Static and dynamic characteristics of a two stage relief valve have been studied theoretically and experimentally. The governing equations of the valve have been derived and sensitivity analysis was performed by digital computer simulation on the valve response characteristics based on the established dynamic equations of the motions of the valve. From this study, significant parameters on the valve response were identified, which can be modified to improve the dynamic characteristics of the valve. Subsequently, experiments were performed with a specially fabricated Vickers type pilot relief valve. The results showed fair agreement with the simulation results, thus proving the validity of the model.
