Mounting and assembly
5.3 Installation
The tested SAMSON regulator is delivered
as an assembled unit. Proceed as follows to
assemble the regulator and before start-up.
5.3.1 Installing the regulator
1. Close the shut-off valves upstream and
downstream of the regulator while the
regulator is being installed.
2. Remove the protective caps from the
valve ports before installing the valve.
3. Lift the regulator using suitable lifting
equipment to the site of installation. Ob-
serve the flow direction through the regu -
lator. The arrow on the valve indicates
the direction of flow.
4. Make sure that the correct flange gaskets
are used.
5. Bolt the pipe to the valve free of stress.
6. Slowly open the shut-off valves in the
pipeline after the regulator has been in-
stalled.
5.3.2 Cleaning the pipeline
We recommend additionally flushing the
pipeline without the installed regulator be-
fore start-up. In this case, install a suitable
length of pipe into the pipeline in place of
the regulator.
Î
Observe the mesh size of the upstream
strainer for the maximum particle size.
Use strainers to suit the process medium.
Î
Check the strainer for dirt each time the
pipeline is flushed and clean it, if neces -
sary.
