7.2 adjusting the flow quantity
Screw the sampling bottle (item 9) into the
bottle adaptor (item 6). loosen the lock nut
(item 5). the flow quantity can now be adjusted
to the user's specific requirement by turning
the grub screw (item 4) in the desired direction,
and then locking it with the lock nut.
8 Notes oN daNGers duriNG iNstallatioN,
operatioN aNd maiNteNaNce
Safe operation of the valve is only guaranteed if it
has been correctly installed, commissioned and
maintained by qualified personnel (see 'Qualified
personnel'), taking into account the warning
information of these installation and maintenance
instructions. in addition, compliance with the
general installation and safety regulations for the
pipeline or plant construction, together with the
correct use of tools and protective equipment,
must be ensured.
WarNiNG
The installation and maintenance instructions
must be strictly followed when any work is carried
out on the valve or when handling the valve. Non-
observance can result in injuries or damage to
property.

9 operatioN

typical sampling:
1. Screw the sample bottle (item 9) into the
bottle adaptor.
2. Open the padlock (item 10) and remove the
safety pin.
3. turn the dead man's lever (item 2) anti-
clockwise as far as the preset stop (limit
adjustment, see Section 7.2). this lifts the
valve spindle and the medium flows through
the bottle adaptor into the sample bottle.
4. Watch the sample bottle closely at all times
during filling.
WarNiNG
The sample bottle must not be overfilled!
5. Release the dead man's lever when the
required filling quantity is reached. When
the lever is released, it automatically travels
back to the normal position.
6. unscrew the sample bottle and pass the
sample to the test station.

no routine maintenance or lubrication is
required. However, for systems with high
temperatures, an inspection for leakage at
the flanges should be carried out shortly after
installation. the large difference between the
temperature-related expansions of PfA and
metals can result in cold flow. tightening the
bolts once again will rectify this problem. this
process may possibly have to be repeated
several times.
WarNiNG
Before any dismantling or maintenance work is
carried out, the medium in the (depressurized!)
pipeline must be drained off and the pipeline
flushed, so that there is no longer any danger for
the operator/fitter.
When sampling clean, liquid products, no
cleaning is normally required.
in any case, if the bottle adaptor or the seat
assembly of the valve do become soiled
(crystallizing medium), the bottle adaptor can
be dismantled and cleaned as follows:
1. loosen the screw (item 7) and remove the
claw (item 7a).
2. the bottle adaptor (item 6) can now be
unscrewed.
3. Clean the adaptor/seat assembly (item 1)
and check the upper face of the O-ring; this
must be replaced if defective.
4. Screw the adaptor into the SAPRO body and
secure it with the claw (items 7, 7a).
cleaning agents
the cleaning agents recommended by the
internal works department should be used.
material compatibilities should be checked
before cleaning starts.
