Parker D3FPE50YB9NS00 Directional Control Valve

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.

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.

Features:

• 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
