ML7984
Honeywell ML7285 spring return direct coupled actuators provide proportional damper control. It uses a current or voltage signal from an electronic controller to position a damper at any point between fully open/closed.
Overview
Honeywell ML7984 linkage mounts onto V5011 two-way or V5013 three-way valves and provides up to 25 mm of linear travel (stem lift). Use with Series 70 2-10 Vdc, 4-20 mA; Series 90 135 ohm; and Super Mod modulating signal controllers.
Features
- Uses 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-in.)
- Strong valve seat closing force of 160 lbf (710 N)
- Multi-pose mounting and compact size for easy installation
- One device for Vac or Vdc power supply application
- Electronic current sending provides internal protection and positive full-closing force
- Available field-addable position feedback/auxiliary switch module
