The aim of the study was to optimize the flow of compressed air through a pneumatic directional control valve by optimizing the valve design. The 3D model of the valve was constructed in a CAD SolidWorks program. The assumptions concerning the performance included low friction, a small pressure loss, and accordingly high flow parameters, i.e. sonic conductance and critical pressure ratio. Ansys CFX, a computational fluid dynamics program, was used to simulate and optimize the flow of compressed air through the valve, and examine the basic flow characteristics. By optimizing the fluid flow at an early design stage, it will be possible to produce directional control valves with improved flow parameters.
