In our days the development of electro-pneumatic equipment has allowed their use in high-performance control systems with applications in various industrial sectors and adapted to various industrial technologies. This paper proposes a method for maintaining a constant air flow rate in pneumatic installations, regardless of pressure fluctuations, using an electro-pneumatic servomechanism. The system consists of a linear pneumatic actuator and a proportional pneumatic valve that actuates a butterfly valve positioned on the discharge pipe of a turbo compressor. A proportional controller, combined with real-time feedback from a flow meter, ensures accurate regulation of the valve opening. The proposed method is validated through numerical simulations performed in the Simcenter Amesim environment, based on experimental data obtained from previous studies. Simulation results demonstrate the system’s ability to maintain a stable flow rate under varying pressure conditions and different consumer demands. This approach offers a practical and scalable solution for flow regulation in industrial air networks.
