2 Notes on safety
This operating manual contains fundamental
information which is to be observed during installation,
operation and maintenance.
It must be read before installation and
commissioning!
For valves which are used in potentially explosive ar-
eas, see Section 3.
Installation, operation and maintenance are to be per-
formed by qualified staff.
The area of responsibility, authority and supervision of
the staff must be regulated by the customer.
General hazard symbol!
People may be put at risk.
Safety symbol! The ball valve and its
function may be put at risk if this safety
symbol is not observed.
It is imperative to observe warnings and signs attached
directly to the ball valve and they are to be kept fully
legible.
Non-observance of the notes on safety may result
in the loss of any and all claims for damages.
For example, non-observance may involve the follow-
ing hazards:
♦Failure of important functions of the valve/plant.
♦Risk to people from electric, mechanical and chem-
ical effects.
♦Risk to the environment through leaks of hazardous
substances.
2.1 Intended use
Richter sampling valves are pressure-maintaining com-
ponents in accordance with the Pressure Equipment
Directive (DGRL) for taking liquid samples.
The standard PA/F and PA/S are only intended for hor-
izontal installation (vertical installation only with special
adapter).
The valves are suitable for non-boiling liquids of group
1 in acc. with the Pressure Equipment Directive
(DGRL).
Solids can lead to increased wear, damage to sealing
surfaces or to a reduction in the service life of the valve.
In case of the valve is intended for operating data other
than those intended, the customer must carefully ex-
amine whether the design of the valve, accessories and
materials are suitable for the new application. (Please
consult the manufacturer).

Series PA/F, PA/S Page 6
9510-010-en Revision 18
TM 9549 Edition 11/2018
2.2 For the customer / operator
If a valve is used, the operator must ensure that
♦hot or cold valve parts are protected by the cus-
tomer against being touched
♦the valve has been properly installed in the pipe sys-
tem
♦the usual flow rates are not exceeded in continuous
operation.
♦an appropriate collection system is used to contain
drip leaks/leaks locally and harmlessly.
This is not the manufacturer's responsibility.
Loads caused by earthquakes were not allowed for in
the design.
Fire protection to DIN EN ISO 10497 is not possible
(plastic lining and plastic components).
2.3 Improper operation
The operational reliability of the valve supplied is only
guaranteed if it is used properly in accordance with
Section 2.1 of this operating manual.
The operation limits specified on the name
plate and in the pressure-temperature dia-
gram must under no circumstances be ex-
ceeded.
3 Safety notes for applications in potentially explosive areas
based on the Directive 2014/34/ EC (ATEX)
The valves are intended for use in a potentially explo-
sive area and are therefore subject to the conformity
assessment procedure of the directive 2014/34/EC
(ATEX).
As part of this conformity assessment, an ignition haz-
ard analysis to EN 13463-1 to satisfy the fundamental
safety and health requirements was conducted with the
following result:
♦The valves do not have any ignition source of
their own and can be operated both manually as
well as mechanically/electrically.
♦The valves are not covered by the scope of ap-
plication of the ATEX directive and therefore do
not need to be identified accordingly.
♦The valves may be used in a potentially explo-
sive area.
Supplementary notes:
♦Electric/mechanical actuators must be sub-
jected to their own conformity assessment to
ATEX.
It is imperative to observe the individual points of in-
tended use for application in a potentially explosive
area.
3.1 Intended use
Inadmissible modes of operation, even for brief
periods, may result in serious damage to the unit.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and
induced charges, mechanical and electric sparks) may
result from these inadmissible modes of operation; their
occurrence can only be prevented by adhering to the
intended use.
Furthermore, reference is made in this connection to
the Directive 95/C332/06 (ATEX 118a) which contains
the minimum regulations for improving the
occupational health and safety of the workers who may
be at risk from an explosive atmosphere.
A difference is made between two cases for the use of
chargeable liquids (conductivity < 10-8 S/m):
1. Chargeable liquid and non-conductive lining
Charges can occur on the lining surface. As a result,
this can produce discharges inside and outside the
valve.
a) Discharges inside the valve
However, these discharges inside the valve cannot
cause ignitions if the valve is completely filled with
medium.
If the valve is not completely filled with medium, e.g.
during evacuation and filling, the formation of an ex-
plosive atmosphere must be prevented, e.g. by su-
perimposing a layer of nitrogen. It is recommended
to wait 1 hour before removing the valve from the
plant in order to permit the elimination of static peak
charges.

