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.

Characteristics

CHARACTERISTICSThe BON TAS valve is a combination of BON GAS ball valve and the TAS thermic safety device. Rapid on/off 90° turn operation. Gas flow capacity complies with UNI EN 331 standard.
STANDARDSThe BON TAS ball valve complies with UNI EN 331 and the thermic safety device complies with DIN VP 301.
BON TAS ball valve is suitable for installations in conformity with UNI EN 1775.
HOW THE DEVICE WORKS

The TAS thermic safety device works in the event of fire as soon as the temperature reaches 100°C, so blocking the fuel gas flow for at least 60 minutes at 925°C temperature.
