Non-spring return direct-coupled Valve Actuator with 160 lbf rated force
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
