Safety notes
!
• The actuator has been designed for use in stationary heating, ventilation and air conditioning
systems and is not allowed to be used outside the specified field of application, especially in
aircraft or in any other airborne means of transport.
• It may only be installed by suitably trained personnel.
All applicable legal or institutional installation regulations must be complied with.
• The device may only be opened at the manufacturer's site. It does not contain any parts that
can be replaced or repaired by the user.
• The cable must not be removed from the device.
• The device contains electrical and electronic components and is not allowed to be disposed
of as household refuse. All locally valid regulations and requirements must be observed.
Product features
Mode of operation
Simple direct mounting
Manual override
Adjustable angle of rotation
High operational reliability
Combination valve actuators
The actuator moves the ball valve to the operating position at the same time as tensioning the
return spring. The ball valve is turned back to the safety position by spring force if the supply
voltage is interrupted.
Straightforward direct mounting on the ball valve with only one screw. The mounting position in
relation to the ball valve can be selected in 90° steps.
Manual operation of the valve with the hand crank, locking in any position with the interlocking
switch. Unlocking is manual or automatic by applying the operating voltage.
Adjustable angle of rotation with mechanical end stop.
The actuator is overload-proof, requires no limit switches and automatically stops when the end
stop is reached.
Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.

Notes
!
• Connect via safety isolation transformer.
• Parallel connection of other actuators possible.

Flexible signalization
The actuator has one auxiliary switch with a fixed setting and one adjustable auxiliary switch.
They permit a 10% or 11 ... 100% angle of rotation to be signalled.
Combination valve actuators
Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.
