Applications involving water intended for human consumption

SAMSON solutions

The strict hygiene requirements which are placed on valve
materials that come into contact with water intended for humanconsumption are particularly challenging.

We recommend the following SAMSON products in installations for water intended for human consumption:

National and international regulations stipulate various requirements which must be observed for valves used with water intended for human consumption.

•The SAMSON Type 3226 Valve as well as the Type 43-3
Temperature Regulator in the versions listed in this document
fulfill these requirements making them suitable for used ininstallations for water intended for human consumption.
German ordinance on the quality of water intended for humanconsumption
The German ordinance on the quality of water intended for human consumption (TrinkwV 2001) includes provisions concerning
protection to human health from the adverse influences resulting
from any contamination of water intended for human consumption. The German national legislation corresponds to the Directive 98/83/EC on the quality of water intended for human consumption.

•The German ordinance basically stipulates that water intendedfor human consumption must meet the limits and requirements of
the ordinance.
Domestic distribution systems are required to distribute and store
water intended for human consumption. Such systems include therelated pipework, fittings and appliances which are installed between the point at which the water passes from the supply network to the user and the tapping point (section 3 in the German
ordinance TrinkwV 2001). As a result, SAMSON valves fall within the scope of the German ordinance on water intended for human consumption. Section 17 of the ordinance regulates the approval of materials that come into contact with water, e.g. materials in pipelines, gaskets and valves. It is important that the materials do not leach substances into the water (e.g. as a result ofcorrosion) and impair the quality of the water. The German environmental protection agency has drawn up a positive list of approved materials.
