Manifold valve body and method for producing the manifold valve body

A valve assembly for processing of process fluids comprising:

• a manifold valve body comprising a plurality of valve seats which are accessible by means of respective openings, a plurality of threaded holes being provided around each opening, a plurality of studs being arranged, in portions, in the threaded holes in order to arrange a valve drive on the relevant opening, wherein at least one of the studs that is associated with the relevant opening comprises a first electronic data carrier for contactless identification of the relevant valve seat, wherein the first electronic data carrier is accessible from the outside of the valve assembly, and wherein the valve body is formed in the nature of a one-piece manifold;
• a plurality of valve drives associated with the plurality of valve seats, wherein a second electronic data carrier is arranged on each of the valve drives, and wherein the second electronic data carrier is accessible from the outside of the valve assembly;
• and
• a plurality of diaphragms clamped between the manifold valve body and the associated valve drive closing the associated opening peripherally in a fluid-tight manner, each of the plurality of diaphragms comprising a tab projecting outwards and in which a third electronic data carrier is arranged, wherein the third electronic data carrier is accessible from the outside of the valve assembly.
