Pushbutton valves are used when pneumatically operated SHEV systems are not only to be opened with CO2 in case of fire, but also ventilation is used. For daily ventilation, compressed air is used as the medium. When the corresponding button is pressed, the compressed air is directed to the pneumatic cylinder and opens or closes it. For electrical control, the pushbutton valves are also available with 12V/DC, 24V/DC or 230V/AV connection. Thus they behave like a solenoid valve and can be integrated into the building control system (keyword: Smart Home).

Pure ventilation systems (without priority connection for CO2) are actuated with the pushbutton valve TV N6-5/2, the pushbutton valve in the TV N6-7/3 version has a CO2 priority connection and is thus used in SHEV systems.

Please note that the "old" version with the type designation "TV 06" is not mechanically compatible with the new version "TV N6". So if you need a pushbutton valve as a replacement and want to install it in the existing valve box, it will not fit (the hole spacing for the pushbuttons has changed).
