2.1 Intended use
Richter sight glasses of the series PSG/F and TSG/F
are pressure-maintaining components in accordance
with the Pressure Equipment Directive (PED) for the
passage of fluids.
They permit a view into the housing interior from two
opposite sides.
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 sight glasses serves to the monitoring of flow,
filling level, condition, colour and gas contents of
media in pipes and vessels and near pumps.
The operator must carefully check in the event of
operating data other than those provided whether the
designs of the strainer, accessories and materials are
suitable for the new application (consultation with the
manufacturer).
2.2 For the customer / operator
When using the valve, 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 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.
3 Safety notes for applications in potentially explosive areas
based on the Directive 94/9/ EC (ATEX 95)
The valves are intended for use in a potentially
explosive area and are therefore subject to the
conformity assessment procedure of the directive
94/9/EC (ATEX).
As part of this conformity assessment, an ignition
hazard analysis to EN 13463-1 to satisfy the
fundamental safety and health requirements was
conducted with the following result:
The valves do not have any ignition source of
their own.
The valves are not covered by the scope of
application of the ATEX directive and therefore
do not need to be identified accordingly.
The valves may be used in a potentially
explosive area.
It is imperative to observe the individual points of
intended use for application in a potentially explosive
area.
3.1 Intended use
Improper operation, even for brief periods, may
result in serious damage to the valve.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and
induced charges, mechanical and electric sparks)
may result from these Improper operation; their
occurrence can only be prevented by adhering to
the intended use.
Furthermore, reference is made in this connection to
the Directive 95/C332/06 (ATEX 118a) which contains
the minimum regulations for improving the
occupational health and safety of the workers who
may be at risk from an explosive atmosphere.
A difference is made between two cases for the use of
chargeable liquids (conductivity < 10
-8 S/m):
