APPLICATION
The ML6984 and ML7984 are self-contained, self-
adjusting, motorized valve actuators that mount directly
onto V5011 two-way and V5013 three-way globe valves,
providing linear stem operation between 1/2 in. (13 mm)
and 1 in. (25 mm).
ML6984 is for use with low voltage SPDT Series 20, Series
60 (on-off), or SP3T Series 60 (floating) electro-
mechanical and electronic controllers.
ML7984 is for use with Series 70 0-10 Vdc, 2-10 Vdc, 4-20
mA; electronic Series 90 “SuperMod”; and 135 ohm
modulating controllers.
