Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R900751835

Replacing an existing axis that runs on a plus or minus 10 V command should not mean rewiring. The 4WRZE10W6-50-7X/6EG24N9EK31/A1D3M serves exactly that input, meters 50 l/min nominal flow with spool symbol W6 and drains the pilot stage separately through Y at operating pressures up to 315 bar.

Benefits

• Spool symbol W6 with 3 switching positions and 50 l/min nominal flow in size 10.
• Pilot oil is taken internally and drained externally through the Y port.
• The built-in pressure reducing valve holds pilot pressure steady while the main circuit runs up to 315 bar.
• On-board electronics process the ±10 V command value at the valve, powered by 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-05-05-0-05, NBR seals for HL fluid, maximum flow 170 l/min, weight 9.22 kg.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Technical data

Applications

The valve is used on feed axes, clamping cylinders and lifting gear with medium flow demand. The separate Y drain keeps the pilot characteristic stable even when filters or coolers build back pressure in the return. On-board electronics save an amplifier card in the cabinet.
