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.
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 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 hazard-
ous substances.
2.1 Intended use
Richter check valves of the series GR/F are pressure-
maintaining items of equipment in accordance with the
German Pressure Equipment Directive (DGRL) for the
passage of fluids in the direction of the flow arrow
provided on the body and for blocking the passage in
the opposite direction.
The GR/F is intended for horizontal installation.
The valves are suitable for vapours, gases and liquids
of group 1 in accordance with the PED and have a
corrosion-resistant plastic lining.
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 manufac-
turer).
2.2 For the customer / operator
When using the valve, it must be ensured 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 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 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.
