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.
