Designated Use
The modulating control valve is used to control flow rates and pressures in automated
process plants.
NOTE
The manufacturer will not accept any liability for damage resulting from any use of the
valve which is not in accordance with the designated use of the valve. The risk of such
misuse lies entirely with the operator of the facility.
Requirements for the Operation
The prerequisite for the reliable and safe operation of the valve is proper transportation
and storage as well as professional installation and assembly. Operating the valve within
the limits of its designated use also involves adhering to the operating, inspection and
maintenance instructions.
Pressure Equipment Directive
The control valves are pressure equipment (without safety function) in the sense of the
pressure equipment directive 97/23/EC. They are classified according to Annex II, article
3, section 3. In the event of any deviations, GEA Tuchenhagen GmbH will supply a
special Declaration of Conformity.
ATEX Directive

absolutely comply with directive 94/9/EC with respect to all ignition hazards.
The supplementary ATEX operating instructions for VARIVENT valves must be
observed. For details regarding the marking of valves for potentially explosive areas also

If used in explosion-proof areas, the regulations laid down in the European standards
DIN EN 60079-0 and DIN EN 60079-11 must be observed.