Series PA/F, PA/S Page 7
9510-010-en Revision 18
TM 9549 Edition 11/2018
This means that, to safely prevent ignitions, the
valve must be completely filled with medium at all
times or else a potentially explosive atmosphere
must be excluded by superimposing a layer of inert
gas.
b) Discharges outside the valve
At the points where the non-conductive lining e.g.
protrudes on the sealing surfaces to the outside or
gets contact with the atmosphere on the outside, it
may lead to discharges from the lining to nearby
valves or attachments.
To safely avoid explosion hazards and accidents,
therefore, the atmosphere surrounding the valve
must not be explosive.
2. Chargeable liquid and conductive lining
No hazardous charges can occur as charges are
discharged direct via the lining and shell (surface re-
sistance <109Ohm, leakage resistance <106Ohm).
Static discharges of non-conductive linings are
only produced through the interaction with a
non-conductive medium and are therefore the
responsibility of the plant operator.
Static discharges are not sources of ignition
which stem from the valves themselves!
♦The temperature of the medium must not exceed
the temperature of the corresponding temperature
class or the maximum admissible medium tempera-
ture as per the operating manual.
♦If the valve is heated (e.g. heating jacket), it must be
ensured that the temperature classes prescribed in
the Annex are observed.
♦For safe and reliable operation, it must be ensured
with regular inspection intervals that the unit is
properly serviced and kept in a perfect technical
condition.
♦Increased wear to the valve can be expected with
the conveyance of liquids containing abrasive con-
stituents. The inspection intervals are to be reduced
compared with the usual times.
♦Actuators and electric peripherals, such as temper-
ature, pressure and flow sensors etc., must comply
with the valid safety requirements and explosion
protection provisions.
♦The valve must be grounded.
This can be achieved in the simplest way via the
pipe screws using tooth lock washers.
Otherwise grounding must be ensured by different
measures e.g. a cable link.
♦Attachments such as actuators, position controllers,
limit switches etc. must satisfy the relevant safety
regulations as regards explosion protection and, if
required, be designed in compliance with ATEX.
♦Special attention must be paid to the appropriate
safety and explosion protection notes in the respec-
tive operating manuals.
♦Plastic-lined valves must not be operated with car-
bon disulphide.
4 Safety note for valves, certified to Clean Air Act (TA Luft)
Certificate / Manufacturer Declaration Validity is de-
pendent on the operating instructions being read and
observed.
♦Carry out regular maintenance intervals and check
the tightness of the screw connections and tighten
as necessary.

TM 9549 Edition 11/2018
5 Transport, storage and disposal
For all transport work, observe generally
accepted engineering practice and the ac-
cident prevention regulations.
The valve is supplied with flange caps.
Do not remove them until just before instal-
lation. They protect the plastic surfaces
against dirt and mechanical damage.
Handle the goods being transported with care. During
transport protect the valve against impacts and colli-
sions.
Directly after receipt of the goods, the consignment
must be checked for completeness and any in-transit
damage.
Transport securing:
Set the star grip so that the stroke is limited to the min-
imum flow. The lever has a safety function and must
swing freely (dead man's position).
Transporting the valve using the lever is not permitted.
Do not damage paint protection.
5.1 Storage
If the valve is not installed immediately after delivery,
store them properly.
It should be stored in a dry, vibration-free and well-ven-
tilated room at as constant a temperature as possible.
Protect elastomers against UV light.
In general, a storage period of 10 years should not be
exceeded.
5.2 Return consignments
Valves which have conveyed aggressive
or toxic media must be well rinsed and
cleaned before being returned to the man-
ufacturer's works.
It is imperative to enclose a safety information sheet
/ general safety certificate on the field of application
with the return consignment.
Pre-printed forms are enclosed with the installation and
operating manual.
Safety precautions and decontamination methods are
to be mentioned.
5.3 Disposal
Parts of the valve may be contaminated with medium
which is detrimental to health and the environment and
therefore cleaning is not sufficient.
Risk of personal injury or damage to the
environment due to the medium!
♦Wear protective clothing when work is performed on
the valve.
♦Prior to the disposal of the valve:
▪Collect any medium, etc. which has escaped and
dispose of it in accordance with the local regula-
tions.
▪Neutralise any medium residues in the valve.
♦Separate valve materials (plastics, metals, etc.) and
dispose of them in accordance with the local regu-
lations.

Series PA/F, PA/S Page 9
9510-010-en Revision 18
TM 9549 Edition 11/2018
6 Installation
♦Examine valve for in-transit damage, damaged ball
valves must not be installed.
♦Before installation the valve and the connecting pipe
must be carefully cleaned to remove any dirt, espe-
cially hard foreign matter.
♦During installation, pay attention to the correct tight-
ening torque, aligned pipes and tension-free assem-
bly.
♦The lever must move freely (deadman's position).
Ensure that a remotely actuated actuator
cannot be accidentally switched on.
6.1 Flange caps and gaskets
Leave protective caps on the flanges until just prior to
installation.
Where there is a particularly high risk of damage to the
plastic sealing surfaces, e.g. if the mating flanges are
made of metal or enamel, PTFE-lined gaskets with a
metal inlay should be used. These gaskets are availa-
ble as accessories in the Richter range.
6.2 Direction of flow and
installation position
Installation is independent of the direction of flow.
The installation position is normally horizontal with the
bottle connection pointing vertically downwards (devia-
tions from this position require a special bottle connec-
tion). See Section 10.4 and 10.9.
6.3 Grounding
The valve must be grounded. This can be achieved in
the simplest way via the pipe screws using tooth lock
washers. One pipe screw per flange is underlaid with
toothed disks.
Upon customer request a set screw M6 is attached to
each flange with a hex nut and washer as an additional
earthing connection.
Otherwise grounding must be ensured by different
measures e.g. a cable link.
6.4 Test pressure
The test pressure PT of a valve must not exceed the
value of 1.5 x PS(PN) as per the identification of the
valve.
6.5 Star knob
The stroke and thus the pressure reduction and me-
dium flow can be influenced with the star knob.
Moreover, the star knob can be used to close the valve
like a manual valve.
It also served to enforce tightness in case of damaged
seat sealing surfaces or seized particles.
6.6 High-viscosity media /
Low operating pressure
With the version "design for high-viscosity media" the
changed operating limits acc. to the name plate must
be observed and the travel must be set according to the
setting instructions in Section 6.7.
6.7 Setting instructions
♦Press the sampling lever in the direction of the
valve.
♦Slowly turn the star knob counterclockwise until the
flow into the sampling bottle corresponds to the in-
tensity you want.
♦Release lever and lock the star knob in this position.
This procedure guarantees that with each further sam-
pling process (with the same internal pressure) the flow
of the sample into the bottle remains within the desired
range without any risk to the person taking the sample.
If the operating pressures vary, we recommend you for
safety's sake to turn the star knob after every sampling
operation clockwise again until it reaches zero point
(lever cannot execute any travel).

