The valve is a proportional integral derivative (PID) controller ideal for use in industrial control systems found in process, packaging and water and wastewater applications. The incorporation of an external sensor, means friction, hysteresis and leakage are effectively cancelled out which enables engineers to build faster and more accurate machines and systems, while enhancing the quality and efficiency of their processes. Significant time savings can also be made, even in simple pressure regulation, with the sensor integrated into the system.
The setpoint value, initial pressure and external sensor’s signal can be viewed in real time on the oscilloscope, and parameters can be easily adjusted for the optimum control characteristics, with set values recorded for future use.
“The valves can be easily adapted to specific tasks, and its simple operation with self-explanatory graphical support reduces the effort required during programming and speeds up commissioning,” says Steve Sands, product manager at Festo. “Plant managers and operators can now be constantly aware of the internal pressures of their systems, and as such, use this valuable data to ensure they are operating efficiently. The VPPX gives users increased freedom and flexibility and can also be used for more complex applications with FCT.”
