Flanged
DIRECT OPERATED GAS PRESSURE REGULATOR WITH COMPENSATED OBTURATOR TYPE RG/2MCS - RG/2MBZ
DESCRIPTION
Direct-operated gas pressure regulator with
compensated obturator.It can be equipped with the following safety
devices and accessory:
• OPSO: Outlet over pressure shut off
device (only RG/2MBZ): 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 overpressure.That exhaust it is convoyed
outside in case of installation in environment with bad ventilation
• UPSO: Outlet low pressure shut off
device (only RG/2MBZ): 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.Reference standard EN 88-2 - 334
In conformity with: 97/23/EC PED Directive 2014/34/EU ATEX Directive (ex 94/9/EC)
