Hygienic AWH Sampling Valve - now EHEDG certified


We make hygiene affordable. A claim that is now backed up by the enhanced AWH sampling valve. When it comes to determining taste, appearance, and microbiological and chemical values, taking accurate samples is paramount. Our EHEDG-certified sampling valve was specially designed for this purpose. An EHEDG inspection certificate further underlines how easy it is to clean, meaning your products will not be contaminated when used properly. The AWH sampling valve comes in three different versions with a variety of port types for a wide range of applications, whether in the weld-in, weldon or screw-in version.

Pneumatic Sampling Valve

With the hygienic, pneumatic compact air sampling valve, there is also an automatic sampling system with additional manual actuation in the AWH portfolio. The sampling valve has a clamp connection in accordance with DIN 32676 and is compatible with the AWH Connect tank connection flange system. Our design is based on the tried-and-tested hygienic sampling valve with manual operation. Upon request, an optional flushing connection can be attached for this version. This means that a connection to an automated CIP/SIP system is possible. In addition to the various predefined versions in the AWH sampling portfolio, customer-specific solutions can also be implemented.

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 The multiple-use membrane automatically closes when the cannula is withdrawn.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.
