  • a parameter may, for example, be the nominal flow rate. Different nominal flow rates for valve modules of the same external shape and size can be achieved, for example, by different slide stroke lengths and / or slider diameters. Without changes to the pilot module and connection plate, adjustments to the performance data of the valve module are possible based on the available space and component dimensions. These may be flow rate adjustments, flow restrictions (eg due to slide stroke and / or pump diameter limitation) and / or a realization of a controlled slide opening behavior (flow is controlled by cycled actuation of the slide actuating piston by means of pilot air modulation against a spring) act. For flow variation, it is also possible to switch between non-overlapping and non-overlapping valve modules.
