Gas solenoid valves
Here are gathered all of our manual or automatic reset gas solenoid valves (standard gas or biogas). These electronic gas valves are normally open or normally closed and have been designed to shut down a gas supply through lack of voltage thanks to their positive safety operation.

Manual or automatic reset gas solenoid valve
A Solenoid coil is a safety unit that shuts down (gas valve closing which shut down the gas supply) through lack of voltage. There are two different types of gas solenoid valves: automatic reset gas safety valves and manual reset gas safety valves.
Manual solenoid valves
A manual reset gas solenoid valve automatically shuts down (valve closing) through lack of voltage and remains closed until an operator resets the solenoid valve. This is usually performed with a push-button or a latch to trigger the reopening the solenoid valve.
Automatic solenoid valves
Just like a manual reset gas solenoid valve, the automatic gas solenoid valve is a safety unit which shuts down through lack of voltage. However, once the voltage comes back, the gas solenoid valve unlocks and opens. The gas solenoid valve closing is not self-contained.
Gas line accessories (sectional valve, gas pressure switch and safety box)
In addition to gas solenoid valves, we also offer a large range of AIR/GAS line accessories such as sectional valves (lockable or not), air/gas pressure switches with incremental pressure (low or high pressure), manometers and safety boxes to protect gas solenoid valves.
Sectional valve
A sectional valve is the first element in an AIR/GAS line. It is available in two versions: lockable or not. This safety unit is very important as it enables the gas supply shut down at a precise point. Without a sectional valve, it is sometimes required to shut down the gas supply at the reducing station for any repair which considerably increases the technical intervention cost: need to purge a large section.
Gas pressure switch
Gas pressure switches are also safety units at low or high pressure. They are designed to control the minimal presence of gas (mini gas pressure switch) or a gas overpressure (maxi gas pressure switch). They directly act on the installation’s safety loop.
Safety box
The logical approach would be for the gas safety valve to be implemented outdoors, thus avoiding any explosion risk in case of gas leak (at the connection point for example). A safety box – colored in red for a better view – protects safety units from the weather or bad behaviors (lock with key).
