The following points should be taken into account besides the general principles governing
installation work:
CE-marking

Bj. Year of manufacture
According to the Pressure Equipment Directive table 6, annex II, valves without safety
function are only allowed to bear the CE-marking DN32 onwards.
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 spindle pointing in any direction, but the
prefered spindle position is vertical.
- Valves should be installed upside down only, if the medium being handled is
clean.
