ML7984 Valve Actuator

PRODUCT DATA

APPLICATION

The ML7984 is a self-contained, self-adjusting, linear motor-

ized 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-congurable DIP switches for Series 70 / 90 control-

ler

• Field-congurable 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)

• Separate models available for V5011/13 A and C or

V5011/13 F and G valve body types

• Self-contained, motorized valve linkage.

• Linkage self-adjusts to valve stroke of up to 19 mm (3/4”)

• Multipoise mounting

• Strong valve seat closing force 710 Newton (160 lbs.)

• Compact size for easy installation in conned areas

• Electronic current sensing provides internal protection and

positive full closing force

• Field-addable auxiliary switches available

ML7984 Valve Actuator Assembly of ML7984 to the valve: POSITION INDICATOR (PLASTIC DISK) 1. The drive shaft of the ML7984 has a threaded hole to link with the valve stem. Slide the yoke over the valve bonnet (Fig 4) 2. Thread the ML7984 drive shaft onto the valve stem all the way, until it is completely attached (with no threadsshowing), by turning the valve actuator in a clockwise direction, as viewed from above (depending on the valve models, use a pin or wrench to keep valve stem from turning).
