Parker D1FP Hydraulic Proportional DC Valve


The direct operated control valve D1FP of the nominal size NG06 (CETOP 03) shows 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 reaches the frequency response of real servovalves. Compared with solenoid driven valves the D1FP can also be used in applications with pressure drops up to 350 bar across the valve. Because of the high flow capability the D1FP can be a substitute for NG10 valves in some cases. At power-down the spool moves in a defined position. All common input signals are available.

Features

  • Real servovalve dynamics (-3 dB / 350 Hz at ±5 % input signal)
  • No flow limit up to 350 bar pressure drop through the valve
  • Max. tank pressure 350 bar (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

1) If valves with onboard electronics are used in safety-related parts of control systems, in case the safety function is requested, the valve elec-tronics voltage supply is to be switched off by a suitable switching element with sufficient reliability
2) For applications with pT>35 bar (max. 350 bar) the Y-port has to be connected and the plug in the Y-port has to be removed.
3) Flow rate for different ∆p per control edge: Qx = QNom. · √ ∆px∆pNom.
4) Measured with load (100 bar pressure drop/two control edges).
