MF, MN, and MR Series Pressure Regulators
Tartarini M Series spring-loaded regulators make them ideal for applications requiring sudden changes in capacity or where gas shutoff is solenoid-controlled as with domestic or industrial burners. These regulators can be used with natural, manufactured, propane, other gases, and air so long as they are filtered and do not contain high percentages of benzol.
MF, MN, and MR Series are in conformity with the Pressure Equipment Directive
PED 97/23/EC and are classified in Max. Category IV
