Product Description

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, the device should be disinfected according to EN 805 12. This product adheres to the standards set forth by the international health authorities for the transport of alimentary fluids and potable water.
