| Underperforming control valves and dampers will cost a typical process plant tens of thousands of dollars each year. The performance of these key devices is crucial to plant efficiency. Their direct impact on energy consumption, process downtime, recurring maintenance costs, and consistent product quality has significant influence on any facility's profitability.
Exlar electric servo actuators provide a perfect solution for your valve actuation needs. Small hysterisis and dead band, quick response to small signal changes and stable dynamic response are all key parameters that Exlar actuators deliver.
Available in both linear and rotary versions, Exlar actuators can be mounted on any valve from any manufacturer.
They are the Perfect Electric Valve Actuator

High Performance for Sliding Stem Valves
Exlar actuators combine a high performance brushless servo motor, and specially designed roller screw mechanism for converting electrical motor power into linear motion. Exlar actuators continuously hold the position of the valve stem or shaft allowing extremely fast response to command signal changes even when stiction is present; easily providing positioning accuracy of 0.25% or better. |
Eliminate Rotary Conversions for Ball Valves
The Exlar rotary actuators allow you to directly couple the actuator to the shaft of the valve, eliminating all linear to rotary linkages needed by pneumatic actuators. With gear reductions up to 100:1, the Exlar rotary actuators can be mounted to most modulating ball, plug and butterfly valves. |
Reliable Damper Control
To provide tight control of windbox airflow, it is imperative that damper blades respond to signal changes as small as 0.25% full scale. For this reason, windbox retrofits are now replacing pneumatic actuators or induction motor actuators with Exlar electric actuators for both accuracy, and lower maintenance. |
