Abstract
This paper evaluates the modeling, simulation, and practical implications of a 4/2‑way valve ("4/2‑crack") using Festo FluidSIM for pneumatic and hydraulic systems. We present methodology for accurate simulation, parameter sensitivity, performance metrics, control strategies, and recommended best practices for design and experimentation. Results include simulated flow/pressure responses, dynamic behavior under varied loads, and guidelines for translating simulation to bench tests.
