5 Installation
The Type 42-24 and Type 42-28 Regulators
are designed for installation in the high
pressure (flow) line of the plant.
The Type 42-24 and Type 42-28 Regulators
are designed for installation in the low pres-
sure (return flow) line of the plant.
Î Choose a place of installation that allows
you to freely access the regulator even af-
ter the entire plant has been completed.
Î Install a strainer (e.g. SAMSON
Type 2 N) upstream of the regulator (see
section 5.2).
Î Flush the pipeline thoroughly before in-
stalling the regulator to ensure that any
sealing parts, weld spatter and other im-
purities carried along by the process me-
dium do not impair the proper function-
ing of the valve, above all the tight shut-
off.
Î The direction of flow must match the di-
rection indicated by the arrow on the
body.
NOTICE
Incorrectly installed regulator
The pressure regulator can be dam-
aged.
− Make sure the regulator is installed
free of stress.
− Do not attach supports (if required)
directly to the valve or actuator. At-
tach the supports near to the con-
necting flanges.
− Observe permissible mounting po-
sition.

the valve in the direction indicated by the ar-
row.

Connect the actuator to the valve bottom sec-
tion using the coupling nut (11).
