General

Sauter ADM 322: Rotary actuator for best operating convenience, precision activation and high energy efficiency with minimal operating noise.

This actuator is used to operate control units like control valves, butterfly valves etc. in HVAC installations and must only be used for these purposes. The actuator can be used as a 2-point (OPEN/CLOSE) or 3-point actuator (OPEN/STOP/CLOSE). The running time of the actuator can be set with the S1 switches according to the respective requirements.

Features

• For operating control units such as control valves, butterfly valves etc.
• For controllers with a switching output (2-point or 3-point control)
• 15 Nm nominal torque and holding torque
• Synchronous motor with electronic control unit and load-dependent cut-off
• Low operating noise
• Direction of operation and running time can be set using coding switches
• Gear unit can be disengaged for manual adjustment
• Electrical parallel operation of up to five actuators possible
• Numerous adapters enable the unit to be fitted onto defined non-SAUTER control valves
• Maintenance-free gearbox made of plastic and steel, and gearbox base-plates made of steel
• Mounting columns made of aluminium
