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.
