DOUBLE PROTECTION SAFETY VALVE

FEATURES:

ATTACHMENT: 1/4' 

All gas and flame returns are caused by the alteration of the balance between the exit speed of the mixture and the combustion speed. These valves prevent gas and flame return during welding work.

In compliance with European standard EN 730-1, the valves must mandatorily report:

• the valve model
• the manufacturer's name or abbreviation
• the reference standard number (EN 730-1)< /span>
• the functions provided by the valve (FA for flame arrest, NV for gas return)
• the type of gas (abbreviation) for which the valve was designed

The label color is also differentiated to further identify the valves immediately, thus facilitating installation and maintenance.
