Automatic air vent valve with shut-off valve ALFA white 1/2 inch 4700230

Automatic air vent – reliable air removal from the installation

This automatic air vent with an isolating valve from VALVEX, in white color and with a diameter of 1/2 inch, is a key element of every heating installation. Its task is to effectively remove air, which translates to optimal system performance and prevents problems such as water stagnation or corrosion. The additional isolating valve facilitates servicing and allows for safe disconnection of the air vent without the need to drain the entire installation.

Construction and materials – durability and resistance

The valve is made of dezincification-resistant brass (DZR), which guarantees its strength and corrosion resistance, even in harsh operating conditions. The body, nut and isolating valve body are coated with a primer paint, providing additional protection against external factors. Internal elements, such as the nozzle, float and plate, are made of POM (polyoxymethylene), and the flat spring of steel – this combination of materials ensures reliable operation for a long time. An EPDM rubber seal further increases the tightness and durability of the device.

Application and benefits – for installers and users

The ALFA valve is perfect for heating installations using water or glycol solutions as a heating medium. Its installation is quick and easy, which will be appreciated by professional installers. Automatic venting eliminates the need to manually vent radiators, saving time and ensuring user comfort. Thanks to this, the system operates quietly and efficiently, and users can enjoy optimal thermal comfort. The isolating valve allows for easy removal for cleaning or replacement without having to shut down the entire system.
