Honeywell ML7420A3055-E Reset The Electric Valve Actuator IP54 24 VAC/VDC
The Honeywell ML7420A3055-E is a high-torque, spring-return electric actuator designed for reliable modulation or on/off control of HVAC dampers, air valves, and industrial quarter-turn valves in commercial and light industrial applications. Part of Honeywell’s trusted ML7420 Series, this 90° rotary actuator delivers precise positioning, fail-safe operation, and long service life—making it ideal for use in air handling units (AHUs), exhaust systems, boiler controls, and energy recovery ventilators.
Featuring a 24 V AC/DC universal power supply, modulating control input (0–10 V DC or 4–20 mA), and automatic calibration, the ML7420A3055-E ensures seamless integration with building management systems (BMS), DDC controllers, and PLCs. Its spring-return (fail-safe) design automatically drives the valve to a pre-defined safe position during power loss—critical for smoke control, fire safety, and process shutdown scenarios.
