D111FPE52LA4NB70

The top-level series of pilot operated servo proportional valves D*1FP is the ultimate choice for highest accuracy in positioning of hydraulic axis and controlling of pressure and velocity. It shows extremly high dynamics combined with high flow. ItThe D*1FP series transfers the advantages of the Parker patented Voice Coil Drive (VCD®) to larger frame sizes and thus high flow rates. The high dynamics/ high precision drive of the pilot valve allows the optimum control of the main spool and results in servo class performance of the complete valves.

The D*1FP series is available in 5 sizes:

Features:

• Highest dynamics - shorter cycle times and thus higher machine output
• High flow capacity - optimum efficiency in relation to valve size
• High-resolution position feedback on main spool - assures stable spool position
• Progressive main spool design (sinus characteristics) - high-resolution position control at small command signals and for high flows where desirable
• Defined spool positioning at power-down - optional P-A/B-T or P-B/A-T or center position (for overlapped spools)
• Digital electronics - permits to store and load valve records
• Optionally with EtherCAT interface, 2x M12x1, connector 4-Pin (Ether-CAT In and EtherCAT Out) - high dynamics can be also utilized within the fieldbus system
• Very robust valve design - lower costs through less downtime
• Short delivery time - no warehousing necessary
