Ex-proof pressure relief valves equipped with a solenoid pilot valve for venting or multiple pressure selections, certified for safe operation in hazardous environments with a potentially explosive atmosphere.

• Multicertification ATEX, IECEx, EAC, and PESO for gas group II 2G and dust category II 2D
• Multicertification ATEX and IECEx for gas group I M2 (mining)
• cULus North American certification for gas group C&D 

The flameproof enclosure of the solenoid prevents the propagation of accidental sparks or fire to the external environment. The solenoid designed to limit the surface's temperature within the classified limits.

Pressure relief valves equipped with a solenoid pilot valve for venting or multiple pressure selections, certified for safe operation in hazardous environments with a potentially explosive atmosphere.

• Certifications: ATEX or IECEx, II 1G Ex ia IIC, IIB, IIA surface zone 0, 1, and 2
• Certifications: ATEX or IECEx, IM2 Ex ia IMb, Ex ib IMb surface, tunnels, or mining plants

The valves electrically powered through specific "safety barriers" limiting the maximum current supplied to the solenoid.
