2.1 Intended use
Richter sampling valves are pressure-maintaining com-
ponents in accordance with the Pressure Equipment
Directive (DGRL) for taking liquid samples.
The standard PA/F and PA/S are only intended for hor-
izontal installation (vertical installation only with special
adapter).
The valves are suitable for non-boiling liquids of group
1 in acc. with the Pressure Equipment Directive
(DGRL).
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 ex-
amine whether the design of the valve, accessories and
materials are suitable for the new application. (Please
