Safety Warning

Full Product Description

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. It  The 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:
• D31FP NG10 (CETOP 05)
• D41FP NG16 (CETOP 07)
• D91FP NG25 (CETOP 08) for port diameter up to 32 mm
• D111FP NG32 (CETOP 10)

Optionally available with EtherCAT® interface
The valves series D*1FP with EtherCAT® interface fulfill  the requirements of modern communication between valve and main control. Due to high data transmission speed and short cycle times, the high dynamics can be also utilized within the fieldbus system.

Markets:
• Industrial
• Machine tools
• Molding

Features/Benefits:
• 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)
• IO-Link interface for parametrizing
• RGB diode for optical status check
• NFC interface
• 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

Applications:
• General presses
• Die cast
• Injection molding
• Pulp & paper

Technical specifications:
The safety concept works with a safe 4th position at the D1FP pilot valve. This ensures that the main stage is hydraulically balanced at power down and allows to have the main spool spring centered (for overlapped spools) or approximately 10 % spring offset to spool position A or B (for zerolap spools).

Note: The versions with Regenerative or hybrid function are no longer available.
