Introducing the PFES Series electric speed controller from SMC, which provides remote management of pneumatic actuator speed with a straightforward and compact layout. Perfect for situations where access is limited or poses risks to operators, the PFES Series allows for secure, effective adjustment of actuator speed without requiring manual involvement. Certainly, the PFES extends beyond pneumatic actuator speed modulation and can additionally be applied for regulating air blow or gas purge flow rates
Simple electric control
PFES utilizes an electrically controlled needle valve to manage the flow of compressed air, replacing conventional manual flow regulators. Operators are able to transmit open or close signals remotely, allowing them to modify actuator speed in clean rooms, secured equipment, or high-altitude setups—without needing to access the machinery zone.
The PFES controller is set up similarly to a traditional flow controller, yet its electric motor enables easy management through “UP” or “DOWN” commands. When the desired configuration is achieved, power can be turned off, and the valve will maintain its position to ensure ongoing function without using energy
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.
Digital-ready performance
PFES offers a straightforward all-in-one control solution that does not require complex drivers , controllers or software. Mechanical engineers can easily integrate the valve into existing systems, supporting digitisation and automation without the need for specialist electrical expertise.
The PFES Series from SMC delivers a smart, safe, and efficient alternative to manual speed controllers—enhancing productivity, reducing risk, and simplifying pneumatic control.
