2 Safety

2.1 Intended use

Aseptic double-chamber valves are mix-proof stroke valves for highly hygienic

and aseptic process systems and permit the safe separation of incompatible

media. The media separation is done via the integrated sterile chamber (ISB),

which is separated hermetically from the atmosphere with a seal each to both

product lines and via two side valves (inlet and outlet).

For safe operation, it is mandatory that the following points are observed in the

different process steps:

Transfer

During a media transfer through the main valve both side valves must be closed

completely.

Fig.1: Product transfer

Cleaning sterile chamber

After a media transfer the sterile chamber must be flushed at least with one

sterile medium. After the main valve has been closed, both side valves can be

put in the open position and thus permit the flushing of the sterile chamber.

Fig.2: Rinsing / sterilisation after transfer

CIP cleaning with seat lift

If seat lifting is activated for a CIP cleaning (preferably in cycles) no process must

be running in the opposite line. Furthermore, the outlet valve of the sterile

chamber to drain the CIP medium must be open.

Safety

Intended use

430BAL013307EN_8

8 04.08.2022

Fig.3: Seat cleaning valve disk Fig.4: Seat cleaning double disk

The medium should preferably flow in the opening direction of the valve disk to

avoid pipe hammers when the valve is opened or closed. Should this not be

possible due to technical reasons related to the plant or process, it is

recommended to switch the valve without pressure. Both measures prevent

pressure hammers when the valve is opened or closed.

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 component is a piece of pressure equipment (without safety function) in the

sense of the pressure equipment directive: Directive 2014/68/EG. They are

classified according to Annex II, article 4, section 3. 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”.

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 reliability of the valve cannot be ensured under improper

operating conditions. Therefore avoid improper operating conditions.

Operating the valve 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 valve.

•Damage has been detected on the valve.

•Maintenance intervals have been exceeded.

•the position of the side valves is not adjusted to the process steps

Hint!

Negative pressure and switching under negative pressure in the

pipeline can lead to damage to the membrane.

2.2 Operator’s Duty of Care

In your capacity as operator of the facility you bear a particular responsibility for

the proper and safe handling of the valve in your facility. Only use the valve when

it is in perfect condition to prevent danger to persons and property.

These Operating Instructions contain the information you and your staff need for

the safe and reliable operation during the entire service life of the valve. Be sure

to read these Operating Instructions carefully and ensure that the measures

described here are observed.

The operator's duty of care includes planning the necessary safety measures and

monitoring that these measures are observed. The following principles apply:

•Only allow qualified staff to work on the valve.

•The operator must authorize the staff to carry out the relevant tasks.

•Working areas and the entire environment of the valve must be neat and

clean.

•The staff must wear suitable work clothing and personal protective equipment.

As the operator of the facility make sure that work clothing and personal

protective equipment are used.

•Instruct the staff with regard to any properties of the product which might pose

a health risk and the preventative measures to be taken.

•Have a qualified first-aider on call during the operation, who can initiate the

necessary first-aid measures in case of an emergency.

•Clearly define processes, lines of authority and responsibilities associated

with the valve. Everybody must know what to do in case of an emergency.

Instruct the staff in this respect at regular intervals.

•The signs relating to the valve must always be complete and legible. Check,

clean and replace the signs as necessary at regular intervals.
