Operating and installation instructions
ARI-REYCO R / RL Series
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 the valve into operation, check material, pressure, temperature,
direction of flow and also check that the data of the valve are correct for the
plant
(refer to type test plate)
- Remove any test gag from cap and close opening with stopper.
- Remove protective caps and lever lock before putting the valve into operation
- Freezing, sticking or blocking of the safety valve must be avoided at all costs. If
necessary use a heating jacket and/or stainless steel bellow without a rupture
disk. (Note point „5.0 Installation“).
- When operating without a blow-off line, medium may spurt from the valve outlet.
Injury hazard!
- Blowing off may generate loud flow noise.
- Medium may be discharged from the ventilation or inspection hole in the spring
bonnet (safety valves with stainless steel bellows and heating valves)
Injury hazard!
- Hot vapour may be discharged if the spring bonnet is open.
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.
