2.4 Operating principle of a VGA-117 dosing regulator
The chlorine gas volume flow is adjusted by the dosing regulator.
This can be done manually or automatically with a servomotor.
VGA-117 dosing regulators can have a differential-pressure
regulator that reduces and regulates the injector vacuum to a
constant level to secure a constant and linear gas flow.
VGA-117-110 and VGA-117-190 dosing regulators operate without
a differential-pressure regulator. They achieve a constant and linear
chlorine gas flow under sonic flow conditions.
Dosing regulators without a differential-pressure regulator operate
with VGB injectors. VGB injectors have a higher performance but
require larger motive water flow and higher motive water
pressure. Dosing regulators without a differential-pressure regulator
do not comply with DIN 19606.
