TGSA-025-1" IT/ET, heat-activated shut-off device

The thermal shut-off devices of the TGSA series interrupt the gas flow in the event of a fire. The TGSA closes automatically as soon as a certain temperature is reached (approx. 95°C), it closes before the functionality of parts of the gas system is affected. Unburned gas cannot escape and thus, possible fires will not be made worse by escaping gas and explosions become impossible. The thermal shut-off device can be used up to 925°C. Even at this temperature the TGSA guarantees tightness for 1 hour. When the temperature falls from 925°C to room temperature, a leak rate of < 1 can be ensured. To achieve the highest possible protection, the TGSAs should be connected directly before the fitting, such as mains shut-off, measuring and control devices or gas devices.
