5.4 Installing valves with limit switches
The valves with limit switches must be connected up as shown in the plans of the plant on
the basis of their working principles.
6.0 Putting the valve into operation
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.
