Parker DFplus Series Directional Proportional Valve

Brand and Model : Parker DFplus Series

General Description

The Parker DFplus series includes high-dynamic, high-precision proportional directional valves designed to control hydraulic flows in complex industrial applications. Parker's DFplus valves are known for their fast response capability and precise pressure and speed control. Major models include pilot operated valves (such as D30FP) and direct operated valves (such as D1FP, D3FP), each suitable for different system configurations.

Main Components

• VCD® Actuator : Patented technology that allows precise cursor movement.
• Slider and Coil : Allow 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 depending on the model; direct models can achieve high flows with precise control.
• Maximum Operating Pressure : Typically up to 350 bar, but detailed specifications depend on the model.
• Operating Temperature : From -20°C to +80°C, depending on the construction materials.

Usage Procedure

1. Installation : Mount the valve using the NG06 or NG10 interfaces, ensuring the system is free of impurities.
