Installation
5.3 Final installation
Tested SAMSON regulators are delivered as
assembled units. The activities listed below
are necessary for installation and before
start-up of the regulator.
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 valve using suitable lifting equip-
ment to the site of installation. Observe
the flow direction through the valve. 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 valve 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.
