2 Safety
2.1 Intended use
Inverted aseptic control valves of the type RVIN are stroke valves and are used
for the precise adjustment of parameters such as flow rate, temperature or filling
level in aseptic process plants. With the aid of an electro-pneumatic positioner,
an RVIN inverted control valve ensures the exact positioning of the throttle body
with a pneumatic actuator. A welded metal bellows hermetically seals the valve
spindle. Selected sealing materials in the product chamber ensure optimum
tightness. The valve offers a high degree of process reliability and product quality
in aseptic working processes.
Pressure hammers and excessive control air pressures can destroy the bellows.
The control air pressure should therefore not exceed 8 bar and pressure
hammers in the system should be avoided.
The inverted control valve RVIN reaches its full functionality when it closes
against the flow direction of the medium. Operation with the flow direction is not
recommended. The valve is monitored, controlled and operated by the
customer's installation.
Hint!
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 is borne solely by the operating
company.
2.1.1 Requirements for operation
The prerequisite for reliable and safe operation of the component is proper
transportation and storage as well as professional installation and assembly.
Operating the unit within the limits of its designated use also involves adhering to
the operating, inspection and maintenance instructions.
2.1.2 Pressure equipment directive
The valve is a piece of pressure equipment (without safety function) as defined in
the Pressure Equipment Directive: Directive 2014/68/EG. It is classified according
to Annex II, article 4, section 3. In the event of any deviations, GEA Aseptomag
AG will supply a specific Declaration of Conformity.
2.1.3 ATEX directive
Aseptomag
®
valve technology can also be used in ATEX protected areas.
However, the suitability of the component must be checked under consideration
of the respective conditions. Additional information will be made available upon
request.
2.1.4 Improper operating conditions
The operational safety of the component can not be guaranteed under improper
operating conditions. Therefore avoid improper operating conditions.
