The valve closes when the flow rate exceeds
the adjusted set point.

1)
The materials used in the regulator are also
resistant to high concentrations of glycol.
Nevertheless, glycol reacts when it comes into
contact with metals and causes acids to form.
We cannot prevent this reaction. Therefore,
prevent it by using suitable inhibitors.
2)
Suitable for air and nitrogen with diaphragm
Luft and seals made of FKM and PN 25
version
Noise emission
SAMSON is unable to make general state-
ments about noise emission as it depends on
the regulator version, plant facilities, process
medium and operating conditions.
Risk of hearing loss or deafness due to loud
noise.
Wear hearing protection when working near
the regulator.
The Type 45-9 Regulator is not a safety
valve. If necessary, a suitable overpressure
protection must be installed on site in the
plant section.
