Parker Hannifin D3FPE50YA9NB50 - Direct Operated Proportional Directional Control Valve - Series D1FP / D3FP

The direct operated control valves D1FP and D3FP show extremly 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.

Driven by the patented VCD® actuator, the D1FP / D3FP reach the frequency response of real servo valves. At power-down the spool moves in a defined position. All common input signals are available.

Version with EtherCAT interface
The D1FP / D3FP with EtherCAT interface fulfills the requirements of modern communication between valve and main control. Due to high data transmission speed and short cycle times, the high dynamics of the DFplus valves can be also utilized within the fieldbus system.

Version with freely configurable supervising control circuit
DFplus valves D1FP*D and D3FP*D with freely configurable superior control circuit allow the high dynamic control without an additional controller. Via the integrated electronics and an analogue sensor, the valves assume either the precise pressure or position control.

Markets:
• Industrial
• Machine tools
• Molding
• Marine (non military)

Features/benefits:
• 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)
• With EtherCAT interface upon request - high data speeds, short cycle times
• Optionally with freely configurable supervising control circuit (D1FP*D, D3FP*D)

Applications:
• General presses
• Machine tool
• Blow molding
• Marine Diesel fuel injection/exhaust valve control

Additional information EtherCAT version
The valve is actuated and monitored by the EtherCAT interface. Actual value (spool position), temperature, operating hours and different error messages are available as diagnostic signals. The valve parameters are factory set and can be adapted with the Parker ProPxD software via the parametrizing interface.

In addition to the fieldbus communication, the valves provide the range of functions of the standard version including analogue command signal and diagnostic spare stroke. Thus they can be operated independent of the fieldbus control, particularly during commissioning and maintenance.
