2 Safety Information
A suitable material pairing for the casing, sealing plate and sealing ring is to be selected for the conditions
in which the valve is used. If you have any doubt, please consult JAUDT.
JAUDT vario butterfly valves with levers may cause burn injuries if they are used for substances with a high
processing temperature. In these cases you must wear gloves.
On powered JAUDT vario butterfly valves the drive unit is to be fitted with a suitable guard to ensure that it
cannot cause injury. This guard is to be provided by the system manufacturer.
If necessary the safety officer and/or the environmental officer is to be notified before work is commenced.
JAUDT vario butterfly valves are state of the art. Nevertheless they can cause damage and personal injury
if they are not operated correctly. We warn you about these risks in the form of suitable instructions. These
instructions are highlighted by special symbols.
The directives of the Accident Prevention Regulations are to be followed to the letter
Danger of death!
This symbol alerts you to a danger that constitutes a risk to personnel from electrical power.
Danger of injury!
This symbol alerts you to a danger that constitutes a risk to personnel.
Danger of material damage!
This symbol alerts you about action that may cause damage to the JAUDT bucket wheel
feeder.

This dot prompts you to carry out a specific action.
The order of these actions must be followed to the letter.
2.1 Areas of Use
JAUDT Vario Butterfly valves are suitable for free-flowing powdery to fine-grained bulk goods of all kinds,
including products of the food industry. For other applications, in particular gases and liquids, we would be
happy to offer specialist advice.
They are not suitable for aluminium and decomposing media.
The quality of the sealing ring and the sealing plate should be chosen in accordance with the purpose of use
and the medium to be transported (temperature, aggressive properties, etc.).

3 Operation and Installation
3.1 Operation
JAUDT Vario butterfly valves can be supplied as desired with the following methods of operation:
Hand-operated lever
Pneumatic cylinder
Pneumatic rotating actuator (PDA)
Electric servo drive
Special equipment hydraulic cylinder
Attention: Limit the activation pressure on 40 bar, in order to avoid damages of the equipment
on blocking the sealing plate.
No particular instructions need to be observed for operation. The position of the flap is indicared by the
notch on the end of the shaft.
Models with the hand-operated lever are provided with additional markings at 15°-intervals:

3.2 Installation
3.2.1 Installed Position
Depending on the desired method of operation, the following must be taken into account when installing
JAUDT Vario butterfly valves:
Hand-operated lever: any desired position
Motor drive: position housing horizontally (see Fig. on Page 5)
Other positions on request.
Pneumatic drive: any desired position
3.2.2 Installation Instructions
The installation of JAUDT Vario butterfly valves can be carried out by skilled workmen without the need for
special tools or fixtures. Before installation, check the following:
The opposing flange surfaces must be parallel.
The internal diameter of the opposing flange must correspond to the internal diameter of the butterfly
valve. The sealing plate must be able to turn over the whole 90° range of rotation without obstruction.
Are the materials for the sealing plate/seals suitable for the usage envisaged?
All flange surfaces must be clean.
Always install with the sealing plate in the closed position.
Align the JAUDT Vario butterfly valve precisely with the pipework.
No tension should be put on the JAUDT Vario butterfly valve during installation. Therefore tighten the
fittings crosswise over the valve.
The maximal torque of 60 Nm with surface mounting (1 adapter) and of 100 Nm with intermediate
flange (2 adapter) may not be exceeded.
Only for JAUDT Vario butterfly valves with a continuous seal:
An additional flange seal is not necessary. The protruding seal-ring on the rotary flap ensures leak-
tightness when the opposing flange is surface parallel.

4 Inspection and Maintenance
The following information refers to DIN 31051 "Terminology and action for maintenance".
4.1 Inspection and Adjustments
The following inspections are to be carried out every 6 months:
Danger of injury!
Before completing any maintenance work, switch off the power supply (electrical and
pneumatic) to powered JAUDT butterfly valves and inform the control room if necessary.
a) Visual check of condition, leak-tightness and cleanliness
b) Check tightness of screws and fitments
c) Operation of the JAUDT Vario butterfly valve
with hand-lever; check for ease of movement
with drive; check for noise and ease of movement
d) Check connections (electrical und pneumatic)
e) With pneumatic rotating actuator (PDA) and cylinder
check functioning of solenoid valve
f) Check pneumatic supply, remove water if necessary (user)
g) With electric servo drive (Deufra)
check electrical connections
check for leak-tightness and oxidation
check tightness of PG screw fasteners and plastic plugs
h) By JAUDT Vario butterfly valves with pneumatic-cylinder, check angular adjustment
Loosen lock-nut of the ball at the end of the pneumatic cylinders
Adjust zero-point of the sealing plate by turning the piston rod of the cylinder
Tighten lock-nut of the ball
i) By JAUDT Vario butterfly valves with pneumatic rotating actuator (PDA):
The PDA has a turning angle of 90 3 and is set to 90 0 at the factory. This ensures perfect closure
of the sealing plate.
Loosen lock-nuts on both sides of the PDA and turn the socket-head screw until the sealing plate
closes in an optimum manner
Tighten lock-nuts
NOTE: This adjustment must be carried out on both sides of the PRD.
j) Check limit switch
Check limit switch condition and functioning. Check tightness of accident prevention guard.

4.2 Maintenance Work
Maintenance work should be carried out at 2-yearly intervals. JAUDT Vario butterfly valves in continuous
use or being used in extremely critical areas should be serviced annually.
The maintenance work always includes the above-mentioned inspections.
Danger of injury!
If the valve is used to meter hot substances of substances that are intolerant to the skin:
Protect yourself with safety clothing, goggles and breathing apparatus.
Notify the safety and environmental officer.
Keep a collection vessel available.
If the sealing plate is difficult to move or the rotary flap is not leak-proof
remove and dismantle JAUDT Vario butterfly valve
check bearing and replace if necessary
check sealing ring and replace if necessary
