Motorized Linear Actuator
baelz 373-E45
1.7 Motorized linear actuator
The baelz 373-E45 is a motorized linear actuator with load-dependent limit switches for flow
control applications. The actuators are designed for highly accurate positioning in an industrial
environment. They come complete with a manual adjustment device and a wide range of
options and additional extras are available.
Each actuator has a nameplate showing specifications regarding the maximum operating
conditions of the device and a unique, order-related serial number (F no.).
