The design of the circuit boards was revised allowing us to use a simplified construction with only one board. To record this constructive change the article number AWA01 was discontinued and replaced by AWA01XA. Please use this new article number for requests or orders. The change does not affect the functionality of the valve drive and the new circuit board is downward compatible.
The valve drive AZURA® Valve Unifier VU 4.1 enables automatic valve switching. Due to its low switching time, the flow path is blocked only for a very short time, and pressure peaks are reduced to a minimum. Valves are identified via RFID technology, which guarantees an easy valve exchange of KNAUER valves with RFID technology. This RFID technology allows to easily check GLP data. and this way to simplify maintenance such as the exchange of a rotor seal. The display enables user-friendly standalone operation. In addition, the valve drive can be operated with software as well with an optional touch display (Mobile Control), via LAN or analog input/output, by which it can be integrated into nearly every LC system.
