Festo - Proportional pressure control valve VPPI
Accurate and highly dynamic!
Controlled in silence
With the VPPI proportional pressure control valve, all nominal sizes are controlled directly; without the need for pilot valves or pre-stages. Due to the pressure compensating element, the valve regulates dynamically and precisely; even at the larger nominal sizes. The powerful and low-friction voice coil makes the VPPI highly dynamic. The integrated position controller contributes to high stability.
Preset or custom? Both!
The direct control with three preset values - for small or large volumes or continuous flow - allows the valve to be controlled very dynamically. A customer-specific presetting independently defines the corresponding control behavior and speeds up the setting of the desired value.
Fully graphic TFT display
All necessary settings can be made via the display. Much of the information is available in clear text.
Highly flexible
When the VPPI detects a pulse-width modulation (PWM) signal within a frequency range of 200 - 800 Hz, the internal control electronics automatically adjust. The set pressure range can be controlled at a high level from 20 - 100%. In addition, signals can switch to digital inputs up to seven preset values.
Best performance
The VPPI can regulate in the vacuum range as well as pressures up to 12 bar. The nominal dimensions are identical in both flow directions.
