ML6984
Honeywell ML6421A, B non-spring return electic linear valve actuators are used with low-voltage, single-pole, double-throw (SPDT), Series 60 two-position and floating controlling. They operatre standard Honeywell valves in HVAC applications.
ML6984A4000/U
Non-spring return direct-coupled Valve Actuator with 160 lbf rated force
Overview
Honeywell ML6984 self-contained, self-adjusting linear motorized linkage mounts directly ont V5011 two-way or V5013 three-way valves and provides up to 25 mm of linear stem travel. Use with low-voltage three-wire SPDT Series 20 (on-off), Series 60 electromechanical or electronic output controllers.
Features
