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 13 mm (1/2
”
) and 25 mm (1
”
).
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 ohms
modulating controllers.
