6.1 installation
6.1.1 Preparation for installation
the dimensions of the valves have been chosen
so that the sampling valves can be clamped
between all current Din and AnSi flanges.
it should be noted here that sampling valves
designed for a specific flange standard no
longer fit other flanges.
Principal dimensions of the valves: refer to the
catalog page for data.
the flanges must meet the following
requirements:
- Cleaned and undamaged mating surface.
- the mating sections in the pipeline must be
to the same connection standard as the valve
which is to be installed.
- the appropriate flange bolt hole
arrangements in the various flange standards
and diameters allow the valve to be centered
by passing the flange bolts through the holes
in the flanges.
- the flange bolts must be centrally aligned in
the holes in the valve flanges.
6.1.2 Installation position
in accordance with Section 4.2.1 of these
installation and maintenance instructions,
the sampling valve can be installed either
horizontally or vertically, with certain
restrictions (an angle adaptor is required for
horizontal installation).
6.2 installation in the pipeline
the direction of flow is irrelevant with the
sampling valves. However, before the valve is
installed, a check should be made on whether
any special valve packings are required; for
more information see Section 6.2.3.
An SV valve is not a crowbar! Please do not use
it to force the flanges apart, as this would lead
to damage to the PfA coating and the seat. to
avoid damaging the PfA coating, the protective
covers should only be removed immediately
prior to installation.
WarNiNG
It is not advisable to use the valves for positioning
pipelines in new systems. Sparks which occur
during spot welding can damage the PFA coating.
Use adjusting pieces instead. Final welding of the
flange with the valve in position will lead to severe
damage to the mounting flange due to the high
temperature.

Always use all flange bolts, even on low
pressure systems. the valve should never be
pressurized if one of the four flange bolts is
missing.
6.2.1 Step-by-step installation
1. Remove the plastic protective caps.
2. Check the mounting flanges (items 11 and
12) for damage and soiling.
3. Check that the distance between flanges
matches the face-to-face dimension of the
sampling valve. before installing the valve
(items 1a and 1b), spread the flanges apart
sufficiently using a suitable tool.
4. Slide the valve between the opened flanges,
and at the same time insert the packings
(item D, if required, see Section 6.2.4)
between the sealing surfaces.
5. now insert the flange bolts through the
adjusting holes.
6. tighten the flange bolts hand-tight as the
tool holding the flanges apart is gradually
removed. make sure that the flanges remain
correctly aligned.
7. tighten all flange bolts in opposite pair
sequence. See Section 6.2.2 for tightening
torques.
8. Connect a vent hose or pipe to the bottle
adaptor vent port (8). the release opening
of the vent hose port shall be placed at a
position where it cannot harm the operator.
