Characteristics
The direct operated control valve D3FP of the nominal
size NG10 (CETOP05) shows extremly high dynamics
combined with high flow. First of all it is used for highest
accuracy in positioning of hydraulic axis and controlling
of pressure and velocity.
Driven by the new patented VCD
®
actuator the D3FP
reaches the frequency response of real servovalves.
At power-down the spool moves in a defined position. All
common input signals are available.
Technical features
• Real servovalve dynamics
(-3dB/350Hz at ±5% input signal)
• Max. tank pressure 350 bar
(with external drain port Y)
• Defined spool positioning at power-down - optional
P-A/B-T or P-B/A-T or center position
(for overlapped spools)
• Onboard electronics
• Spool / sleeve design

resp. B – T with pressure drops above 120 bar or contamination in
the hydraulic fluid.
