The safety kit for METHANE, LPG or CO is composed of one sensor for

detection and one solenoid valve. It allows to detect the presence of

gas in the house when its concentration is higher than the set limit

values (which are well below the dangerous limits set for the same

gases). An optical/acoustical signal in the sensor indicates the presence

of an alarm and the sensor controls the solenoid valve to make it close.

The solenoid valve has an upper button (n.2) for manual resetting of

the device and the subsequent re-connection of the user point to the

line. In the normally open version, the solenoid valve has also a side

button (n.1) for manual closing. This last function is very useful in case

of maintenance on the plant as it allows only partial disconnection of

the line.
