Installation
3. Remove the protective caps from the
valve ports before installing the valve.
4. Lift the valve using suitable lifting equip-
ment to the site of installation (see infor -
mation under 'Lifting the valve' in the
'Shipment and on-site transport' section).
Observe the flow direction through the
valve. The arrow on the valve indicates
the direction of flow.
5. Make sure that the correct flange gaskets
are used.
6. Bolt the pipe to the valve free of stress.
7. Attach a support or suspension on the
valve, if necessary.
5.4 Testing the installed valve
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Valves and pipelines are pressure equipment
that may burst when handled incorrectly.
Flying projectile fragments or the release of
process medium under pressure can cause
serious injury or even death.
Before working on the control valve:
Î
Depressurize all plant sections affected
and the valve (including the actuator).
Release any stored energy.
Î
Drain the process medium from all the
plant sections concerned as well as the
valve.
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. Additionally, a loud noise may briefly
occur through the sudden venting of the
pneumatic actuator or pneumatic valve ac
-
cessories not fitted with noise-reducing fit -
tings. Both can damage hearing.
Î
Wear hearing protection when working
near the valve.
Risk of personal injury due to exhaust air
being vented.
While the valve is operating, air is vented
from the actuator, for example, during
closed-loop operation or when the valve
opens or closes.
Î
Wear eye protection when working in
close proximity to the control valve.
Risk of personal injury due to preloaded
springs.
Actuators with preloaded springs are under
tension.
Î
Before starting any work on the actuator,
relieve the compression from the pre-
loaded springs (see associated actuator
documentation).
