Rexroth 4WRPNH6C1B40L-2X/M/24CF6G

The Rexroth 4WRPNH6C1B40L-2X/M/24CF6G is a high-performance proportional directional valve manufactured by Rexroth (Bosch Rexroth). This valve provides precise, electronically controlled hydraulic flow direction and rate management for industrial machinery and automation systems.

Overview

The Rexroth 4WRPNH6C1B40L-2X/M/24CF6G proportional directional valve delivers smooth, continuously variable control of hydraulic actuator speed and direction in response to electrical command signals. Unlike conventional on/off directional valves, proportional valves enable infinite adjustment of flow rate, allowing precise acceleration, deceleration, and positioning of hydraulic cylinders and motors.

This valve is part of the Rexroth 4WR range, one of the most widely installed families of proportional hydraulic valves in industrial automation worldwide. The range covers nominal sizes from 6 to 35, with flow rates suited to everything from compact machine tools to large-scale industrial presses and rolling mills.

The 4WRPNH6C1B40L-2X/M/24CF6G features high-quality proportional solenoids with linear force-stroke characteristics, precision-machined spool and bore, and optional integrated electronics for simplified wiring and commissioning. The valve is designed for long service life in continuous-duty industrial environments, with contamination-resistant construction and proven reliability.

Key Features

• Proportional flow and direction control from a single compact valve
• Smooth, stepless speed adjustment of hydraulic actuators
• High-quality proportional solenoids with excellent linearity
• Robust industrial construction with long service life
• Compatible with standard Rexroth hydraulic manifolds and control systems
• Industry-standard mounting pattern for easy installation and retrofitting

Applications

Rexroth proportional directional valves like the 4WRPNH6C1B40L-2X/M/24CF6G are used across a wide range of industrial applications including machine tools, hydraulic presses, plastic injection moulding machines, paper and printing machinery, steel processing lines, woodworking equipment, and general industrial automation where precise, variable-speed hydraulic control is essential.
