Honeywell Commercial ML6420A3049 Valve Actuator

Honeywell Commercial ML6420A3049 Valve Actuator is a high‑performance SPDT, direct‑coupled electric actuator designed for precise 2‑position control in HVAC systems. It delivers reliable, floating linear motion from a 24 Volt AC supply, ensuring accurate valve positioning with minimal overshoot.

Built for rugged environments, this actuator features a non‑spring return design, 24 VAC operation at 50/60 Hz, and a 135 in‑lb torque rating for robust valve movement. The enclosure is IP54 rated and constructed from ABS‑FR plastic with an aluminum yoke, providing durable performance in typical plant conditions. With a 3/4 inch stroke and a 60‑second travel time, it offers responsive control for dampers and valves in commercial HVAC installations. It carries UL, CSA, and CE approvals and uses a screw terminal connection for easy wiring. The compact size (5-5/16 in W x 6-5/16 in D x 9-9/16 in H) fits tight controller spaces, while operating temperatures from 14 to 122°F keep it reliable across seasons.
