Abstract
Control valves find one of their most important applications in control loops of process plants for controlling the flow rate of a gaseous or liquid medium. To this end, it is crucial that the flow rate can be reliably adjusted and that safe operation, especially with hazardous substances, can be guaranteed. To solve this problem, a hole pattern for perforated plugs () of control valves is proposed, which allows the densest possible arrangement of openings () on helical lines where the height of the helical lines is minimal and, at the same time, advantageous technical specifications and safety regulations can be taken into account. The pattern allows to generate a very smooth flow characteristic, which facilitates a reliable control of the flow rate. Moreover, the flow rate can be optimized such that the size of the moving parts of the control valve can be reduced to a minimum.
