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.
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.
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)
• No flow limit up to 350 bar pressure drop through the D1FP valve
• Max. tank pressure 350 bar for D1FP, 250 bar for D3FP (with external drain port y)
• High flow
• Defined spool positioning at power-down - optional P-A/B-T or P-B/A-T or center position (for overlapped spools)
• Onboard electronics
• Optionally with EtherCAT interface
• Optionally with freely configurable supervising control circuit (D1FP*D, D3FP*D)
• Analogue sensor input (D1FP*D, D3FP*D)
Benefits for Users:
• Optimized cycle times through enhanced valve dynamics
• Enhanced product quality due to higher valve precision
• Minimized failure thanks to robust valve design
• Digital electronics permits to store and load of valve records
