Direct Coupled Actuators are designed
to be used in both damper and valve control
applications. The following general instructions are for
damper applications, refer to the Applicable Literature
table for valve literature.
The MS40-717X series actuators are over the shaft
spring return actuators compatible with 2 to 10 Vdc or
4 to 20 mAdc
