If using a rundown tank, make sure that it is gravity driven and located
at a higher level than the actuator!
2. Commissioning
The medium and the valve can pose the following hazards:
• Critical operating conditions can cause impermissible levels
of noise and vibration.
Hearing loss, vascular and nerve problems, damage to joints and bones!
• Incorrect maintenance can result in the operating medium
escaping.
Danger of burns, freezing!
• The temperature of the operating medium is transferred to the
surface of the valve.
Danger of burns, freezing!
As these hazards can all be controlled by the plant operator,
the operator is obliged to comply with national and international
environmental regulations, install suitable protective measures
to ensure workplace requirements are satisfied, and to instruct
his employees accordingly.
Due to the risk of injury, it is prohibited to work between
the yoke/columns while the valve is in operation.
Once these hazards have been averted by adopting appropriate
protective measures, the valve can be installed and connected
in the piping. The following points should be noted:
• Flange connection:
Connection material (gaskets, bolts, nuts) are not part of the
scope of supply.
Locate gaskets in the centre of flanges, failure to do so can result in leaks and
increased noise levels.
If a completely installed piping is to be flushed or blown through for cleaning,
replace the control valve with a matching piece.
