Operating and installation instructions
Steam injector
5.0 Installation
5.1 General notes on installation
The following points should be taken into account besides the general principles governing
installation work:
- 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.
5.2 Installation position
(refer to Fig. 2 page 4)
The side-mounted arrow indicates the flow direction.
The injectors are preferably installed horizontally. With several parallel injectors, they have
to be installed in the same horizontal level. The same flow direction is preferred.
6.0 Putting the valve into operation
ATTENTION !
- Remove flange covers if present.
- The interior of valve and pipeline must be free from foreign particles.
- Steam line systems should be designed to prevent water accumulation.
- Lay pipelines so that damaging transverse, bending and torsional forces are
avoided.
- Protect valves from dirt during construction work.
- Valves must not be used to take external forces, e.g. they are not designed for
use as climbing aids, or as connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See data sheet for weights.
- Precautions against freezing should be taken as a matter of course in any
facilities susceptible to frost.
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.