6.8 Needle adapter for PA/S DN25
When you use a stainless steel needle adapter for
PA/S DN25 make sure that you insert the flat gasket.
7 Operation
7.1 Initial commissioning
Normally, the valves have been tested for
leaks with air or water. Prior to initial oper-
ation check cover screws. For tightening
torques, see Section 1.2.
Unless otherwise agreed there could be residual
amounts of water in the flow section of the valve. This
could result in a possible reaction with the medium.
To prevent leaks, all connection screws should be
retightened after the initial loading of the valve with
operating pressure and operating temperature.
For tightening torques, see Section 1.2.
7.2 Improper operation and their
consequences
♦Crystallisation must be prevented, e.g. by heating.
Damage to the seat or cone would be inevitable.
In extreme cases a leak may occur.
♦Increased wear occurs in operation with solids con-
tents.
♦Violent opening or rapid filling may cause the bottle
to burst.
♦Non-observance of the pressure-temperature dia-
gram can lead to damage.
♦Do not transport the valve using the lever.
♦Do not use a lever extension as otherwise there is a
risk of damage.
♦At the customer's request, the middle hole in the
lever is drilled through. If the lever is then locked in
the lower hole to take samples and if, in addition, a
pin is inserted into the middle hole, it must be en-
sured that sampling does not take place acci-
dentally.

Series PA/F, PA/S Page 11
9510-010-en Revision 18
TM 9549 Edition 11/2018
7.3 Sampling (Standard)
♦Screw bottle into the bottle connection 226.
♦Check travel set on the star knob 963/1.
♦Lever 203 is in the dead man's position.
♦For sampling, lock lever in the top groove.
♦If it is requested that the lever is firmly locked, drill
through the middle hole and insert an additional pin
into the middle hole.
CAUTION! Sampling may also take place acci-
dentally.
♦Press in direction of valve.
♦Sampling can take place.
A lock is available from Richter as an option.
A device, screw fitting 917 for example, for the riskfree
discharge of the medium must be connected to the
venting connection. Sealing plugs are not allowed
because this results in overpressure in the bottle.
7.4 Shutdown
The local regulations are to be observed when disman-
tling the valve.
Prior to undoing the flange connection
ensure, that the plant is depressurised
and emptied.
Prior to starting any repair work, the valve
is to be thoroughly cleaned. Medium resi-
due may be in the valve even if it has been
properly drained and flushed.
After dismantling, immediately protect the valve flanges
against mechanical damage by using flange caps. See
also Section 6.1.
Make sure that a remote-controlled actuator cannot be
switched on by accident.
8 Malfunctions
♦Flange connection ball valve/pipe is leaking
Retighten the flange screws to a tightening torque
according to Section 1.2. If this does not remedy
the leak, the recommended torques may be ex-
ceeded by 10%.
If this also fails to stop the leak, dismantle and in-
spect the valve.
♦Flange connection body/seat or body/cover is leak-
ing
Retighten body screws. See paragraph "Flange
connection ball valve/pipe is leaking".
♦Packing is leaking
Bellows leaking.
Retighten safety packing and switch off plant as
quickly as possible and isolate pipe section with
valve.
♦Valve does not close tight
Loosen lock nut under the star grip and close the
valve by means of the star grip.

9 Maintenance
♦All repair work is to be performed by qualified per-
sonnel using the appropriate tools.
♦For the arrangement, designation and item numbers
of all parts of the valve, see Section 10.
♦Spare parts are to be ordered with all the details in
acc. with the valve identification.
♦Only original spare parts may be installed.
♦To prevent leaks, a regular check of the connection
screws should be made in line with the operating re-
quirements.
For tightening torques, see Section 1.2.
Make sure that when working on the
sampling valve it is drained.
See also Section 7.4.
