Abstract: A valve island has at least one valve module (12) and on a first outer surface (20) a fastening structure (18) extending in a line-up direction (A), in particular for fastening to a mounting rail (24). On at least one second surface (30), which extends substantially perpendicularly to the line-up direction (A), a first and a second electrical contact area (26, 28) are provided, wherein the fastening structure (18) lies between the two electrical contact areas (26, 28).

Abstract: A control head of a fluid measuring device (20, 40) has an outer housing (32) which has a surrounding shell surface (34), an open face side formed by a first opening (50) and facing the device (20, 30), an opposite open face side formed by a second opening (52), and a lateral opening (36) in the shell surface (34). The second opening (52) and the lateral opening (36) have substantially the same opening cross-section. The control head further has first and second closure units (60, 62) which each include a cover and a surrounding luminous ring (66) positioned on a housing side of the cover, the covers of the first and second closure units (60, 62) each being adapted to be configured as a blind cover (64) or as an electronic display (68), and each closure unit (60, 62) being adapted to be releasably coupled to the outer housing (32) both at the second opening (52) and at the lateral opening (36) to close the respective opening (36, 52).

Abstract: An electronic unit of a fluid sensor or fluid valve has a substantially cylindrical housing with a longitudinal axis and an open end face, which can be closed by a lid, several spacers formed as separate parts, which can be introduced into the housing in direction of the longitudinal axis and are directly stacked on top of each other. At least one spacer at least one electronic component is attached, which together with the spacer forms a premounted unit to be introduced into the housing.
