MAG-3 DN32

MAG-3 DN32 Ex

Device group: Shut-off valves
Device type: MAG-3
Device model: MAG-3 DN32

MAG-3 is a swing valve in the Active Gas Safety System GX which automatically cuts off the gas supply and eliminates the risk of explosion of natural gas or propane-butane.

MAG-3 BIO versions are designed to work with landfill biogas or sewage treatment plants.

Area of application

  • in systems protecting gas installations: in gas boiler rooms, public buildings, etc;
  • external gas reduction and measurement points (working pressure up to 0.5 MPa);
  • cogeneration systems in sewage treatment plants or landfill sites (MAG-3 BIO models).


  • both open and closed positions do not require power supply – they are energy efficient (an electrical pulse of 12VDC with a duration of < 1s is only needed to close the valve);
  • insensitive to system supply voltage loss – its absence or momentary disappearance does not cause changes in gas flow through the valve;
  • resistant to any disturbances that may cause its accidental opening when closed (only conscious action by supervisors);
  • low force required to open the valve;
  • simple, cost-effective, reliable and lightweight design;
  • long life;
  • can be used in explosive atmospheres in accordance with the ATEX Directive.
