Installing The Regulator; Cleaning The Pipeline; Testing The Regulator - Samson 43-2 Mounting And Operating Instructions

Installation
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 valve with flanges before
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.

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.
