2 Notes on safety
This operating manual contains fundamental
information which is to be observed during installation,
operation and maintenance.
It must therefore be read before installation and
commissioning!
For valves which are used in potentially explosive
areas, see Section 3.
Installation, operation and maintenance are to be
performed 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 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 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
following hazards:
Failure of important functions of the valve/plant.
Risk to people from electric, mechanical and
chemical effects.
Risk to the environment through leaks of hazard-
ous substances.
2.1 Intended use
Richter sampling valves are pressure-maintaining
components in accordance with the Pressure
Equipment Directive (DGRL) for taking liquid samples.
The standard PA/F and PA/S are only intended for
horizontal installation (vertical installation only with
special adapter).
The valves are suitable for non-boiling liquids of group
1 in accordance with the Pressure Equipment
Directive.
Solids can lead to increased wear, damage to sealing
surfaces or to a reduction in the service life of the
valve.
The operator must carefully examine in the event of
operating data other than those provided whether the
designs of the valve, accessories and materials are
suitable for the new application (consult the
manufacturer).

Series PA/F, PA/S Page 6
9510-060-en Revision 17
TM 9549 Edition 07/2016
2.2 For the customer / operator
If a valve is used, the operator must ensure that
actuators which are retrofitted are adapted to suit
the valve
hot or cold valve parts are protected by the
customer against being touched
the valve has been properly installed in the pipe
system
the usual flow rates are not exceeded in continu-
ous 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
identification plate and in the pressure-
temperature diagram must under no
circumstances be exceeded.
3 Safety notes for applications in potentially explosive areas
based on the Directive 2014/34/EU (Atex)
The valves are intended for use in a potentially
explosive area and are therefore subject to the
conformity assessment procedure of the directive
2014/34/EU (ATEX).
As part of this conformity assessment, an ignition
hazard analysis to EN 13463-1 to satisfy the funda-
mental 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
application of the ATEX directive and therefore
do not need to be identified accordingly.
The valves may be used in a potentially
explosive area.
Supplementary notes:
Electric/mechanical actuators must be subject-
ed to their own conformity assessment to
ATEX.
It is imperative to observe the individual points of
intended use for application in a potentially explosive
area.
3.1 Intended use
Improper 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 improper 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 occupa-
tional 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 the
valve. However, these discharges cannot cause
ignitions if the valve is completely filled with medi-
um.
If the valve is not completely filled with medium,
e.g. during evacuation and filling, the formation of
an explosive atmosphere must be prevented, e.g.
by superimposing 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
9510-060-en Revision 17
TM 9549 Edition 07/2016
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.
2. Chargeable liquid and conductive lining
No hazardous charges can occur as charges are
discharged direct via the lining and shell (surface
resistance 109Ohm, leakage resistance 106
Ohm).
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 temper-
ature as per the operating manual.
If the valve is heated (e.g. heating jacket), it must
be ensured that the temperature classes pre-
scribed in the Annex are observed.
To achieve safe and reliable operation, it must be
ensured in inspections at regular intervals that the
valve is properly serviced and kept in technically
perfect order.
Increased wear to the valve can be expected with
the conveyance of liquids containing abrasive
constituents. The inspection intervals are to be
reduced compared with the usual times.
Actuators and electric peripherals, such as
temperature, 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 other
action, e.g. cable bridges.
Attachments such as actuators, position control-
lers, 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 re-
spective operating manuals.
Plastic-lined valves must not be operated with
carbon disulphide.
4 Safety note for valves, certified to German Clean Air Act (TA
Luft)
Certificate / Manufacturer Declaration Validity is
dependent on the operating instructions being read
and observed.
Perform maintenance at regular intervals and
check the screw connections relevant to leak-
tightness and, if necessary, retighten them.

9510-060-en Revision 17
TM 9549 Edition 07/2016
5 Transport, storage and disposal
It is imperative, for all transport work, to
observe generally accepted engineering
practice and the accident prevention
regulations.
The valve is supplied with flange caps. Do not
remove them until just before installation.
They protect the plastic surfaces against dirt
and mechanical damage.
Handle the goods being transported with care. During
transport the valve must be protected against impacts
and collisions.
Directly after receipt of the goods, the consignment
must be checked for completeness and any in-transit
damage.
Transport securing device:
Set the star knob so that the travel is limited to the
minimum 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 the external epoxy coating.
5.1 Storage
If the valve is not installed immediately after delivery,
it must be put into proper storage.
It should be stored in a dry, vibration-free and well-
ventilated room at as constant a temperature as
possible.
Elastomers are to be protected 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 manufacturer'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 measures
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
regulations.
Neutralise any medium residues in the valve.
Separate valve materials (plastics, metals, etc.)
and dispose of them in accordance with the local
regulations

Series PA/F, PA/S Page 9
9510-060-en Revision 17
TM 9549 Edition 07/2016
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,
especially hard foreign matter.
During installation, pay attention to the correct
tightening torque, aligned pipes and tension-free
assembly.
It must be ensured that the lever swings freely
(dead man'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 are glass-lined, PTFE-lined
gaskets with a metal inlay should be used. These
gaskets are available as special 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
(deviations from this position require a special bottle
connection). See Section 10.4 and 10.9.
6.3 Grounding
The valve must be grounded. The simplest solution is
to use tooth lock washers which are placed under one
pipe bolt of each flange.
Otherwise grounding must be ensured by different
measures e.g. a cable link.
At the customer's request a setscrew M6 with a hex.
nut and washer will be provided at each flange as an
additional grounding connection.
6.4 Test pressure
The test pressure PT of an open valve must not
exceed the value of 1.5 x PS(PN) as per the
identification of the valve.
6.5 Star knop
The stroke and thus the pressure reduction and
medium 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
intensity you want.
Release lever and lock the star knob in this
position.
This procedure guarantees that with each further
sampling 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 ball valves have been tested
for leaks with air or water. Prior to initial
operation check body bolting. For torques
see Section 1.2.
Unless otherwise agreed, there could be residual
amounts of water in the flow section of the ball 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 torques see Section 1.2.
7.2 Improper operation and their
consequences
Crystallisation may result in damage to the seat
rings or ball/stem unit. This can be prevented by
heating, for example.
In extreme cases a leak may occur.
Increased wear occurs when the valve is operated
with solid contents.
Violent opening or rapid filling may cause the bottle
to burst.
Non-observance of the pressure-temperature
diagram may result in 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 addi-
tion, a pin is inserted into the middle hole, it must
be ensured that sampling does not take place
accidentally.

Series PA/F, PA/S Page 11
9510-060-en Revision 17
TM 9549 Edition 07/2016
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 risk-
free 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
dismantling 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. Even if the valve
has been properly emptied and rinsed,
residual medium may still be found in the valve.
After dismantling, immediately protect the valve
flanges against mechanical damage with flange caps.
See also Section 6.1.
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
inspect the ball valve.
Flange connection body/seat or body/cover is
leaking
Retighten body screws. See paragraph "Flange
connection ball valve/pipe is leaking".
Packing leaks
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 knob and close the
valve using the star knob.

Series PA/F, PA/S Page 12

TM 9549 Edition 07/2016
9 Maintenance
All repair work is to be performed by qualified
personnel using the appropriate tools. Generally
recognised practice in mechanical engineering is
to be observed.
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 connec-
tion screws should be made in line with the operat-
ing requirements.
For torques see Section 1.2.
Make sure that when working on the
sampling valve it is drained.
