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
