An explosion-proof solenoid valve must have a coil or enclosure that is able to contain any explosion originating from within the coil or housing and prevent any internal spark from igniting any combustible gas, vapors or particulates in the surrounding environment that could cause a much larger explosion.
There are a number of standards for classifying equipment for hazardous environments. The most common we see are; NEMA (National Electrical Equipment Manufacturers Association (USA)), IEC Ex (International Electrotechnical Commission Explosive (global)) and ATEX (ATmosphères EXplosibles (EU)). If you are purchasing an explosion-proof solenoid valve be sure you see one of these marks on the valve, which may vary depending on which standard was followed.
