Threaded
DIRECT OPERATED GAS PRESSURE REGULATOR FRG-RG/2MCS
DESCRIPTION
Gas pressure regulator with compensated obturator.
• FRG/2MCSH- RG/2MCSH= Filter regulators and Regulators WITHOUT safety shut
off device
• FRG/2MBH... - RG/2MBH... = Filter regulators and Regulators WITH safety shut off
device.
It can be equipped with the following safety devices and accessory:
• outlet over pressure shut off device (only 2MBH... versions): 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
• outlet low pressure shut off device (only 2MBH... versions): 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.
• inlet filter (only on FRG/2MBH...-FRG/2MCSH DN 15 - 20 - 25) Reference standard EN 88-2 - 334
