Check valve MAG-3/DN80 in Ex design. The check valve consists of a MAG-3/DN100 valve and a set of counter flanges DN80.

The MAG-3/DN80 check valve is an actuator for the Active Gas Installation Safety System of type GX, designed to automatically shut off the gas supply in the event of an explosion hazard. It is a key device in systems protecting gas installations in boiler rooms, public buildings, and external reduction and measurement points. BIO versions are specifically adapted for operation with biogas from landfills or wastewater treatment plants.

This valve is characterized by a unique design that allows for energy-saving operation – it does not require power in the open or closed position. An electrical impulse of 12V (with a duration of less than 1 second) is only needed to close it. This feature, combined with immunity to voltage loss, ensures reliable operation even in the event of a power
