TAV 50 Automatic High Vacuum Valves

The use of automatic valves in a high vacuum extraction system provides significant energy savings. By installing an automatic valve at each extraction point or connected tool, extraction is activated only when the tool is in operation or when a specific process is being carried out. The valve automatically closes when the operation is completed.

This approach allows the extraction system to be sized and operated according to the simultaneity factor, resulting in lower energy consumption and improved overall system efficiency.

The TAV 50 range consists of valves designed for the automatic opening and closing of extraction points connected to a centralised high vacuum system. The range includes six different models, each developed for specific applications.

TAV 50 valves open and close by means of a control device, which may be either a solenoid valve for electrical control or a flow sensor that detects airflow to a pneumatic tool. All versions are pneumatically actuated using compressed air, except for the TAV MA, which is manually operated.

All TAV 50 models are CE marked. Depending on the model and application, certain versions are also marked with the Ex symbol and category designation. All TAV 50 valves bearing the Ex marking are classified as Category 3D equipment in accordance with Directive 2014/34/EU (ATEX). This means that Ex-rated models may be installed in areas classified as Zone 22 in accordance with Directive 1999/92/EC.

The TAV 50 MA manual valve is not marked with the Ex symbol, as manually operated equipment does not fall within the scope of Directive 2014/34/EU (ATEX).

Although the TAV 50 MA is not Ex marked, it is particularly suitable for use in Zone 22 classified areas and provides the same high level of protection as the Ex-certified TAV 50 models.

Please note that the TAV 50 MV-W and TAV 50 MV 24 V AC/DC versions are not marked with the Ex symbol and must not be installed in classified hazardous areas.

The TAV 50 is designed for use as part of an extraction ductwork system.

Although the Ex-marked TAV 50 is classified as Category 3D equipment for use in Zone 22 (external environment of the TAV 50), it may also be used in ducting systems internally classified as Zone 20 or Zone 21.

As there is no ignition source inside the TAV 50, it is considered to be part of the ductwork itself and therefore falls outside the scope of Directive 2014/34/EU (ATEX) for the internal classification of the extraction system.
