Gastight Valves

Closing the ventilation ducts and separating the clean and contaminated areas of the protected building is done safely with the help of Temet Gastight Valves. These valves retain their air tightness at substantial pressure differential, and can be manually operated or provided with electrical and electro-mechanical fail safe actuators.

Gastight valves are installed where ducts and channels penetrate the gastight protection line. When a gastight valve is open it allows airflow in or out. When the airflow has to stop the space will be isolated gastight and then the valve is closed. It is also possible to partly open the valve. In this case it is possible to regulate the airflow with the valve.

The KS series Gastight Valves are used in air ducts in Civil Defence and military shelters as well as in industrial facilities.
