Parker’s CFD Controlled Flow/Priority Type Flow Divider divides pump hydraulic oil into two separate flows. One, the pressure compensated controlled flow (has Priority), and the other, a usable flow which is in excess of the controlled clow. The controlled flow rate is determined by the metering spool that is installed.
