Safety valve
1
General Notes of Safety
• Only use the valve:
- for the intended purpose
- in satisfactory condition
- with respect for safety and potential hazards.
• Always observe the installation instructions.
• Remove all protective covers and other transport safety devices directly before
assembly.
• In addition to the generally valid assembly guidelines, you must ensure that the
system must be de-pressurised before removal of the safety valve. Moreover,
the system must be drained and ventilated in the case of aggressive and corro-
sive media. The safety valve must have adjusted to room temperature.
• Faults that may impair safety must be addressed immediately.
• The valves are exclusively intended for the application area stated in these ins-
tallation instructions. Any other or further use is not valid as the intended use.
• The manufacturer's warranty shall be null and void if the sealed cover is
removed
• All installation work must be carried out by authorised specialist personnel only.
• These operating instructions do not replace any national regulations, regulati-
ons on accident prevention or local safety regulations. Such regulations always
have priority.
• All structural modifications of the valve are strictly prohibited. This applies in
particular to inserting drill holes or welding on other objects.
• The following points must be observed during all repair work:
- When carrying out repairs or maintenance work on automated valves, it
must be ensured that the power supply of the drives has been disconnected
reliably.
- Pressurised cushions of air in the system must be removed and the affected
pipelines drained. Before performing these steps, the operator must be aware
of the risks that can arise from residues of the operating medium.
- Appropriate and sufficient items of personal protection clothing must be
worn. These include protective shoes, safety goggles, protective gloves, etc.
- The system must be protected against restarting by appropriate measures
and means.
