Application Automatic exhaust valves type ATVC-100 are suitable for installations in multi-storey residential buildings, office blocks, hotels, schools etc., with a central exhaust air system. ATVC100 can be installed either in new or renovated buildings. Realisation The automatic exhaust valve is an air control unit controlled by an electric pilot switch. It is normally closed or slightly open to alow a basic air flow rate. Air is extracted at a higher operating rate only when the switch contact is closed. Operating When the circuit is closed, the electro-thermal drive heats up and causes the valve disc to open within 2 to 4 minutes (delay desirable during a brief stay in the room). Air is exhausted through the opening between the valve housing and the valve disc. The valve stroke (6 mm) is always the same, that is, the valve disc always moves from the minimum setting up to the maximum valve opening. In the minimum setting, the valve disc can either be closed or opened. Since the valve stroke is always the same, the operating air flow rate depends on the minimum setting and cannot be freely selected. After the interruption of the circuit, the valve remains open for after-ventilation for approx. 5 - 8 minutes before it starts to move back to its minimum setting slowly and silently.
