Product Overview
▔▔
The direct operated control valves D1FP and D3FP show extremely high dynamics combined with maximum flow. It is the preferred choice for highest accuracy in positioning of hydraulic axis and controlling of pressure and velocity.
Key Advantages
▔▔
• Real servovalve dynamics (-3 dB / 350 Hz at ±5 % input signal) - ideal for demanding applications, ensures optimized cycle times
• Very good repeatability - improved process and product accuracy
• Robust valve design - minimized failure
• Digital electronics - can be easily adapted to the application, resulting in flexible use
• Short delivery time - no storage necessary
• 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
• With EtherCAT interface upon request - high data speeds, short cycle times
• Optionally with freely configurable supervising control circuit (D1FP*D, D3FP*

FAQ
▔▔
Q1: What makes a Voice Coil Drive (VCD) better than a standard proportional solenoid?
A: A standard solenoid uses a heavy iron core which takes time to magnetize and move. The VCD uses a very lightweight coil that moves instantly within a permanent magnetic field. This gives the D1FP a response time under 3.5 milliseconds, which is nearly as fast as a servo valve but at a lower cost.
Q2: What happens to the D1FP valve if the electrical power suddenly fails?
A: The D1FP features a built-in fail-safe option. When power is lost, an internal mechanical spring or electronic backup immediately forces the valve spool into a pre-defined safe position (either central or fully closed), preventing uncontrolled machine movements.
