About Online Roma Air Vent

HYDRAULIC FEATURES

The "ROMA" 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. The integrated tap device is equipped with a dual position 90° male seal. Position "A" communicates the system with the upper air discharge recess while position "B" bypasses the system discharge recess and permits its draining through the front slot. This renders it particularly ideal for installation in zones outside buildings where there is a high risk of freezing. The "ROMA" air vent valve 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 input, as in figure "C". When installing it 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.

Efficient Vertical Air Ventilation

Designed for vertical mounting, the Roma Air Vent ensures optimal air release and circulation. Its float-type automatic mechanism helps maintain system efficiency by preventing air blocks without the need for electricity, making it ideal for both residential and commercial environments.


Durable Construction and Simple Maintenance

Constructed from high-quality PVC plastic, this air vent is corrosion-resistant and highly durable. The gasket-sealed structure provides reliable leak prevention, while its non-electric float operation and straightforward design enable easy cleaning and minimal ongoing maintenance.


Quick and Hassle-Free Installation

Featuring a threaded (screwed) connection and standard 1/2 BSP port size, the Roma Air Vent facilitates rapid installation. Its lightweight structure supports effortless mounting, catering to both professional plumbers and DIY users for diverse air ventilation requirements.
