Application of the Methodology of Multi-Valued Logic Trees with Weighting Factors in the Optimization of a Proportional Valve

Hydraulic valves are used to determine the set values of hydraulic quantities (flow rate, pressure, or pressure difference) in a system its part. This is achieved through appropriate throttling stream flowing valve, which automatically by operator (e.g., opening throttle valve). The procedures for determining static and dynamic properties were described using example modeling two-stage proportional relief valve. Subsequently, importance design operational parameters was determined multi-valued logic trees. Modeling began with determination equations describing flow movement moving parts Based on equations, numerical model then created, e.g., Matlab/Simulink environment (R2020b). characteristics obtained as result analysis slow changes rate Various coefficients logical products have not been taken into account separable common minimization processes equation systems any available literature. results tests can be optimize several types valve constructions.
