APPLICATION
The ML7984 is a self-contained, self-adjusting, linear motorized
linkage that mounts directly onto V5011 two-way or
V5013 three-way valves and provides up to 19 mm (3/4”)
of linear travel (stem lift). For use with Series 70 2-10Vdc,
4-20mA electronic and Series 90 135 Ω, Electronic (Super
Mod) modulating signal controllers.
FEATURES
The ML7984 valve actuator provides the following features:
• Allows the use of one common transformer power supply for multiple actuators and controllers
• Field-configurable DIP switches for Series 70 / 90 controller
• Field-configurable DIP switches for Direct / Reverse action
• Field-selectable terminals for 2-10Vdc / 4-20 mA signal input
• One device for either Vac or Vdc power supply application
• Compatible with 3 -wire system (one common wire for both signal & power inputs)
