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 s�ecified field of a��lication, es�ecially in aircraft or in any other airborne means of trans�ort.
• Caution�� Power su��ly voltage!• It may only be installed by suitably trained �ersonnel.
All a��licable legal or institutional installation regulations must be com�lied with.• The device may only be o�ened at the manufacturer's site. It does not contain any �arts that
can be re�laced or re�aired by the user.• The cable must not be removed from the device.• The device contains electrical and electronic com�onents and is not allowed to be dis�osed
of as household refuse. All locally valid regulations and re�uirements must be observed.

Product features
Mode of o�eration 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.
Sim�le direct mounting 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 override 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 Adjustable angle of rotation with mechanical end stop.
High o�erational reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
Combination valve actuators Refer to the valve documentation for suitable valves, their permitted media temperatures and closing pressures.
Notes• Caution: Power supply voltage!• Parallel connection of other actuators possible.
Note the performance data.
