Proportional directional valve WFCE 3/8 Function, section, symbol Set-up The pilot-operated proportional directional valve type WFCE basically consists of: Cover () Main stage () Pilot control valve with proportional solenoid (3) Integrated electronics with position transducer and analog interface (4) The integrated electronics (OBE) compare the specified command value to the position actual value of the control spool of the main stage (). In case of control deviations, the solenoid of the pilot control valve (3) is activated. In this way, the control spool is adjusted. Depending on the control deviation, the control chamber of the main stage () is either pressurized with pilot oil (the main stage closes) or unloaded (the main stage opens). Stroke and orifice cross-section are controlled proportionally to the command value until the control deviation is remedied. For proper function, the following has to be observed: Direction of flow A B (X connected to A) Direction of flow B A (X connected to B) 4 3 Failure of supply voltage If the minimum supply voltage fails or is fallen below, the enable is disconnected (only interfaces B and G) and in case of a cable break of the solenoid conductor, the integrated electronics (OBE) will de-energize the solenoid of the pilot control valve (3). The control spool of the main stage () moves securely to its seat using the pressure available at port X and the force of the main stage spring and blocks the flow between A and B. Flow control function In connection with a pressure compensator, the pilotoperated proportional directional valve can be used for the pressure-compensated control of a flow.
