These compact but powerful direct-coupled ControlSet® actuators provide fast and accurate tri-state floating or two-position control for dampers or valves in HVAC systems. A minimum torque of 25 (MEP-4201), 45 (MEP-4501), or 90 (MEP-4901) in-lb. is available over the 95° angular rotation in 35 seconds or less (or 45 seconds for the MEP-4901).

These non-fail-safe models are designed for use with floating thermostats or controllers or for two-position control (dependent on wiring and switch configuration). A patent-pending noise reducer provides whisper-quiet operation.

All actuators mount directly to 1/4- to 5/8-inch (6 to 16 mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm) square shafts, eliminating the need for expensive and complicated linkages. A non-rotation bracket, to prevent lateral movement, is included with each actuator. A gear disengagement button allows easy manual positioning of the actuator.

(For similar actuators with fail-safe, see the MEP-4200/4500/4900 Series.)
