2.1 Intended use
The control valve is used for the regulation of media in the food and beverage industry, in pharma-
ceutical and chemical engineering, as well as in bio-engineering.
2.2 General notes
NOTICE - observe the operating instructions
To avoid danger and damage, the fitting must be used in accordance with the safety instructions
and technical data contained in the operating instructions.
NOTICE
All data are in line with the current state of development. Subject to change as a result of tech-
nical progress.
2.3 General safety instructions
WARNING
Risk of injury by moving parts
Do not grab into the valve when the actuator is pressurized. Limbs can be crushing or amputating.
– Remove the control air line before dismantling.
– Ensure that the actuator is unpressurized.
WARNING
Risk of injury by outflowing medium
Dismantling the valve or valve assemblies from the plant can cause injuries.
– Medias flowing through the leakage drain outlet are to be drained off without splashing
into a discharge arrangement.
– Carry the disassembling only if when the plant has been rendered pressure-less and free
of liquid and gas.
WARNING
Risk of injury by moving parts
When dismount the clamp coupling, the spring preloaded valve insert (air open - spring close) may
incur serious injuries by jumping out of the housing.
– First pneumatically open the valve before disassembling the clamp coupling, so that up-
stroke the piston.
– Remove the valve core.
– Remove the control air line at valve insert.
ðEnsure that the actuator is unpressurized.
WARNING
ATEX - Guidelines
If the valve or the plant is operated in a potentially explosive atmosphere, the valid ATEX directive of
the EC and the installation instructions in this operating manual must be observed.

KIESELMANN GmbH | Operating Instructions Safety instructions | 2
91xx_RV_EN 7 / 42
CAUTION
When mounting the clamps, the max. torque must not be exceeded.
(see technical data)
CAUTION
To avoid air leaking, only use pneumatic connection parts that have an O-ring seal facing the even
surface.
CAUTION
Before starting the system, the entire pipeline system must be thoroughly cleaned.
CAUTION
Steps should be taken to ensure that no external forces are exerted on the fitting.

avoid a prolonged storage
INFORMATION
Recommendation for longer storage
We recommend regularly checking the product and the prevailing storage conditions during long
storage times.
• To avoid damage to seals and bearings,
– products up to DN 125 / OD 5 inch should be stored horizontally for maximum 6 months.
– products larger than DN 125 / 5 inch, should be stored in the upright position with the actu-
ator on top.
• Don't store any objects on the products.
• Protect the products for wetness, dust and dirt.
• The product should be stored in a dry and well ventilated room at a constant temperature (op-
timal indoor temperature: 25 C ±5; indoor humidity data 70% ±5%).
• Protect seals, bearings and plastic parts for UV light and ozone.

5 Function and operation
5.1 Description of function
The control valve is based on the KIESELMANN AI DS technology. Media with a KVS -values 0,1 m³/
h to 160 m³/h can be regulated through the interchangeable seat concept.
Control via Bürkert Positioner
The valve is operated by means of a digital electro-pneumatic positioner. The positioner forms a
closed circuit loop together with the lift actuator and the valve. The lift position defines the actual
value which is recorded by a potentiometer. A proportional position is controlled with the specified
target value (4-20mA). During the regulating process, the target value is constantly compared to the
actual value; any regulating deviations are corrected. The micro-controller regulator allows an auto-
matic zero and lift alignment and automatic commissioning.
Description of function - Control valve
Valve function: • Regulation of media in pipelines.
Operation: • pneumatic operation by a lift drive (air/spring or air/air)
• manual operation by a crank-handle (open ↺ / close ↻)
Activation: • pneumatically via solenoid valves (positioner)
(see "Control via Bürkert positioner")
Description of function - Lift actuator

6 Commissioning, service and maintenance
6.1 Commissioning
NOTICE
Check the valve for function!
Before using the valve, the function of the valve must be checked.
– Open and close the valve manually via the positioner.
– Check the settings of the positioner.
ð(Please refer the operating instructions of the positioner).
6.1.1 Installation instructions
Fitting position
Any installation position is possible, however preferably it should be installed vertic-
ally. Non-vertical installation means that the outflow pipes must be arranged to al-
low the liquids to run freely out of the housing.
NOTICE
The flow direction is generally in the direction A.
If installed horizontally, some minor residual liquids will remain in the housing.
6.1.2 General welding guidelines
Sealing elements integrated in weld components must generally be removed prior to welding. To
prevent damage, welding should be undertaken by certified personnel (EN ISO 9606-1). Use the TIG
(Tungsten Inert Gas) welding process.
CAUTION
Damage and injuries due to high temperature supply
To avoid a distortion of the components, all welding parts must be welded to stress-relieved.
Allow all components to cool before assembling.
NOTICE
Damage due to impurities
Impurities can cause damage to the seals and seals area.
Clean inside areas prior to assembly.
6.1.3 ATEX - Guidelines
For valves or plants/installations that are operated in the ATEX area, sufficient bonding (grounding)
must be ensured (see valid ATEX Guidelines EG).

6.2 Service
RECOMMENDATION
Replacement of seals
To achieve optimal maintenance cycles, the following points must be observed!
– When replacement of seals, all product-contacting seals should be replaced.
– Only original spare parts may be installed.
Maintenance interval
The maintenance intervals depend on the operating conditions "temperature, temperature-intervals,
medium, cleaning medium, pressure and opening frequency". We recommend replacing the seals1-
year cycle. The user, however should establish appropriate maintenance intervals according to the
condition of the seals.
Lubricant recommendation
EPDM; HNBR; NBR; FKM; k-flex - Klüber Paraliq GTE703*
Silicone - Klüber Sintheso pro AA2*
Thread - Interflon Food*
*) It is only permitted to use approved lubricants, if the respective fitting is used for the produc-
tion of food or drink. Please observe the relevant safety data sheets of the manufacturers of lub-
ricants.
6.3 Cleaning
Cleaning
Ideally, cleaning is carried out with pipe system cleaning when the valve is open.
