A piezo bender is the innovative core element of VEAA and VEAB. These valves offer high-precision flow control at up to 20 l/min. with low hysteresis,
high repeat accuracy and low energy consumption. The proportional characteristics of a directly actuated piezo bender ensure stable and reliable regulation, and an infinitely variable pressure rise. The VEAA and VEAB are completely quiet during operation, which is very interesting for many industry
segments.

With a choice of various valve series with different working pressures, nominal widths, flow ranges and working temperatures, Festo offers you the optimal proportional valve for your needs.
