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 diaphragm valves are pressure containing
components in accordance with the Pressure
Equipment Directive (PED) for the passage and shut-
off of fluids at a specified differential pressure.
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.
They are used as shut-off, control and throttling
valves for corrosive, pure and high-purity liquids,
gases and vapours in chemical, pharmaceutical, food
and industrial processes.
They are hermetically tight.
The wetted materials are FDA-compliant.
Richter diaphragm valves are soft-sealing and gas-
tight.
Solids can lead to increased wear, leaks, damage to
sealing surfaces or to a reduction in the service life of
the valve.
If the valve is intended for operating data other than
those intended, the customer must carefully examine
whether the design of the valve, accessories and
materials are suitable for the new application (consult
the manufacturer).
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.
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).
Diaphragm valves which are used as end
valves must be sealed with a blind flange at
the free connection end and appropriately
secured against unauthorised activation.
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.
