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!
Installation and operation are to be performed by
qualified staff.
For valves which are used in potentially explosive
areas, see Section 3.
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 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 check valves are pressure relief components
in accordance with the Pressure Equipment Directive
(PED) for the passage of fluids in the direction of the
flow arrow on the body and for the shut-off of fluids in
the opposite direction.
However, shut-off of the passage of fluids in the
opposite direction may be cancelled out, depending
on the installation position, ball design, differential
pressure and medium.
The valves are suitable for vapours, gases and liquids
of group 1 in accordance with the PED and have a
corrosion-resistant plastic lining.
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 examine whether the design of the valve,
accessories and materials are suitable for the new
application (consult the manufacturer). Please consult
the manufacturer.
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
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 safety 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.
