Set point adjustment

The pressure regulator is adjusted at the
factory to the set points listed in the table.
However, you can change them by turning
the set point adjuster (6).
When pressure gauges are installed in the
connected pipelines, you can adjust the de-
sired set point directly while monitoring the
corresponding pressure gauge.
When no pressure gauge is installed, use the
adjustment diagram to adjust the set point.
1. Undo the lock nut to allow the set point
adjuster to move freely.
2. Determine the difference between the
fixed set point (Table 1) and the required
set point. Turn the set point adjuster the
required amount of turns as specified in
Fig. 3.
Any subsequent change in set point can
be also be made by determining the re-
quired number of turns using the specifi-
cations listed in the Set point change per
turn row.
3. Secure the setting with the lock nut.
