and VBI61..) or externally threaded connections (VAG61.. and VBG61..),

DN15 to DN25

● For 6-port control ball valves VWG41.. with externally threaded connections,

DN10 to DN20

● Nominal torque 5 Nm

● Operating voltage AC 24 V ~ / DC 24…48 V ⎓ or AC 100…240 V ~

● Positioning signal DC 0/2…10 V ⎓

● Pre-wired with 0.9 m long connection cables

Features ● Brushless, robust DC motors ensure reliable operation regardless of load. ● The rotary actuators do not require an end position switch, are overload proof, and remain in place upon reaching the end stop. ● The gears are maintenance free and low noise. ● Suitable for use with modulating controllers (DC 0/2...10 V), open-close or three-position controllers. ● We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3point control to ensure continuous and accurate operation.

Position indication: Electrical Output voltage U = DC 0/2...10 V is generated proportional to the rotary angle. U depends on the rotary direction of the DIL switch setting. Self-adaptation of linear span When self-adaptation is active, the actuator automatically determines the mechanical end positions of the linear span. Manual adjustment The rotary actuator can be manually adjusted by pressing the gear train disengagement button.
