Installing The Regulator; Cleaning The Pipeline; Testing The Regulator - Samson 2357-3 Mounting And Operating Instructions

Installation
5.3.1

Installing the regulator

1. Close the shut-off valves (6.1 and 6.2) in
the pipeline while the valve is being in-
stalled.
2. Take the regulator out of the packaging.
3. Lift the regulator to the site of installation.
Observe the flow direction through the
regulator. Markings on the regulator in-
dicate the direction of installation.
4. Bolt the regulator to the pipeline free of
stress.
5. 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 integrated
strainer for the maximum particle size.
Î Check the strainer filters for dirt each
time the pipeline is flushed and clean
them, if necessary.

5.4 Testing the regulator

DANGER
!
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Regulators and pipelines are pressure equip-
ment that may burst when handled incor-
rectly. Flying projectile fragments or the re-
lease of process medium under pressure can
cause serious injury or even death.
Before working on the regulator:
Î Depressurize all plant sections concerned
and the regulator.
Î Drain the process medium from all the
plant sections concerned as well as the
valve.
Re
DANGER
!
Risk of personal injury due to process me-
dium escaping.
Î Do not start up the regulator until all
parts have been mounted.
WARNING
!
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or flashing)
may occur during operation caused by the
process medium and the operating condi-
tions.
Î Wear hearing protection when working
near the regulator.
