Introduction
The technical and operational features of
the M Series, spring-loaded regulators,
make them ideal for applications requir-
ing 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, air, and other gas-
es, as long as the gas is fltered and does
not contain high percentages of benzol.
The MF, MN, and MR Series are in confor-
mity with the Pressure Equipment Direc-
tive PED 97/23/EC and are classifed under
Category IV maximum.
