APPLICATION
The ML6984 and ML7984 are self-contained,
self-adjusting, linear motorized valves that mount directly
onto V5011 two-way and V5013 three-way globe valves,
providing linear travel (stem lift) between 13 mm (1/2”)
and 25mm (1”).
ML6984 is for use with low voltage SPDT Series
20 (on-off) and Series 60 (floating) electro-mechanical
or electronic controllers. ML7984 is for use with Series
70 2-10 Vdc, 4-20 mA, electronic series 90, 135 Ω and
modulating controllers.
