1.7 Motorized rotary actuator
The baelz 373-E42 is a motorized rotary actuator for flow control applications requiring a 90°
rotation, such as those using drive butterfly valves or ball valves. The actuators are designed
for highly accurate positioning in an industrial environment. Manual adjustment can be carried
one-handed and without use of a clutch. The travel-dependent and/or torque-dependent limit
switches can be individually configured.
