Pressure Set Point In Type 42- 39 Flow And Pressure Regulator; Decommissioning - Samson 42-37 Mounting And Operating Instructions

Operation
3.2.3 Pressure set point in
Type 42- 39 Flow and
Pressure Regulator
Adjust the pressure set point at the nut (17).
While doing this, read the pressure off the in-
stalled pressure gauge on the downstream
side .
4
Turn the nut (17) clockwise to increase
the downstream pressure.
4
Turn the nut (17) counterclockwise to re-
duce the downstream pressure.

Decommissioning

Close the shut-off valves starting from the up-
stream side (high-pressure line).
CAUTION!
On performing any work on the regulator,
make sure the relevant section of the pipeline
is depressurized and, depending on the pro-
cess medium, drained as well.
For high temperatures, allow the regulator to
cool down to ambient temperature before
starting any work on it.
Interrupt or shut off the control line to avoid
any hazards which could be caused by mov-
ing parts.
As valves are not free of cavities, remember
that residual process medium might still be
contained in the valve.
We recommend to remove the valve from the
pipeline. Make sure that all the plant sections
connected to the control lines are also
depressurized. If this is not the case, shut off
the control lines.
