Application

TAC DuraDrive  Direct Coupled Actuators are designed 
to be used in both damper and valve control 
applications. The follow general instructions are for 
damper applications, refer to the Applicable Literature 
table for valve literature.

The MA40-717X series actuators are over the shaft 
spring return actuators used for two-position control 
applications.
