2 Safety
2.1 Intended use
The mixproof valve R is used for the mix-proof shut-off of high-grade, non-
abrasive products at intersection points in pipe systems.
It is resistant to pressure surges in its closed state.
Hint!
Do not install the valve in spring-opening, as this will open when there
is a current or air failure and leads to product mixing.
In a closed pipe system, hydraulic pressure build-up may occur when the valve
switches and result in seal damage.
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) in the sense
of the pressure equipment directive 2014/68/EU: They are classified according to
Annex II in category 1.
According to the scope of directive 2014/64/EC, article 1, paragraph 2, f, the
exception of the directive applies, due to conformity with the machine directive
2006/42/EU.
The nominal diameters smaller than DN25 are subject to article 4, paragraph 3 of
the Pressure Equipment Directive which specifies sound engineering practice.
Nominal diameters ≥ IPS 4“; DN 125 valid for the fluid group II.
In the event of any deviations, GEA Tuchenhagen GmbH will supply a specific
Declaration of Conformity.
2.1.3 ATEX directive
In areas with an explosive atmosphere, only valves suitable for use in such areas
may be used.
Refer to and observe the additional operating instructions “ATEX version valves”.
For details regarding the marking of valves for potentially hazardous areas also
refer to the additional operating instructions “ATEX version valves”.
Safety
Intended use
430BAL008386EN_3
07.02.2022 9
If these valves are used in areas with a potentially explosive atmosphere, you
must absolutely comply with directive 2014/34/EC with respect to all ignition
hazards.
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.
The operation of the component is not permitted if:
•Persons or objects are in the danger zone.
•Safety devices are not working or were removed.
•Malfunctions have been detected on the component.
•Damage to the component has been detected.
