Preparation For Installation; Mounting - Samson 2404-2 Mounting And Operating Instructions

5.2 Preparation for installation

Before installation, make sure the following
conditions are met:
− All the components of the regulator are
clean.
− All the components of the regulator and
piping are not damaged.
− Install a strainer upstream of the input
pressure regulator.
− The data on the nameplates (type desig-
nation, valve size, material, pressure rat-
ing and temperature range) match the
plant conditions (size and pressure rating
of the pipeline, medium temperature
etc.). See the 'Markings on the device'
section for nameplate details.
− The requested or required additional fit-
tings (see the 'Design and principle of
operation' section) have been installed or
prepared as necessary before installing
the valve.
Proceed as follows:
Î Lay out the necessary material and tools
to have them ready during installation
work.
Î Flush the pipeline before installing the
regulator.
The plant operator is responsible for
cleaning the pipelines in the plant.
Î Check any mounted pressure gauges to
make sure they function properly.

5.3 Mounting

Î See Fig. 5-2.
Tested SAMSON regulators are delivered as
assembled units. The activities listed below
are necessary for installation and before
start-up of the regulator.
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 tools.
Î Only use tools approved by SAMSON
(see 'Tools' 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).
