    Rotary Actuators

    MSxx10 88 lb-in. and MSxx20 175 lb-in. Spring Return Direct Coupled Actuators

    MS3110, MS3120, MS4110, MS4120, MS7510, MS7520, MS8110, MS8120 Spring Return Direct Coupled Actuators (DCA) are used within heating, ventilating, and air-conditioning (HVAC) systems.

    Overview

    MS3110, MS3120, MS4110, MS4120, MS7510, MS7520, MS8110, MS8120 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.

    Applications include 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 and linear stroke globe or cage valves mounted with linkages to provide linear actuation.
