
Capacity" automatic air vent is used in conditioning plants, sanitary
installations for water distribution destined for human consumption
outside buildings under EN 805, and irrigation plants. The simplicity of
the High Flow Capacity air vent renders maintenance usually
unnecessary. However, in the event of water outflow from the upper seat
of the air vent, substitute the internal sphere-obturator, which is
easily accessible by dismounting the body cap. In case of prolonged
inactivity, .
