Gas solenoid valve, Pressure switches, Safety box
The gas solenoid valves (literally called gas safety solenoid valves) are usually associated with gas detection controllers in boiler rooms or all installations using gas burners. They guarantee the gas supply cutting by lack of voltage, with their operation in a positive safety mode. In addition to the gas solenoid valves, we offer a whole range of accessories for AIR/GAZ lines, such as pressure switches, pressure gauges, or safety boxes.
The ELK600 low-pressure manual reset gas solenoid valve is used for pressures below 600 mbar. It is a positive safety solenoid valve. The lack of voltage triggers the solenoid gas valve. It is then necessary to act manually to make the device return to its initial state.
- Low-pressure manual reset gas solenoid valve (Maximum pressure 600 mbar)
- F/F gas threaded connections (3/8" to 2"), flanged PN16 UNI2223 (DN65 to DN150)
- Power supply: 230V (On request: 110V - 50/60 Hz / 12-24 V - AC/DC)
- Fast opening/closing time: less than 1 second
- Limit switch possible only on request
The ELK900 high-pressure gas solenoid valve with manual reset is used for pressure up to 6 bar. It is a positive safety solenoid valve: the solenoid valve is closed when there is no current. Once triggered, manual intervention is necessary to reset the solenoid valve (opening of the solenoid valve) so that it returns to its initial state.

- Limit switch possible only on request
The gas solenoid valve class A EN161 ELK700 is an automatic low-pressure gas safety device (maximum pressure 360 mbar). It is a normally closed solenoid valve, so it remains closed when there is no power. As soon as the power supply returns, it will automatically open to let the gas through.

- Complies with the EN161 standard and approved by GASTEC PIN 63AQ1350
The high-pressure gas solenoid valve ELK800 is a gas safety device for pressures up to 6 bar. It is a normally closed solenoid valve, which means it remains closed when there is no power. As soon as the power supply comes back on, it opens automatically to let the gas through.

The AIR/GAZ pressure switch C6097 controls the minimum and maximum pressures of gaseous or air fuels for low-pressure gas installations (below 500 mbar). It also can be used to monitor the clogging level of fan air filters. A relay with changeover contact transmits the information to the safety device (gas solenoid valve).
- AIR/GAZ low-pressure switch (maximum pressure 500 mbar)
- Positive pressure tapping: RP 1/4" threaded - Pressure tapping for differential pressure: RP 1/8" threaded
- Setpoint accuracy: ±15% of the total scale value
- Switching capacity 230V/5A (resistive load)
- Materials: cast aluminum, polycarbonate, and polybutylene
The FEMA pressure switch DWR controls the pressure of gaseous, vapors, or air fuels in high-pressure systems up to 250 bar. The device is very accurate, factory adjusted and set, and can withstand extreme temperatures. A changeover relay transmits the information to the safety device (gas solenoid valve).
- FEMA high-pressure switch (up to 250 bar)
- Application: steam, hot water, combustible gases, fuel liquids
- DIN connection according to IEC 529
- High measuring accuracy for maximum safety
- Robust, seawater-resistant die-cast aluminum housing
The BSVD safety box aims to receive the gas valves of dams or the safety gas solenoid valves. This box is manufactured in steel with red epoxy paint offering strong resistance to corrosion and bleaching. It can thus be used for all applications and installations.
- Safety box available in 6 sizes
- Red color for high visibility even from a distance
- Made of sheet steel material and equipped with a plexiglass window
- High resistance to corrosion and bleaching
- Ice-breaking hammer available as an accessory
Safety gas solenoid valve – operation
A gas safety valve, or gas solenoid valve is a required unit for any gas installation. Once a gas leak is detected, the gas detection controller will shutdown the power supply of the gas solenoid valve through a closed relay. This lack of voltage will then close the gas safety valve (EN161 standard).
All of our safety valves include an ATEX solenoid coil and are available with several different voltage from 12 V to 240 VAC. The 240 VAC units are available in stock.
Manual or automatic solenoid valve
There are two types of electronic gas valves: the manual solenoid valve and the automatic safety valve.
Manual reset safety valve
A manual reset safety valve automatically turns off (shutdown of the solenoid valve) through a lack of voltage. It remains closed until the operator comes to reset the solenoid valve with manual override. This is usually a push-button or a lock system to trigger in order to release the valve shutdown.
Automatic safety valve
As for the manual reset solenoid valve, an automatic safety valve is a safety unit that shutdowns through a voltage lack. Contrary to the manual reset valve, the automatic gas solenoid valve unlatches and opens once the voltage is back. Thus the shutdown of the gas valve is not self-fixed.
Air/gas line accessories
Shut-off or relief valve
Relief valves are the first elements of an AIR/GAS line. They are available with or without locks. This very important safety unit enables the gas supply shutdown on a strategic location.
Gas pressure switch
A gas pressure switch is a safety unit too. They control gas presence (mini gas pressure switch) or gas overpressure (maxi gas pressure switch) and act directly on the system safety loop…
Safety box
The best location for the general gas solenoid valve is outside the building, protected inside a safety box. Thanks to its color (red) and its key lock system, the safety box is protected against the weather and malicious behaviors.
