2 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 overflow 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 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 overflow valves of the GUT series are
pressure-maintaining components in accordance with
the Pressure Equipment Directive (DGRL) for the
passage of fluids at a given test pressure.
The valves are suitable for non-boiling liquids of group
1 in acc. with the Pressure Equipment Directive
(DGRL).
They 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.
The overflow valves are set at the works to the
desired set pressure, tested and lead-sealed.
Exact operating conditions of the overflow valve
selected are documented in the
data sheet . There
you will find the performance characteristics such as
the certified coefficient of discharge, flow area, set
pressure, opening pressure, reseating pressure and
materials.
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. (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 operating conditions stipulated in the data
sheet are not exceeded in continuous operating
mode.
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 name plate and
in the pressure-temperature diagram must under no
circumstances be exceeded.
See also improper operation and their consequences
in
Section 7.4 .
