BB models (5.6 Nm torque)
This compact quarter turn actuator may be directly coupled to either a 16 mm round or 10 mm square jack shaft or remotely mounted using an adaptor kit.
All motors are bi-directional under power and, in the case of models equipped with the Enerdrive System,
under failsafe conditions. The stroke may be limited to less than 90° mechanically. This model is available with or without the Enerdrive, failsafe system.
The BB models are available with programable, multi signal, analogue or on/off floating control.
Applications
Small dampers
Unit ventilators
1/4 turn valves
VAV box control
Fan coils
