Proportional Directional Valve 4WRKE35W6-1000P-3X/6EG24K31/F1D3M - Bosch Rexroth R901227838

In systems with a dedicated pilot power unit the main stage should switch independently of the working circuit pressure. The 4WRKE35W6-1000P-3X/6EG24K31/F1D3M therefore takes its pilot oil externally and returns it externally while metering 1000 l/min nominal flow at 350 bar.

Benefits

• External pilot oil supply and external pilot oil return - the pilot stage stays operational even with a decompressed main circuit.
• 1000 l/min nominal flow in size 35 at 350 bar operating pressure, up to 3000 l/min by design.
• 55 kg weight, roughly 14 kg less than the internally piloted versions of the same series.
• Command value 4 to 20 mA through a 7-pole connector (6 + PE) to EN 175201-804, supply 24 V DC.
• Symbol W6 with a linear characteristic including fine control range and internal spool position feedback.

Application

The valve is intended for large hydraulics with a separate pilot circuit, such as presses with decompression phases, water engineering and heavy test equipment. On the ISO 4401-10-09-0-05 interface it is interchangeable with the other size 35 versions. HL hydraulic fluid, NBR seals.
