The new VPWI is based on the VPPI and can be used for all applications where volume control is required. It offers extremely short operating times, a stable valve position and extensive functionality, from setpoint adjustment to an
MFC-like function, making the VPWI extremely fl exible in use.

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.

To help future dentists and dental assistants deal with children during dental treatments, the Japanese company tmsuk has developed a humanoid robot that realistically simulates the behaviour of young children during these treatments, complete with fidgeting, flinching or closing the mouth. The dummy’s realistic movements are produced using proportional pressure regulators with piezo technology.
