EURO-WEDI
®
- Planners / construction companies or operators are responsible for positioning and
installing products.
- The valves are designed for application, not influenced from weather.
- For application outside or in adverse environments like corrosion-promoting conditions
(sea water, chemical vapours, etc.), special constructions or protective measures are
recommended.
6.0 Putting the valve into operation
- Centre gaskets between the flanges.
- Reference for isolation: If media-temperatures < ambient temperatures - ask
manufacturer.
- It is forbidden to heat the valve to above its service temperature (see data
sheets), for instance by welding, grinding, etc.
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.
