A pressure compensating flow control valve assembly for providing a constant flow rate for fluids having a high solids content is disclosed. The valve assembly includes a housing comprising first and second housing members having an inlet and an outlet, respectively, a deflectable diaphragm clamped between the housing members and which divides the housing into first and second chambers, and a control valve means carried by the diaphragm which includes a fixed control orifice in communication with the second chamber and outlet and a poppet valve for throttling flow of fluids from the inlet to the first chamber. The control valve means is constructed such that the fluid is caused to be moved in a tortuous path through the valve assembly so as to prevent or minimize solids in the fluid from settling out.
