Simulation-Based Design of a Direct-Operated Proportional Pressure Relief Valve

摘要

The development of pressure relief valves does not only put requirements on pressure-flow-characteristics, but also requires the maintenance of sufficient dynamics and stability. To accomplish this task the simulation methods support the designing and optimization stage of the functional subsystems of a direct-operated proportional pressure relief valve. Therefore, an inverse simulation model is built for this valve type. CFD and FEM modeling techniques are applied to parameterize the control edge and solenoid performance. A final comparison between measurement and simulation results demonstrates the applicability and accuracy of used simulation methods for the valve design process.
