Samson 3222 Series - Mounting the Device

EB 5866 EN 5-3
Installation
Proceed as follows:
Î Lay out the necessary material and tools
to have them ready during installation
work.
Î Flush the pipelines.
The plant operator is responsible for clean-
ing the pipelines in the plant.
Î For steam applications, dry the pipelines.
Moisture will damage the inside of the
valve.
Î Check any mounted pressure gauges to
make sure they function properly.
Î When the valve and actuator are al-
ready assembled, check the bolted joints.
Components may loosen during trans-
port.
5.3 Mounting the device
The activities listed below are necessary to
install the valve and before it can be started
up.
Risk of valve damage due to excessively
high or low tightening torques.
Observe the specied torques when tighten-
ing control valve components. Excessive
tightening torques lead to parts wearing out
more quickly. Parts that are too loose may
cause leakage.
We recommend rst installing the valve into
the pipeline and mounting the actuator after-
wards.
Procedure to insulate cold systems
To insulate cold systems, we recommend to
proceed as follows:
1. Fill the plant and carefully rinse it.
2. Shut down the plant and let it heat up
until all the condensation water has dried
off.
3. Mount and insulate the intermediate in-
sulating piece (1990-1712).
Observe the following on installing the con-
trol valve:
Î Make sure that the electric actuator re-
mains accessible after installation.
Î Make sure that the plug stem can move
freely and does not touch the insulation.
Î Make sure that the actuator stem does
not touch the insulation.
The insulation thickness depends on the me-
dium temperature and the ambient condi-
tions. 50mm is a typical thickness.
