Important information
Possible malfunction or safety related incident
1
Disregarding these instructions may bring serious or
harmful consequences.
Failure to comply with these user instructions will render
the manufacturer‘s guarantee and liability null and void.
Unless otherwise agreed, the manufacturer‘s general
terms and conditions of sale shall apply.
2
Always observe system safety instructions
when preparing for and performing the repair
procedure.
Potential hazards and their sources are under the operator‘s
influence. The operator must observe national and interna-
tional environmental regulations for control valve removal
from the pipe and cleaning. Permissible exposure limits
must be maintained, appropriate personal protective equip-
ment must be used and service personnel must be properly
instructed in performing the repair procedure.
3
Make sure the pipeline is depressurized an in
ambient state, also a suitable rigging (e.g.
Endless Sling) and securing devices (e.g. Vee Trough
with Stands / Vise) are readily available.
Remove the valve / actuator from the pipeline in a depres-
surized and ambient state. Failure to do so can cause seri-
ous personal injury.
The control valve is not equipped with integral stands,
therefore guard against the valve from tipping over. Bodily
injuries can be the result. Use appropriate clamps, block-
ing or other stabilizing support. Attachment to overhead
crane can ensure stability.
4
Confirm that you have the required spare parts at the site.
Not having the full complement of parts, accessories and
tools can slow or stop repair work.
5
Confirm that you have the required tools avail-
able to manage the disassembly and reassembly
(Special Tools on request !).
Improper tools and / or improper use of tools can result
in personal injury or damage to the parts.
6
Review the serial plate information to identify the actua-
tor. The serial number and the part numbers needed are
required when ordering spare parts.
A serial plate used for product identification is attached on
every valve / actuator (See Section 3: Product Identifica-
tion).
7
Check all parts for damage such as scoring, deformities,
corrosion or overexpansion.
If in doubt, replace faulty parts.
Never reuse gaskets.
