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.
- Mounting position FABA

Bellow seal out of media flow path. Especially for pulsating, turbulent flow directly behind
pumps, elbows, junctions etc.
5.2 Installing valves with butt weld ends
Please note that only qualified persons using appropriate equipment and working in
accordance with technical rules are allowed to install fittings by welding.
The responsibility for this lies with the system owner.
Refer to the data sheet for information about the shape of the butt weld ends.
The valves must be welded in closed position.
ATTENTION !
- Remove flange covers if present.
- The interior of valve and pipeline must be free from foreign particles.
- Note installation position with reference to flow, see mark on valve.
- 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.
- Connection flanges must mate exactly.
- Connecting bolts for pipe flanges should be mounted preferably from the
counter flange side (hexagon nuts from the valve side).
At DN15-32: If valves should be mounted directly to valves, the upper flange
connecting bolts should be preferably executed with studs and hexagon nuts on
both sides.
- Valve mountings such as actuators, handwheels, hoods 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.
- Valves can be installed with the stem pointing in any direction, but the prefered
stem position is vertical.
- Valves should be installed upside down only, if the medium being handled is
clean.
- Keep the thread and shaft of the stem free from paint.
- Centre gaskets between the flanges.
