Bon Tas

Ball valve for fuel gas with thermic safety device

The Bontas series is a range of valves equipped with a particular thermal safety device which intervenes in case of fire. As soon as the temperature of 100 ° is reached, the device blocks the escape of gas for a minimum of 60 minutes at a temperature of 925°.

The Bontas series ball valves meet the requirements contained in the EN 331 standard and are suitable for systems in accordance with the UNI EN 1775 standard.
The TAS thermal device can be supplied coupled with the ball valve or separately.

Refer to specific national/international standards, where existing, for countries others than Italy.
