Europe, Middle East and

Africa Only

INSTALLATION

Personal injury or equipment damage, due

to bursting of pressure-containing parts may

result if this regulator is over-pressured or

is installed where service conditions could

exceed the limits given in the Specification

section and on the appropriate nameplate,

or where conditions exceed any rating of the

adjacent piping or piping connections.
To avoid such injury or damage, provide

pressure-relieving or pressure-limiting

devices to prevent service conditions

from exceeding those limits. Also, be sure

the installation is in compliance with all

applicable codes and regulations.
Additionally, physical damage to the regulator

could break the pilot off the main valve,

causing personal injury and property damage

due to bursting of pressure-containing parts.
To avoid such injury and damage, install the

regulator in a safe location.

Only personnel qualified through training and

experience should install, operate and maintain

a regulator. Before installation, make sure

that there is no damage to, or debris in, the

regulator. Also make sure that all tubing and

piping are clean and unobstructed.
• The regulator is installed on horizontal

pipeline. Version with slam shut, the

release relay is situated towards the

bottom (see schematic).

• Installation according to

EN12186 recommended.

• Install according to direction of fluid

flow (arrow).

• When assembling with adjacent elements

care must be taken not to create pressure

force on the body and the assembling

elements (bolts, O-rings, flanges) should be

compatible with the geometry and working

conditions of the equipment.

All interventions on the equipment should only be performed by qualified and trained personnel.
