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.
The A/140 Series is in conformity with
the Pressure Equipment Directive
PED 97/23/EC and is classified under
Category IV maximum.
