Operation

7 Operation

Immediately after completing start-up or
placing the regulator back into service (see
the 'Start-up' section), the regulator is ready
for use.

Risk of burn injuries due to hot or cold

components and pipeline.

Regulator components and the pipeline may
become very hot or cold. Risk of burn inju

ries.

Allow components and pipelines to cool
down or heat up.

Wear protective clothing and safety
gloves.

Risk of personal injury due to pressurized

components and process medium escaping

under pressure.

Do not loosen the control line while the

valve is pressurized.

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.

Wear hearing protection when working

near the valve.

WARNING

Crush hazard arising from moving parts.

Do not insert hands or fingers between
the set point springs while the regulator

is in operation.

Before starting any work on the regula

tor, depressurize plant sections as well as

the regulator.
