Information
This is a model of a pressure compensating valve with lumped volumes. If the pressure difference between the closing and opening pilot ports is higher than pMin, the valve starts to close. When the pressure difference reaches pMax, the valve is fully closed. The spool model has first-order dynamics with time constant t1.
Implementation
This valve basically consists of an orifice controlled by a spool.Parameters (8)
