    Rotary Actuators

    MSxx03 Diamond Series 27 lb-in. Spring Return Direct Coupled Actuators

    Used within heating, ventilating, and airconditioning (HVAC) systems to drive a variety of quarter-turn, final control elements requiring spring return fail-safe operation.

    Overview

    Honeywell has long been a leading name in actuators, and the Diamond Spring Return Actuator is the latest addition to the popular Honeywell lineup. You can count on the Diamond Actuator to support your product with reliable performance day in and day out. A simplified shaft adapter and integral conduit connector saves space and eliminates the need for additional tools or conduit connectors, and 360-degree conduit connectors swivel allowing for easy conduit installation at almost any needed angle. The combination of high quality, small size and competitive price makes the Diamond Actuator the perfect choice for high-volume, low-torque applications, including: rooftop units, economizers, compact control dampers and control valves.
