Product Description

The Honeywell M845E4001 is a Modutrol IV™ electric actuator designed for precise control of valves and dampers in HVAC and industrial applications. It features a 1-minute stroke time, 160° rotation, and operates at 120V AC with a power consumption of 25 VA. This actuator is equipped with an integral spring return, ensuring the controlled element returns to its normal position during power interruptions. Its die-cast aluminum housing provides durability, and the unit includes a junction box for NEMA 3 weather protection. The M845E4001 is suitable for use in both normally open and normally closed valve applications.
