- In this study, dynamic analysis of a two-step pressure valve is studied. The valve comprises of sliding pistons and pressure chamber to regulate the pressure. It also includes a feedback loop consisting of bellows, poppet and relief valves to achieve self-regulation. The valve includes two functional halves to have failsafe functionality if one valve becomes non-functional. Since accurate pressure regulation can be achieved, this valve finds its application in aerospace industry as an anti-icing value. The principles behind the working of this valve is complex with interaction of physical domains such as mechanical and fluid dynamics. If one or more sub components are not functioning in their effective range, the performance of the valve can deteriorate. So a multi domain dynamic model of a pressure value is implemented in MATLAB/Simulink platform to study the effect of each sub-component on the overall functioning of the valve. First, the functioning of the valve is explained, and underlying working principle of the sub assembly are illustrated. Then, a MATLAB/Simulink model is presented, taking into account the interactions between different physical domains. The response from the dynamic model is correlated with the design targets and the influence of key physical parameters is presented.
