AEL8 Series Electric Linear Actuator
Description The AEL8 Series linear electric actuators are a cost effective range of linear electric process actuators, with diagnostics, only suitable for the modulation of Spirax Group valves. The AEL8 Series actuators must not be used for any other purpose. Full nomenclature details can be found on page 7 of this document. Simple to select and commission, the AEL8 series is especially suited to process point of use applications within the steam ecosystem where robustness and reliability are key requirements. The AEL8 Series is compatible with the complete Spira-trol™ 2-port and 3-port ranges.
The AEL8 Series linear electric actuators utilise a fully electronic set up and operation of the actuator with no mechanical switches or manual intervention required. The direct measurement of valve position, stroke and force guarantee optimised process control, and all actuators have internal anti-rotation for improved actuator rigidity. Diagnostics The AEL8 series actuator provides actuator diagnostics through 3 functions: - Non-intrusive health check hand wheel
4.3 57
- Self-diagnostic LED - (Optional) Fault relay
Typical applications The AEL8 series actuators are used for the modulation of Spirax Group valves in closed-loop and open-loop control systems. Typical applications for the AEL8 Series actuator include: - Temperature control - Pressure control
- Flow control - Level control
For boiler feed water applications please refer to the AEL7 (TI-P713-02)
