The ML7420A / ML7425A,B actuators are designed for modulating control with controllers providing an analog output of 0...10 Vdc or 2...10 Vdc. They operate Honeywell’s standard valves in heating, district heating, ventilation, and air conditioning (HVAC) applications. Spring-return models provide a safety position at power failure

FEATURES • Easy and quick installation • No separate linkage required • No adjustments required • Low power consumption • Force-limiting end stops • Spring-return models (ML7425A,B) • Manual operation knob • Position feedback signal • 0...10 Vdc or 2...10 Vdc signal input selectable • Direct / reverse action selectable • Stroke position on signal failure selectable • Corrosion-resistant design • Maintenance-free
