Direct Coupled Valve Actuator

ML6984

The ML6984 is a self-contained,

self-adjusting, motorized linkage that mounts directly onto V5011 two-way or V5013 three-way valves and provides up to 25 mm (1 in.) of linear travel (stem lift). For use with low voltage 3-wire SPDT Series 20

(on-off); Series 60 (floating)

electromechanical (dry contacts);

or electronic (triac output)

controllers.
