Support or suspension
Note
The plant engineering company is responsi-
ble for selecting and implementing a suitable
support or suspension of the installed regula-
tor and the pipeline.
5-2
Depending on the regulator version and
mounting position, the valve, actuator and
pipeline must be supported or suspended.
NOTICE
!
Risk of regulator damage due to incorrect
support.
Î Do not attach supports to the valve, to
moving parts on the actuator or to the
control lines.
Î Contact SAMSON if the mounting posi-
tion differs from the standard mounting
position.
Control line kit
After the actuator has been mounted, attach
the supplied high-pressure control line to the
regulator (see the 'Design and principle of
operation' section).
A control line kit for tapping pressure at the
valve body is available as an accessory part
from SAMSON (u T 3095).
Tip
Needle valves, compensation chambers and
compression-type screw fittings can be sup-
plied as required. These accessories are list-
ed in T 3095.
u
Compensation chamber
A compensation chamber (18) is required
for liquids above 150 °C as well as for
steam. Install the compensation chamber at
the highest point of the pipeline. The mount-
ing position of the compensation chamber is
indicated by an adhesive label on the cham-
