An approach for analyzing and optimizing seal opening pressure of a valve used in automotive application is presented. The seal is made up of Chloroprene rubber with hardness of 70 IRHD. Mooney–Rivlin hyperelastic material model is used to predict the behavior of the seal. The Chloroprene rubber is modeled as an incomparable hyperelasticity material under an assumption of isotropic flow. The behavior of the seal purely depends on the geometry, interference between the seal and housing and also hardness of the seal. The seal opening pressure is optimized by changing the geometry of the seal, and the interference between the seal and housing. In this paper, the existing seal is analyzed with the help of numerical analysis called finite element method. Finally, the optimized seal is manufactured and validated experimentally. The optimized seal met the required seal opening pressure of less than 0.125 MPa.
