Spring Return Direct Coupled Actuator

S05 Series (MS4105; MS7105; MS7405; MS7505; MS8105)

MS4105, MS7405, MS7505, MS8105 Spring Return Direct Coupled Actuators (DCA) are used within heating, ventilating, and air- conditioning (HVAC) systems. They can drive a variety of quarter-turn, final control elements requiring spring return fail-safe operation.

FEATURES

•Volume control dampers, mounted directly to the drive shaft or remotely (with the use of accessory hardware).

•Quarter-turn rotary valves, such as ball or butterfly valves mounted directly to the drive shaft.

•Linear stroke globe or cage valves mounted with linkages to provide linear actuation.
