This paper proposes a design methodology for designing the mechanical topology in hydraulic Active Check Valves (ACVs). These valves may have optimised flow geometries to obtain fast switching and high flow rates. Furthermore, ACVs comprise large pressure differentials and high deceleration during plunger and seat impact, which introduces a concern about the severity of long term fatigue and wear. A modelling framework of ACVs with the desired capabilities is multidisciplinary involving analysis of mechanics, fluid dynamics, contact mechanics and material science. Therefore, a state-of-the-art focusing on the significant contributions of these disciplines has been conducted. The literature review is focusing on lifetime models and wear concerned with valve seat inserts (VSI) in different fatigue cycle regimes. No studies with direct application have been found, making this work an infant step towards lifetime prediction of ACVs. However, studies of similar systems have pinpointed the mechanisms that result in wear particles. It is the main objective to uncover the parameters with greatest significance when considering lifetime estimation of ACVs and a conceptual formulation of a lifetime framework is established.
