Direct Coupled Valve Actuators
ML7984 Direct Coupled Linear Valve Actuators
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 - 1")
• Multi-pose mounting
• Strong valve seat closing force 160 bf (710 N)
• 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
• Field-addable position feedback/auxiliary switch module available
