Electrohydraulic Vs Pneumatic Actuators for butterfly valve

Hello

Any advantage of using an electrohydraulic actuator for a 30 inch butterfly  valve instead of pneumatic ? which one is better in terms of performance ?   butterfly valve is for control, gas application.

Thank you

  • Hi Yacine, there are performance advantages using an electro-hydraulic actuator vs. a pneumatic actuator and it depends on your application. But in general, electro-hydraulic typically has better control compared to pneumatic actuators as air is compressible while hydraulic fluid utilized by electro-hydraulics actuators are not compressible. Also, if the pneumatic air is not clean, it will vary your performance with a pneumatic actuator.
