The LA-2000 Series are self-contained, bi-directional, linear actuators internally geared to produce up to 12,000 lbs. (53,376 N) of thrust, and offer continuous modulating duty up to 2,000 starts per hour. A variety of speeds, thrusts and motors are available which make the LA-2000 Series ideally suited for reliable positioning of dampers, combustion controls, gates, diverters, variable speed drives, or other linear positioning applications. Most LA-2000 Series actuators are also available with an internal amplifier. These amplifiers are all fullfeatured ac or dc switching devices designed to work seamlessly with the actuator for closed loop control.
