VAG Installation and Operation Instructions
Any deviating operating conditions and applications require the
manufacturer‘s prior written consent!
These Installation and Operation Instructions contain important
information on the safe and reliable operation of the VAG ROTOP®.
Observing these Operation and Maintenance Instructions helps
you to:
•Prevent hazards
•Reduce repair costs and down-times of the drive and/or the
complete system
•Improve the operational safety and useful life of the equipment
2 Transport and Storage
2.1 Transport
The VAG ROTOP®should be transported in such a way that it is
protected from external influences such as cold and damp, soiling
and mechanical influences. The carrying case available from the
accessories programme reliably protects the drive.
2.2 Storage
The VAG ROTOP®should be stored in such a way that sufficient
protection against damage from improper storage is ensured. Fur-
thermore, the VAG ROTOP®should be stored in such a way that
avoids condensation forming in the machine. The VAG ROTOP®
may not be subjected to great heat for an extended period of time.
The fitting can be stored in ambient temperatures ranging from -20
°C to + 50 °C (protected by adequate covers).
3 Product features
3.1 Features and function description
The VAG ROTOP®is a portable electric drive for the easy and er-
gonomic operation of valves with and without housing. The high-
torque drive with up to 230 Nm enables the comfortable operation
of gate valves, butterfly valves and underground hydrants. The
application options offered by the different coupling sleeves make
the VAG ROTOP®compatible with any valve. An integrated torque
control prevents unintentional damage to the valves.
The VAG ROTOP®is available in a version with infinitely variable
speed or in a version with two pre-adjusted speeds.
3.2 Fields of application
The standard version of the VAG ROTOP®is suitable for all valve
types via the use of different coupling sleeves.
For technical data concerning temperature operating limits please
refer to document KAT-A 5551.
Contact the manufacturer in the event of divergent operating con-
ditions and areas of application.
3.3 Performance limits
Overload protection is triggered should the VAG ROTOP®become
overloaded. The trigger point of overload protection depends on
the period of operation and the specified torque.
The overload protector is located next to the motor on the right.
A safety pin integrated into the overload protector pops out and
the VAG ROTOP®can no longer be operated. Only after a cooling

1.1 Safety
These Operation and Maintenance Instructions must
be observed and applied at all times along with the ge-
neral „VAG Installation and Operation Instructions for
Valves“ (see www.vag-group.com / Category: Installa-
tion and Operation Instructions).
Arbitrary alterations of this product and of the parts and acces-
sories supplied with it are not allowed. VAG does not assume any
warranty or liability for consequential damage arising from non-
compliance with these instructions. When using this drive, the
generally acknowledged rules of technology have to be observed
(e.g. DIN standards, DVGW data sheets, VDI directives, etc.). The
installation may only be carried out by qualified staff (see also
Section 7.1 General safety instructions). For further technical in-
formation such as dimensions, materials or applications, please
refer to the respective documentation (KAT-A 5551).
The VAG ROTOP®is designed and manufactured to the state of
the art and its safety of operation is ensured in general. However,
the VAG ROTOP®may be potentially dangerous if it is operated
improperly or is not applied for the intended use.
Everyone dealing with the assembly, disassembly, operation,
maintenance and repair of the valves must have read and under-
stood the complete Operating and Maintenance Instructions (Ac-
cident Prevention Regulations, VBG 1 §14 ff and following).
The operator must have a strong foothold when operating the val-
ve with the VAG ROTOP®.
When using the VAG ROTOP®great care must be taken that the
end positions of the valve are approached slowly. Make sure to
watch the display. Any sudden stop would otherwise threaten to
turn the drive as well.
Make sure to observe when in operation:
•For reasons of safety only adjust the torque and direction of
rotation switch when shut down.
•To prolong the service life of the valve and the drive, always
operate at the lowest possible torque.
•To avoid overloads to the valve and the drive, moving to end
position must not be dependent on the torque, but the path,
while watching the counter.
•Even with power switched off the drive will continue to turn until
operating power has been completely dissipated.
•Use the supplied actuator column to give the operator a firm
foothold, especially for stiff valves.
For equipment for which monitoring is mandatory, the relevant
laws and regulations such as the Industrial Code, Accident Pre-
vention Regulations, VDE Guidelines, AD Data Sheets (AD = Boiler
Study Group), etc. must be complied with. In addition to this, local
accident prevention regulations must be complied with.
1.2 Proper use
The VAG ROTOP®is a portable electric drive.
It is suitable for easily and ergonomically operating valves.
For technical data concerning the operating limits such as medi-
um or temperature, please refer to document KAT 5551-A.
