Honeywell ML7420A3055-E Reset The Electric Valve Actuator IP54 24 VAC/VDC

Product Highlights
The ML7420A3055-E is a spring-return electric valve actuator designed by Honeywell for building automation and HVAC systems. It is compatible with DN65-DN150 ball and butterfly valves, provides 20 N·m of torque, 90° of travel, and a switching time of ≤75 seconds at 24 VAC/VDC. After a power outage, the spring return function quickly returns the valve to the safe position in ≤20 seconds, ensuring system safety.

Product Features
The actuator features a die-cast aluminum housing and metal gear assembly, with an IP54 protection rating. It can operate continuously in environments with temperatures ranging from -20°C to 60°C and 5% to 95% relative humidity (non-condensing). A built-in brushless DC motor and Hall-effect position feedback enable continuous adjustment from 0 to 10 V or 2 to 10 V. It also features a 0 to 100% mechanical position indicator and two mounting interfaces: a U-shaped clamp or a square shaft, providing exceptional adaptability.

Compatibility and Expansion
The terminal blocks feature a tool-free quick-crimping design and include a manual wrench for easy commissioning. The product is CE, UL, and cUL certified and RoHS compliant, with a mean time between failures (MTBF) of ≥ 75,000 cycles.

Exemplary Applications
The ML7420A3055-E is widely used in office buildings, hospitals, data centers, and other applications. It seamlessly integrates with Honeywell building management systems (EBI and WEBs-AX) to achieve precise flow control and energy-saving operation, making it an economical choice for improving HVAC system efficiency and reliability.
