In connection with the basic unit (e.g. LMV5...): Via the display and operating unit
AZL5… (refer to Basic Documentation P7550).
RAST3.5 terminals (supplied together with the AGG5.720 / AGG5.721).
SQM45...: Spur gears made of plastic with small backlash and permanent lubrication.
SQM48...: Spur gears made of steel with small backlash and permanent lubrication.
Made of black-finished steel, ready fitted to the front of the gear train (SQM48... uses a
drive shaft made of hardened steel).
The front of the gear train is used as the mounting surface. The actuator has 4 fixing
holes and 1 elongated hole for the positioning pin.
Alternatively, the actuator can be secured from the side of the controlling element with
3 self-tapping screws.
For mounting of SQM45.295x9 actuator on VKF41.xxC butterfly valve, an ASK33.4
mounting kit is always required.
The mounting kit consists of coupling with a preassembled mounting kit.
