Electric actuators
Overview
Spirax Sarco electric actuators provide reversible linear motion for control valves that need dependable on-off or modulating operation, with the AEL6 platform aimed specifically at users who want smarter valve actuation rather than a basic motor only. For many international steam and process plants, electric actuation is attractive where compressed air consumption needs to be reduced, electrical integration is simpler than instrument air infrastructure, or commissioning time has to stay predictable across multiple valves. The AEL6 series combines analogue input and feedback handling, automatic commissioning, travel scaling and onboard diagnostics in one compact package, helping the actuator learn the installed valve stroke and reduce setup effort after installation or replacement. Stored operating data, torque monitoring and status visibility support a more proactive maintenance approach, making it easier to identify actuator drift before it affects control stability or process consistency. Compared with air-powered alternatives, electric actuators can reduce routine utility demand while still supporting accurate remote valve positioning on modulating duties where repeatability matters. These actuators are typically paired with Spirax Sarco control valve assemblies where users need a complete valve package with clearer diagnostics, easier setup and stronger long-term visibility of actuator condition.
Related actuation routes
Electric actuation should be matched to the valve body and the wider package. Continue into steam control valves when the actuator is part of a full modulating valve assembly, and compare pneumatic actuators when plant air and fail action still make an air-powered solution more suitable.
If feedback and diagnostics strategy matter alongside the drive choice, add valve positioners.

Actuator choice affects commissioning effort, energy use, diagnostics visibility and how well the valve package fits the plant control strategy.
See the wider control package context
Return to the wider control systems range when electric actuation is only one part of a larger valve package or loop design decision.
Pair the actuator with the right valve
Use the control valve range when the next step is matching thrust, stroke and valve characteristic to the installed process valve body.
Compare electric and pneumatic actuation
Compare pneumatic actuators when plant air is preferred, faster diaphragm response is required or the control strategy already relies on instrument air.
