The valve drive AZURA® Valve Unifier VU 4.1 enables automatic valve switching. Due to its low switching time, the flow path is interrupted only for a very short time, and the pressure peaks are reduced to a minimum. The valve drive can be operated with software as well with an optional touch display (Mobile Control) or via LAN. Valves are identified via innovative RFID technology, which guarantees an easy valve exchange of KNAUER valves with RFID technology. This RFID technology enables to read GLP data, for example the maintenance of the rotor seal exchange is simplified by automatic notifications.
