Vario Sampling Valve
The AWH Vario version is a sampling valve that can take product samples in two ways. Firstly, in the conventional way using the sampling tube; in addition, by means of a cannula, which is pushed through the membrane to take samples via a syringe or tube. The multiple-use membrane automatically closes when the cannula is withdrawn. Contamination from outside is thus reduced to a minimum.
