General information Low consumption (0.7W), CROUZET /2 miniature solenoid valves comply with European Standards EN 5004 and EN 50020 relating to equipment operating in potentially explosive atmospheres. These intrinsically safe products are recommended for the chemical, petrochemical, gas and mining industries, etc. Important : These intrinsically safe miniature solenoid valves must be individually connected to an approved safety barrier. Placed in a safe zone, these barriers make it possible to supply intrinsically safe miniature solenoid valves installed in a hazardous zone. Hazardous Zone Non Hazardous Zone Category ia Ignition must not be provoked during normal operation, nor in the presence of a single fault, nor in the presence of a combination of faults.
