Parker DFplus Series Directional Proportional Valve

Make and Model : Parker DFplus Series

General Description

The Parker DFplus series includes highly dynamic and precise proportional directional valves, designed for hydraulic flow control in demanding industrial applications. Parker DFplus valves are known for their rapid response and precise pressure and speed control. The main models include pilot-operated valves (such as the D30FP) and direct-operated valves (such as the D1FP, D3FP), each suitable for different system configurations.

Main Components

• VCD® Actuator : Patented technology that allows for precise cursor movement.
• Cursor and Spool : Allow for proportionally adjustable flow control.
• Integrated Electronics : Allows direct communication with the main control system, often via modern interfaces such as EtherCAT.
• Mounting : Suitable for NG06 (CETOP 03) and NG10 (CETOP 05) interfaces.
• Installation Position : Can be installed in any orientation for maximum flexibility.

Dimensions and Mechanical Specifications

• Mounting Dimensions : NG06 (CETOP 03) or NG10 (CETOP 05).
• Maximum Flow : Varies by model; direct models can achieve high flows with precise control.
• Maximum Operating Pressure : Generally up to 350 bar, but detailed specifications depend on the model.
• Operating Temperature : -20°C to +80°C, depending on construction materials.

Usage Procedure

1. Installation : Mount the valve using the NG06 or NG10 interfaces, ensuring that the system is free from impurities.
2. Electrical Connection : Connect the onboard electronics to the main control system.
3. Calibration : Configure control parameters through the control system.
4. Operation : Use the valve to adjust the hydraulic flow to meet the specific needs of the application.

Compatible Accessories

• Flow Controller : For fine adjustment of flow parameters.
• Position sensors : To monitor and correct the cursor position in real time.
• EtherCAT interfaces : For fast communication with the main system.

Sectors of Use
