Abstract
A circuit for change-over of electric signal set points applied as control inputs to a fluid control valve for controlling the pressure or flow rate of a fluid. A priority circuit including a priority encoder or priority chain is provided in an input section for set point select and change-over instruction signals from an external sequential controller. When two or more of the instruction signals are applied simultaneously, only the highest priority instruction is received to select the desired set point and the other instructions are ignored.
