Overview

The ML6984 and ML7984 are self-contained, self-adjusting, motorized valve actuators that mount directly onto V5011 twoway and V5013 three-way globe valves, providing linear stem operation between 1/2 in. (13 mm) and 1 in. (25 mm). 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 ohm modulating controllers

Features

  • 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 of 1/2 to 1 in. (12 to 25 mm)
  • Multi-pose mounting
  • Strong valve seat closing force 160 lbf (710 N)
  • Compact size for easy installation in confined area.
  • One device for either 24 Vac or 28 Vdc power supply application
  • Electronic current sensing provides internal protection and positive full closing force
  • Field-addable position feedback/auxiliary switch module available (5-wire control wiring only)
  • ML6984 models are compatible with 3-wire control systems
