Proportional Directional Valve 4WRTE32W8-600P-4X/6EG24K31/F1M - Bosch Rexroth R901038788

In plants with a central control system the current output is often fixed, and the valve has to follow it. The 4WRTE32W8-600P-4X/6EG24K31/F1M processes a 4...20 mA command value, corrects the spool through internal position feedback and provides 600 l/min nominal flow at 350 bar.

Key benefits

• Command input 4...20 mA - connects directly to current output cards with no signal converter.
• 600 l/min under closed loop spool control - internal position feedback makes the flow command repeatable.
• External pilot supply and external drain - the pilot circuit is fully decoupled from the main circuit.
• Linear characteristic with a fine control range - precise metering close to mid travel.
• Spool symbol W8, interface ISO 4401-10-09-0-05 - size 32 subplate mounting with 4 ports and 3 switching positions.
• 37.14 kg, NBR seals - hydraulic fluid HL, supply 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve is used in rolling mills, hydro power plants and large test fields where signal paths are long and the control system delivers current outputs. Its own pilot circuit allows defined positions regardless of pressure in the main circuit. Swapping it for a voltage version would require a change in the controller.

Manufacturer

Made by Bosch Rexroth, material number R901038788. The type code 4WRTE32W8-600P-4X/6EG24K31/F1M is shown on the nameplate and distinguishes this version from the voltage variant.
