Abstract :
A dynamic nonlinear model of a commercial proportional pressure valve, type Lucifer Honeywell EPP3 J-21-U-100-10, is formulated in order to simulate its behavior in time-domain under several operating conditions. The mechatronic design of the valve and its static and dynamic characteristics are analyzed carefully. Then, the modeling of the valve is carried out by taking into account its main internal devices, which are integrated all together inside the valve in order to allow the pressure control through an input electric signal. Finally, some diagrams given by a computer simulation confirm the validity of the proposed dynamic nonlinear model for this type of proportional valve
