Proportional Directional Control Valves Series D1FX, 30 Design Bulletin 2583-M1/USA Technical Information General Description The D1FX Series of proportional directional control valves provide variable output flow in response to voltage or current command signals. The valves are fully integrated units with on-board electronics and a spool position feedback device. Features • Integral Electronics ¾ Eliminates the time consuming and often costly electrical wiring between valve and driver card.
Proportional Directional Control Valves Series D1FX, 30 Design Bulletin 2583-M1/USA Functional Description (Version AJ) Options and Adjustments section. Not all jumpers and potentiometers are functional on every version. 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 feedback loop closures made external to the valve.
Wiring & Initial Setup (Version AJ) Proportional Directional Control Valves Series D1FX, 30 Design Initial Startup Interface Wiring, 6 Pin I/O Connector Bulletin 2583-M1/USA EHC** 8 Cable Factory Settings: LVDT hydraulically nulled (R3) Max A and Max B adjusted fully CW JP3 inserted: X1 Cmd gain Bias set for 0 V (R1) Initial Startup: Turn on the DC power supply. Apply the Command input Slowly increase the system pressure Cycle the command and verify that the flow is proportional to the input.
Proportional Directional Control Valves Series D1FX, 30 Design Bulletin 2583-M1/USA Functional Description (Version BJ) European Version BJ The command input accepts either voltage or current inputs and has differential input capability for noise immunity and easy reversal of phasing. Output flow is proportional to the spool position which follows the adjusted command signal. The spool position may be observed at TP1 or at Pin F. Reference voltages are not available.

Proportional Directional Control Valves Series D1FX, 30 Design Bulletin 2583-M1/USA Functional Description (Versions DJ & DK) Standard Driver with Deadband Eliminators — Versions DJ and DK The standard D1FX valve may not, depending on the load, be electrically symmetrical about the no-flow condition. Occasionally, (such as when using a PLC generated signal) it is desirable to equalize the signal needed for similar flow from P to A and P to B.

Options & Adjustments Proportional Directional Control Valves Series D1FX, 30 Design Spool Position Monitoring Reference Voltages (AJ,CJ,CK,DJ,DK) The spool position relative to its zero starting point can be observed at TP1. Reference voltages are available for wiring to potentiometers for Cmd or Fdbk inputs. Up to 10 mA current is available but a 10 K ohm pot is recommended. The potentiometer can be wired for either a ± voltage or for a single polarity as shown below.
Options & Adjustments Proportional Directional Control Valves Series D1FX, 30 Design Min Adjustments (cont.) Bias (All versions) To adjust: Bulletin 2583-M1/USA • Remove Cmd and Fdbk inputs. Bias should be set for 0 V. The command bias is factory set to 0 VDC. It can be used with a current input or PLC to provide bidirectional flow.
Proportional Directional Control Valves Series D1FX, 30 Design Bulletin 2583-M1/USA Trouble-Shooting Symptom Cause Solution Instability Power supply? Select a power supply not current limited below 4.0 Amps. Use a separate power supply for each valve. The power supply should be chassis grounded. Noise on inputs? To verify, disconnect input signals to D1FX. Jumper Cmd and Fdbk terminals to common. For best results use a separate ground wire for signal inputs and power supply.
Proportional Directional Control Valves Series D1FX, 30 Design Bulletin 2583-M1/USA Installation Information Torque Specifications FOR MAXIMUM VALVE RELIABILITY, ADHERE TO THE FOLLOWING INSTALLATION INFORMATION The recommended torque values are for the bolts which mount the valve to the manifold or subplate are as follows: NFPA Size Fluid Recommendations D03 Premium quality mineral based hydraulic oil with a viscosity range between 150-250 SSU (32-54 cst.) at 38°C (100°F) is recommended.
