Simple remote flow setting with new electric speed controller from SMC

SMC launch PFES, an electric speed controller, offering remote control of pneumatic actuator speed with a simple and compact design. It is ideal for installations where access is restricted or puts operators at risk, and it is time saving for applications with multiple speed controllers since the commissioning can be done simultaneously. In case of power loss, PFES retains its last set position ensuring the pneumatic function. Besides pneumatic actuator speed adjustment, PFES is also suitable for the control of air blow or gas purge flow rates.

Simple electric control 

Replacing traditional manual flow controllers, PFES uses an electrically operated needle valve to regulate compressed air flow. Operators can send open or close signals from a remote location, making it possible to adjust actuator speed in clean rooms, guarded machinery, or elevated installations — without entering the machine area.  

Efficient and safe speed setting 

PFES helps reduce commissioning and maintenance time by allowing multiple speed controllers to be adjusted simultaneously using a single remote signal. This eliminates the need for manual setting on each unit and avoids inconsistencies between machines. The valve’s grease-free construction also makes it suitable for sensitive applications, such as direct air blow onto products, where potential contamination must be avoided. 

Manual override and power-loss resilience 

During machine commissioning, PFES allows manual adjustment even if electrical controls are not yet in place. This flexibility speeds up build and setup processes and ensures that local adjustments can still be made if needed. In the event of power loss, PFES retains its last set position, maintaining pneumatic function without requiring a reset or homing procedure. Manual adjustment remains possible, ensuring continued control even in challenging conditions. 

“This all-in-one control solution does not require complex drivers, controllers or software and forms an efficient alternative to manual speed controllers.” Says Product manager Fredrik Edholm and concludes “Mechanical engineers can easily integrate the valve into their existing systems, supporting digitisation and automation without the need for specialist electrical expertise.”
