6.0 Putting the valve into operation
7.0 Care and maintenance
Maintanance and maintenance-intervals have to be defined by the operator according to
the requirements.
ATTENTION !
- Before putting the valve into operation, check material, pressure, temperature
and direction of flow.
- Regional safety instructions must be adhered to.
- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.
- Touching the valve when it is operating at high (> 50°C) or low (< 0°C) media
temperatures can cause injury.
Affix warning notice or protective insulation as appropriate!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- All works has been completed!
- The valve is in the correct position for its function.
- Safety devices have been attached.
ATTENTION !
- It is advisable to actuate the valve at least once a month.
- When used as an end-blockage, a safety precaution (e.g. plug-in disc, blind
flange etc.) is demanded by maintenance works.
