Proportional Directional Valve 4WRTE10W8-100L-4X/6EG24K31/A1V - Bosch Rexroth R901032303

Large cylinders need flow, controlled axes need a predictable characteristic. The 4WRTE10W8-100L-4X/6EG24K31/A1V brings both together, carrying 100 l/min nominal flow with spool symbol W8, staying linear across the whole command range and being piloted externally, at up to 350 bar.

Benefits

• The spool carries symbol W8 and the nominal flow is 100 l/min.
• External pilot oil supply and external pilot oil return separate the pilot circuit from the main circuit.
• Piston travel is measured inside the valve and fed back, and the characteristic curve is linear. Operating pressure reaches 350 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, FKM seals for HL fluid, maximum flow 170 l/min, weight 9.5 kg.

Applications

Valves like this sit in presses, test rigs and handling axes with a central pilot pump and elevated oil temperature. External draining through Y keeps return pressure out of the pilot stage. Internal spool feedback secures repeatable positions over the service life.
