Proportional Directional Control Valves
Series D1FX, 30 Design
Functional Description (Version AJ)
Configuration Definition
The D1FX is supplied in two basic configurations —
non-feedback and feedback. Non-feedback refers to
valves having only a command input with any feed-
back loop closures made external to the valve.
Feedback refers to valves having input terminals for
both command and feedback and electronics for
proportional loop closure. All the D1FX versions
incorporate an internal spool position feedback.
The non-feedback versions include the Standard
driver (AJ), a European version (BJ), and deadband
versions (DJ & DK).
Feedback versions (CJ & CK) provide for external
proportional feedback.
Detailed setup instructions can be found in the
Options and Adjustments section. Not all jumpers
and potentiometers are functional on every version.
Installation
Refer to the back of the manual for fluid recommenda-
tions, mounting restrictions, and other general installa-
tion instructions.
Standard Driver — Version AJ
Refer to the Functional Block diagram in figure 1.
This is the standard 24 VDC version which accepts
either a voltage or current command input. Output
flow is proportional to the spool position which follows
the Adjusted Command signal. ± 10 V reference
voltages are available on Pins A and F of the I/O
connector for a command potentiometer.
