Electric Actuator
Brand: Spirax SarcoThe AEL6 series of smart electric linear actuators are suitable for fitting to our range of SPIRA-TROL and QL control valves.
This new series of actuator features positioning speeds of up to 4.5 mm per second, which means that this actuator is now fast enough to be used on applications where previously only pneumatic actuation was suitable.
With increasing pressure on companies to reduce carbon emissions, we are seeing an increased demand for electrically actuated valves as they consume less energy and produce fewer carbon emissions over their lifetime when compared to a pneumatic actuator.
Features- Reduced lifetime cost – as energy consumption is lower.
- Reduced carbon emissions.
- Reduced plant downtime, through quick, easy installation and commissioning.
- Ability to develop preventative maintenance schedules.
