Introduction
Construction and performance features
make the A/140 Series spring‑loaded
regulators the ideal choice in applications
involving sudden changes in capacity, or
where the gas shutoff is solenoid‑controlled
as with domestic or industrial burners.
These regulators can be employed with
natural, manufactured, and propane
gas as well as air as long as they are
adequately fltered and do not contain
high percentages of aromatics.
The A/140 Series is in conformity with
the Pressure Equipment Directive
PED 97/23/EC and is classifed under
Category IV maximum.
