2 Safety
2.1 Intended use
Aseptic counter pressure valves are stroke valves and are used to control a
predefined pressure in aseptic process systems. The desired product pressure is
achieved by supplying compressed air into the pneumatic actuator. A welded
stainless steel bellows (or PTFE bellows as an option) is used to hermetically
seal the valve disc. 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 counterpressure valve (GD) should close against the direction of flow of the
medium if possible. Should this not be possible due to technical reasons related
to the plant or process, the valve must be depressurized. Both measures prevent
pressure hammers when the valve is switched. Furthermore, counterpressure
valves must be put into a defined end position (open or closed) to protect the
bellow during CIP/SIP processes. The valve is monitored, controlled and
operated by the customer's system.
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 of such misuse lies entirely with
the operator of the facility.
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.

of components from GEA Aseptomag AG. The reference numbers can be used to
clearly identify a component and its composition.
Number
(Example) Designation Description
0001 14 Serial valve
number
The valve serial number is the easiest and most definite
way to identify a component from GEA Aseptomag AG.
This number is unique and allows all components
installed at the time of delivery to be identified. The first
four digits represent a chronological, ascending number,
the last two digits provide information about the year of
manufacture. The valve's serial number is indicated on a
round white sticker affixed to the actuator.
0001 14 Serial number
main components
The serial number has the same structure as the valve's
serial number, but it is placed on the relevant main
component (housing, internal assembly, actuator) by
laser marking / stamping.
V-50-1001 Drawing number The drawing number is a combination of two groups. The
digits in front of the hyphen refer to where the
components belong to. The next four numbers describe
the part in more detail. For this purpose, the main
component groups of a valve are assigned to various
groups:
•V-xx-0xxx = entire valves
•V-xx-1xxx = valve housings
•V-xx-2xxx = internal assemblies
•V-xx-3xxx = actuators
•V-xx-4xxx = feedback units / accessories
Each of these main components is marked and can be uniquely identified.
! Other markings on components of the valve, such as on connectors, arise from
the production process and are not relevant.

4 Transport and storage
4.1 Storage conditions
The valves, valve inserts or spare parts should be stored in a dry place, free of
vibrations and dust, and protected from light. To avoid damage, leave the
components in their original packaging if possible.
If, during transport or storage, the valve is going to be exposed to temperatures ≤
0°C, it must be dried beforehand and suitable measures must be taken to protect
it from damage.
Hint!
We recommend that the valve should be stored at a temperature of ≥ 5
°C for a period of 24 hours prior to any handling (disassembling the
housings / activation of actuators) so that any ice crystals formed by
condensation water can melt.
4.2 Transport
For transport, the following principles apply:
•Only use suitable lifting gear and slings for transporting the package units/
valves.
•Observe the pictograms on the package.
•Handle valves with care to avoid damage caused by impact or careless
loading and unloading. The outside synthetic materials are susceptible to
breaking.
•Control tops (if fitted) must be protected from animal and vegetable fats.
•Only allow qualified staff to transport the valve.
•Movable parts must be properly secured.
•Only use approved, fully functional load lifting devices and lifting accessories
which are suitable for the intended purpose. Observe the maximum load-
bearing capacities.
•Secure the valve against slipping. Take the weight of the valve into account
and the position of the point of gravity.
•Under no circumstances should anyone stand under a suspended load.
•Take care when transporting the valve. Do not grip sensitive parts of the unit
to lift or push the unit or to support yourself. Avoid putting the unit down with a
jerk.
4.2.1 Scope of supply
