Intended use
WARNING!

General hazard information
Unauthorised use of the device may be hazardous to persons, systems in the vicinity andthe environment.
To use the device, observe the authorized data, operating instructions and application
areas specified in the contract documents and in the operating instructions!
The aseptic multiway valve system Type 2034, referred to below as multiway valve
only,• Is designed for use with ultra-pure, sterile, aggressive or abrasive media which will not
attack the housing or the seal material.
Observe the maximum pressure range on the type label!
• May be used only in conjunction with third-party devices and components recommended
or approved by Bürkert.
• May be used only as intended.
• Prerequisites for safe and trouble-free operation are correct transportation, correct
storage and installation as well as careful operation and maintenance.
• Protect device from harmful environmental influences (radiation, air humidity, fumesetc.). Clarify any ambiguities with the relevant sales office.

Restrictions
NOTE!

Note on property damage:The exhaust air may be contaminated by lubricants in the actuator.
If exporting the system/device, observe any existing restrictions (if applicable).
Explosion protection approval
The explosion protection approval is only valid if you use the modules and components
authorised by Bürkert as described in these operating instructions.
The electronic modules may be used only in combination with the pneumatic valve types
released by Bürkert, otherwise the explosion protection approval will expire!
In the event of unauthorised changes to the system, modules or components, the explosion
protection approval will also expire.

3

Basic safety instructions

These safety instructions do not make allowance for any• eventualities and events which may occur during installation, operation and maintenanceof the devices.
• local safety regulations – the operator is responsible for observing these regulations,also in relation to the installation personnel.

DANGER!
Danger from high pressure!
Before loosening lines and valves, turn off the pressure and vent the lines!
Danger due to electric voltage!
Before reaching into the device or the system, switch off the power supply (if on) andsecure it against reactivation!
Observe applicable accident prevention and safety regulations for electrical equipment!
Risk of burns/fire due to hot device surface if device operated continuously!
Keep the device away from highly flammable substances and media and do not touchwith bare hands!
General hazardous situations!
To prevent injuries, ensure that:- the system cannot be activated unintentionally.
- installation and maintenance work is carried out by authorised technicians only andwith the appropriate tools.
- the process is restarted in a defined or controlled manner after an interruption in the
power supply or pneumatic supply.
- the device is operated only when in perfect working order and in consideration of theoperating instructions.
- the general rules of technology apply to application planning and operation of thedevice.

WARNING!
Danger due to loud noises.
Depending on the operating conditions, the device may generate loud noises. Detailed
information on the likelihood of loud noises is available from the relevant sales office.
→ Wear hearing protection when in the vicinity of the device.

-6-Basic safety instructions

CAUTION!
Medium will escape if the diaphragm is worn
→ Regularly check relief bore for escaping medium.
→ If medium is escaping from the relief bore, change the diaphragm(see chapter Maintenance work).
→ If media is hazardous, protect the area around the discharge point from hazards

NOTE!

Electrostatic sensitive components / modules
The device may contain electronic components which react sensitively to electrostatic
discharge (ESD). Contact with electrostatically charged persons or objects is hazardous
to these components. In the worst case scenario, they will be destroyed immediately or
will fail after start-up
Observe the requirements in accordance with EN 61340-5-1 to minimise or avoid thepossibility of damage caused by a sudden electrostatic discharge!
Ensure that you do not touch the electronic components when the power supply voltage
is applied!
The device was developed with due consideration given to the accepted safety
rules and is state-of-the-art. Nevertheless, dangerous situations may occur.
Operate the device only when it is in perfect condition and in accordance with theoperating instructions.
Non-observance of these instructions and unauthorised tampering with the device
will release us from any liability and also invalidate the warranty covering theaccessories!
• The medium connections of the system may only be fed with media which have been
approved as flow media in chapter 5.1 .
• Do not place the housing under mechanical stress (e.g. by placing objects on it or
standing on it).
• Do not make any external alterations to the device housings. Do not paint housing partsor screws!
• The actuator housing must not be opened. If opened, there is a risk of injury due to thetensioned spring inside.
• Observe the plant-specific safety regulations for application planning and operation.
• If required, transport, install and remove heavy device only with the help of a second
person, using suitable tools.

like and, if required, other components mounted directly on the housing (unless thefactory has already removed them before delivery).
→ Make welded connections according to the designated installation position (in doing so,
observe drainage direction). The preferred installation position can be found in the
supplied dimensional drawing.
→ Provide suitable support according to the weight (see dimensional drawing) of themultiway valve.
→ Assembly of the components. Ensure components are in the correct position (see also
dimensional drawing and the labels which were affixed beforehand).
→ Make pneumatic and electrical connections (if available).
→ Following assembly, the multiway valve is ready for operation.

7.4.2

Housing without welded connections

Procedure:
For information on installation/removal see operating instructions of the types andcomponents used (compare section 5.3), as well as the associated dimensional
drawing.
→ Connect valve body to the pipeline system via the specified connections using therequired components.
→ Make connections according to the designated installation position (in doing so, observedrainage direction). The preferred installation position can be found in the supplieddimensional drawing.
→ Ensure that the multiway valve is suitably supported.
→ Make pneumatic and electrical connections (if available).
→ Following assembly, the multiway valve is ready for operation.
