 FL
series regulators feature axial flow, simple seat and
counterbalanced valve. Thanks to their construction
features, they offer higher capacities with the same DN
and reduced overall dimensions. They assure high
accuracy of the regulated pressure even when the inlet
pressure is extremely variable. They can be used also as
"monitor" to be installed upstream of the regulator as
emergency device. The modular design of FL series
regulators allows the combination of a monitor and a
regulator through an intermediate stub-pipe (MFL series)
without interposing flanges and thus obtaining minimum
overall dimensions.
