Brushless servo motors – more control for valves with linear actuators

Process industry engineers are looking to more sophisticated motion control solutions for valve automation because of an ever-growing need to improve productivity, increase efficiency, and minimize downtime.

These engineers must control the valves that regulate the flow of materials throughout a facility, and there are two basic ways to control these valves: linear motion (rising stem) and rotary motion (half turn or quarter turn). Powered rising stem valves are often used in mission-critical areas of a process. In these applications, reliability, repeatability, accuracy, and responsiveness are crucially important. These factors impact the type of valve actuation specified. There are traditional methods: pneumatic or hydraulic actuated systems and electric linear actuators driven by brush servo motors. Then there’s an emerging technology: brushless servo motor driven electric valve actuators.

Electric linear actuator selection tips: Rod or rodless

When you need to specify a linear actuator, you want to do it right. Some basic decisions come first. Like electric or pneumatic. If you're going with electric, you’ll next need to decide if a rod or rodless linear actuator is the best choice. We offer both types of electric linear actuator, so you can count on us for motion control advice and application expertise.
