Honeywell ML7984 Direct Coupled Valve Actuators, Non-Spring, Modulating

Direct Coupled Valve Actuators, Non-Spring, Modulating

The ML7984 is a self-contained, self-adjusting, motorized linkage that mounts directly onto V5011 two-way or V5013 three-way valves and provides up to 25 mm (1") of linear stem travel. For use with Series 70 2-10Vdc, 4-20mA; Series 90 135 ohm; and Electronic (Super Mod) modulating signals. controllers.

• Allows the use of one common transformer power supply for multiple actuators and controllers.
• Self-contained, motorized valve linkage.
• Linkage self-adjusts to valve stroke from 12 to 25 mm (1/2" to 1").
• Multi-pose mounting.
• Strong valve seat closing force 710 Newton (160 lbs.).
• Compact size for easy installation in confined area.
• One device for either Vac or Vdc power supply application.
• Electronic current sensing provides internal protection and positive full closing force.
