Malfunctions

HON 5020 gas pressure regulator with HON 630 pilot

Malfunction

Possible causes

Correction

Leaks on the inside

Faulty actuator assembly dia-
phragm

Check the actuator assembly’s

diaphragm for damage

Faulty pilot diaphragm

Check the pilot’s

diaphragm for

damage

Faulty pilot piston

Check the pilot’s piston for damage

The flow restrictor’s screws are not

tightened properly

Check the flow restrictor’s screws

to make sure they have a tight fit

Unstable outlet pressure
behavior (oscillations)

The regulator is not being operated
with sufficient differential pressure

Increase the differential pressure
with the regulator

The actuator assembly’s diaphragm

is too soft

Check the actuator assembly’s

diaphragm; contact the manufac-
turer if necessary

Pilot not compatible with applica-
tion

Contact the manufacturer

The amplifying valve setting is not
correct
