General Description Series D*1FB pilot operated proportional directional valves come in 4 sizes: D31FB NG10 (CETOP 5) D41FB NG16 (CETOP 7) D91FB NG25 (CETOP 8) D111FB NG32 (CETOP 10) The valves are available with and without onboard electronics (OBE). D*1FB OBE: The digital onboard electronics is situated in a robust metal housing, which allows usage under rough environmental conditions. The nominal values are factory set. The cable connection to a serial RS-232 interface is available as an accessory. D*1FB for external electronics: The parameters can be saved, changed and duplicated in combination with the digital power amplifier PWD00A-400. Series D*1FB valve parameters can be edited with the common ProPxD software for both versions. The D*1FB valves work with barometric feedback of the main stage to the pressure reducing pilot valve. The pilot control pressure of 25 Bar (363 PSI) allows high flow rates of maximum of stability. The innovative integrated regenerative function into the A-line (optional) allows new energy saving circuits for differential cylinders. The hybrid version can be switched between regenerative mode and standard mode at any time.
Features • Progressive flow characteristics for precise adjustment of flow rate. • High flow capacity. • Digital onboard electronics. • Center position monitoring optional. • New: Switchable regenerative hybrid version.
