Smart valve drive with RFID-technology


Valve drive for valves V 4.1

The valve drive AZURA® Valve Unifier VU 4.1 enables automatic valve switching. Due to its rapid switching, the flow path is only interrupted 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. An additional feature is the easy monitoring of GLP data, which simplifies 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.

Valves perform many different tasks in liquid chromatofrafic systems (HPLC). They act as flow switches and control the direction of the flow in the HPLC system. Valves are indispensable for eluent selection, sample injection, column selection, fractionation, and switching tasks. KNAUER valves are also frequently used outside of HPLC - e.g. for dosing applications in the chemical industry. With KNAUER valves you are flexible regarding the choice of materials and bore sizes as well as drivers for different software packages. The AZURA VU 4.1 valve drive supports over 40 valve types for a wide range of applications.
