5 Mounting and assembly

Valve and control thermostat can be assem-
bled before or after the valve has been in-
stalled in the pipeline. We recommend first
installing the valve without the control ther-
mostat into the pipeline.

5.1 Preparation for installation

Proceed as follows:
Î Flush the pipelines.
Note
The plant operator is responsible for clean-
ing the pipelines in the plant.
Note
Any impurities carried along by the process
medium may impair the proper functioning
of the regulator. We recommend installing a
strainer (e.g. SAMSON Type 1 NI) upstream
of the pressure reducing valve (see sec-
tion 6.3.1).
Î Check the valve and control thermostat to
make sure that they are clean and not
damaged.
Î Check to make sure that the type desig-
nation, valve size, material, pressure rat-
ing and temperature range of the valve
and control thermostat match the plant
conditions (size and pressure rating of
the pipeline, medium temperature etc.).
Î Check any mounted thermometers to
make sure they function.

NOTICE NOTICE
! !
Risk of overheating due to excessive ambient
temperatures or insufficient heat dissipation
when components are insulated.
− Do not include the regulator in the insula-
tion of the pipeline.
NOTICE
!
Risk of impaired functioning of the regulator
and leakage at the joint due to installation
under tension.
− Bolt the regulator to the pipeline free of
stress.
− If necessary, support the pipelines near to
the connections.
− Do not attach supports directly to the valve
or control thermostat.
