In the application and development of pneumatic techniques, Matrix products represent the most advenced and the most innovative choice. Matrix technology allows the use of the most modern techniques of pressure and flow control.

Pneumatic solenoid valves may be subdivided into two categories: digital on/off and proportional solenoid valves. Digital solenoid valves combine their open-close position with an electric on-off control. Proportional solenoid valves combine a particular position –between open and close- in a proportional way with tension or variable-current control device.

The evolution of technology led to the development of new flow control techniques, which allow the use of digital components instead of proportional ones. These techniques are PWM (Pulse Width Modulation), PFM (Pulse Frequency Modulaton), PNM (Pulse Number Modulation) and PCM (Pulse Code Modulation), besides combinations between them (Combined Techniques)
