Direct Operated Proportional DC Valve Series D1FP

Transcription

1 Catalogue HY11-500/UK Characteristics The direct operated control valve D1FP of the nominal size NG0 (CETOP 0) 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 50 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. Technical features Real servovalve dynamics (- db / 50 Hz at ±5 % input signal) No flow limit up to 50 bar pressure drop through the valve Max. tank pressure 50 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 D1FP UK.indd RH
