    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.

    Features & Benefits:
    • Brushless DC submotor with electronic stall protection for floating/modulating models
    • Floating/Modulating models can provide twoposition (SPST) control
    • Brush DC submotor with electronic stall protection for two-position models
    • Self-centering shaft adapter (shaft coupling) for wide range of shaft sizes
    • Access cover to facilitate connectivity
    • Metal housing with built-in mechanical end limits
    • Spring return direction field-selectable
    • Shaft position indicator and scale
    • Manual winding capability with locking function
    • Sylk-enabled models available
    Certifications:
    • UL (cUL) listed
    • Plenum-rated per UL2043
    • CE 89/336/ECC, 73/23/EEC
    • C-Tick N314
