1.1 Name plate, CE and body markings
The stainless steel name plate is undetachably riveted to
the body.
If the operator attaches his identification, it must be
ensured that the valve matches the application in
question.
Example of name plate with CE marking:
No CE marking is permissible for the sizes 15, 20 and 25;
the name plate therefore has no CE marking.
Example: Name plate for control data
If heavy-duty bellows are installed, another name plate
indicates this:
HD - BVA = Heavy-duty bellows with support rings of
stainless steel
HD - BKo = Heavy-duty bellows with support rings of
PTFE/carbon
Body identification:
The following are visible on the body according to DIN EN
19 and AD 2000 A4:
 Nominal size
 Rated pressure
 Body material
 Manufacturer's identification
 Melt number/Foundry identification
 Cast date
 Arrow for direction of flow

According to AD 2000
According to ASME B 16.42
When used in the area of application of ASME or
ANSI/ISA, the low temperature of ASTM A395 is limited to
-20°F (-29°C).
When used in the minus temperature range, the
regulations applicable in the country in question
must be observed.

Notes:
The next lower kv100/Cv value can also be achieved with special plugs without changing the seat .
This is important if the kv100/Cv value is subsequently changed as only the plug then has to be replaced.
Conversion into Cv (US gpm) = kv100 x 1,165.

1.8 Opening and closing forces required
The values specified in the tables apply to a seat/plug
material of modified PTFE.
With other materials, e.g. PTFE/carbon, higher closing
forces are required. Please inquire at manufacturer's.
If the maximum p is < p2, p2 is used in the tables.
observe the application limits acc. to the pressure-
temperature diagram in Section 1.4.
 A mechanical travel stop is required in the area
marked.
It is provided when
p > 10bar/145 psi to Seat-Ø 15-50 mm
p >6 bar/87 psi to Seat-Ø 65 mm

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 areas,
see Section 3.
Installation and operation 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 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 following
hazards as:
 Failure of important functions of the valve/plant.
 Risk to people from electric, mechanical and chemical
effects.
 Risk to the environment through leaks of hazardous
substances.
2.1 Intended use
Richter bellows-sealed globe control valves of the series
RSS/F are pressure containing components in accordance
with the Pressure Equipment Directive (PED) for the
passage and shut-off of fluids. The valves are suitable for
vapours, gases and non-boiling liquids of group 1
according to the PED and have a corrosion-resistant
plastic lining.
Sie werden zur Regelung von korrosiven, reinen und
hochreinen Flüssigkeiten, Gasen und Dämpfen in Chemie-,
Pharma-, Lebensmittel- und industriellen Prozessen
eingesetzt.
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).
2.2 For the customer / operator
When using the valve, it must be ensured that
 actuators which are retrofitted are adapted and
designed 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 continuous
operation.
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 identifica-
tion plate and in the pressure-temperature
diagram must under no circumstances be
exceeded.
