Product Description

The Honeywell ML7984A3019 is a direct-coupled, non-spring return linear valve actuator designed for precise control in HVAC and building automation systems. This actuator mounts directly onto V5011 two-way or V5013 three-way globe valves, providing linear stem travel between 1/2 inch (13 mm) and 1 inch (25 mm). It is compatible with modulating control signals such as 2–10 Vdc, 4–20 mA, and 135-ohm potentiometer inputs, making it versatile for various control systems. The actuator features a strong valve seat closing force of 160 lbf (710 N), ensuring reliable performance in demanding applications. Please note that the ML7984A3019 has been discontinued and replaced by the ML7984A4009 model, which offers enhanced features and improved performance.​
