DANGER
!
Risk of personal injury due to process me-
dium escaping under pressure.
Î First start up the regulator after mounting
all parts.
WARNING
!
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju-
ries.
Î Allow components and pipelines to cool
down or heat up.

gloves.
WARNING
!
Risk of personal injury due to pressurized
components and process medium escaping
under pressure.
Î Do not loosen the control line while the
valve is pressurized.
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
EB 2512 EN
process medium and the operating condi-
tions.
Î Wear hearing protection when working
near the valve.
WARNING
!
Crush hazard arising from moving parts.
Î Do not insert hands or fingers between
the set point springs while the regulator

Î Do not insert hands or fingers between
the pillars and set point springs while the
regulator is in operation.
Î Do not insert hands or fingers between
the spring plate and crossbeam while the
regulator is in operation.
Î Before starting any work on the regula-
tor, depressurize plant sections as well as
the regulator.
Before start-up or putting the valve back into
operation, make sure the following condi-
tions are met:
− The regulator is properly installed into
the pipeline (see the 'Installation' sec-
tion).
− The leak and function tests have been
completed successfully (see 'Testing the
regulator').
− The prevailing conditions in the plant
section affected meet the regulator sizing
requirements (see information under 'In-
tended use' in the 'Safety instructions
and measures' section).
