Abstract: A valve block for a piggable and/or solid-state conducting line system of a process technical plant can include one or more rotary control valves. The rotary control valve(s) can include one or more line inputs, one or more line outputs, and a rotatable control member with one or more through-channels. In an open position, a line input of the one or more line inputs is connected to a line output of the one or more line outputs through a through-channel of the one or more through-channels. In a closed position, the first control member separates the one or more line inputs from the one or more line outputs. The rotary control valves are rotatable about a same rotation axis and the control members are non-rotatably connected to each other. The one or more through-channels of respective rotary control valves are offset plane-parallel relative to each other in an axial direction of the rotation axis.

Abstract: The invention relates to a spring-elastic measuring element (1) for thermometers, pressure switches or manometers consisting of an arc-shaped measuring tube (3), a base body (2) and a connecting element (10) for the measuring mechanism. The aim of the invention is to achieve the fully automated welding of the thermally influenced zone and to improve the latter. To achieve this, the connections between the measuring tube (3) and the base body (2) and the measuring tube and the connecting element (10) are obtained using connecting elements (11, 12) that can be welded. This allows the risk of contamination of the measuring system to be eliminated to a great extent and reduces the formation of corrosion and vibration cracks by the use of a small thermally influenced zone. A connecting element (11, 12) can also be produced as one-piece with the measuring tube (3) by expanding or creating a bead on the latter.
