The principle of piloted relief valve is introduceded. The simulation model of piloted relief valve is estab- lished by using the simulation software AMESim, and the main parameters of the model are set to achieve different simulations of this valve both in normal condition and common fault conditions. The simulation results show that all kinds of fault response can be simulated expediently with this kind of simulation,which offers a valuable referrence for fault diagnosis and fault prediction of piloted relief valve.
