FAQs
Frequently asked questions about pneumatically operated valves, applications and customised solutions from AIRTEC.
This depends on the actuation type. Valves with mechanical spring return typically require a pilot pressure of 2 to 3 bar to overcome the spring force. Bistable valves only require this pressure briefly for the switching operation itself, after which they maintain their position without a continuous signal. For air spring return models, the pilot pressure depends on the operating pressure; exact limits can be found in the performance diagrams of the respective datasheet.
Both are monostable designs that return the valve to its home position when the pilot signal is removed. A mechanical spring resets the valve independently of the system pressure, even during a complete loss of air supply. An air spring utilizes the system pressure as the reset medium and will fail if system pressure drops. Therefore, only mechanical spring returns are suitable for safety functions requiring a defined fail-safe position.
AIRTEC offers two explosion protection concepts. Fully certified ATEX versions compliant with Directive 2014/34/EU (Equipment Category 2, suitable for Zone 1/21 and above) are available for selected product lines. Additionally, we offer versions without an inherent potential ignition source. While these do not carry an official ATEX mark, they have been verified via ignition hazard assessment for safe use in Zones 1, 2, 21, and 22 across all explosion groups. The right choice depends on the plant operator's zone classification. Please contact us directly with your specific requirements.
All AIRTEC valves are rated for compressed air according to ISO 8573-1:2010, Class 7:2:4 (filtered, oil-free, and dried). Please note that the pressure dew point must be at least 10 °C below the lowest ambient temperature encountered. Internal condensation leads to corrosion and seal damage, and can cause the valve to freeze at sub-zero temperatures. For applications involving unavoidable oil content or aggressive media, specialized product series featuring FKM (Viton) seals are available.
