Installation
5.3 Installation
SAMSON regulators are delivered as as-
sembled units. The activities listed below are
necessary for installation and before start-up
of the regulator.
NOTICE
!
Risk of regulator damage due to the use of
unsuitable tools.
Î Only use tools approved by SAMSON
(see 'Tools' in Annex).
NOTICE
!
Risk of regulator damage due to exces-
sively high or low tightening torques.
Observe the specified torques when tighten-
ing regulator components. Excessive tighten-
ing torques lead to parts wearing out more
quickly. Parts that are too loose may cause
leakage.
Î Observe the specified tightening torques
(see 'Tightening torques' in Annex).
NOTICE
!
Risk of regulator damage due to the use of
unsuitable lubricants.
Î Only use lubricants approved by
SAMSON (see 'Lubricants' in Annex).

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 of regulators with flanges be-
fore installation.
3. Observe the flow direction through the
valve. The arrow on the valve indicates
the direction of flow.
4. Make sure that the correct 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.
