The Madas FRG/2MBLZ is a direct-operated gas pressure regulator with compensated obturator.
2MBCL versions, a more compact version, are preferable for smaller applications.
It can be equipped with the following safety devices and accessories:
- Inlet filter: keep dust and deposits in the pipe.
- Outlet over pressure shut off device: (OPSO) it stops the gas flow when the regulator outlet pressure goes up the device
setting value. - Relief valve: it vents outside small quantity of gas in case there are downstream regulator over-pressure. That exhaust it is convoyed outside in case of installation in environment with bad ventilation.
- Outlet low pressure shut off device: (UPSO) it stops the gas flow when the regulator outlet pressure goes down the device setting value. It closes even if there is no inlet pressure.
- Outlet pressure test point.
