It has one pressure port (P,1), two ports (A,2) and (B,4) that connect to the device that needs to be controlled, and two exhaust ports (EA,3) and (EB,5). They direct the flow of fluid through the system, control flow of fluid, and regulates the pressure of fluids. This function is possible due to the capability of a flow control valve to affect the rate of energy transfer at any given point in a system by impacting the flow rate. Communications: The controller can have the ability to engage in two-way communications with a bus system (for example: communication between the ECU and a display, or output signal to an input device).
