The VEAA and VEAB feature an innovative drive component – a piezo bender. 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 piezo bender with direct actuation ensure stable and reliable regulation – and a stepless pressure rise. Especially interesting for many industry segments is that the VEAA and VEAB operate entirely silently.
