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 type 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

Notes:
The next lower kv100/Cv value can also be achieved with special plugs without changing the seat ø.
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.

The valve travel depends on the actuator selected.
XF = Differential pressure ratio
Δp = Differential pressure input/outlet
p1 = Absolute pressure at inlet
pv = Vapour pressure at operating temp.
XF ≤ z : non-critical conditions
XF ≤ 1,4 x z : tolerable cavitation
XF > 1,4 x z : inadmissible cavitation

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 Δp 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
Δp > 10 bar / 145 psi to Seat-Ø 15-50 mm
Δp > 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 control 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
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 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.
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.
