5.0 Installation
5.1 General notes on installation
The following items should be taken into account besides the general principles governing

Year of manufacture (clear speech) (1. and 2. position of the serial-No.)
According to the Pressure Equipment Directive table 7, annex II valves are only allowed to
bear the CE-marking  Category I ( DN125 PN10,  DN65 PN16).
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.
Refer to data sheet for weights.
- Keep the thread and shaft of the stem free from paint.
- Centre gaskets between the flanges.
- Strainers or filters should be installed before the valves.
