Adjusting The Set Point - Samson 2417 Series Mounting And Operating Instructions

Start-up and operation

6.3 Adjusting the set point

Î Refer to Fig. 3
Î The required upstream pressure is set by
turning the set point adjuster (6) using an
open-end wrench (up to DN 50 with
width across flats SW 19 and for DN 65
and larger with SW 24). The set point of
the stainless steel regulator must be ad-
justed using the rod included.
Î Turn the set point screw clockwise () to
increase the pressure set point.
Î Turn the set point screw counterclockwise
() to reduce the pressure set point.
The pressure gauge located on the upstream
pressure side allows the adjusted set point to
be monitored.
An initial adjustment of the set point can also
be made by changing the spring tension and
Table 7 until the distance x (see Fig. 8) is
reached.
Note
Note during initial set point adjustment that
only a rough set point adjustment is per-
formed by turning the set point adjustment
until the distance x is reached. The special
properties of the process medium and plant
are not taken into account in this case.
Check the pressure at the pressure gauge
downstream of the regulator for a precise set
point adjustment.
