Proportional Directional Valve 4WRZE10W9-85-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R901311256

Smaller axes need less flow yet the same signal robustness. This pilot-operated size 10 model meters 85 l/min from a 4...20 mA command value and holds operating pressure up to 315 bar, with spool symbol W9.

Benefits

• 85 l/min nominal flow in size 10, maximum flow 170 l/min.
• Mounting pattern ISO 4401-05-05-0-05, mass 8.48 kg, clearly lighter than a size 16 body.
• Pressure reducing valve in the pilot circuit with internal supply plus internal return.
• Current command value 4...20 mA, supply 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals for warm oil, hydraulic fluid class HL, conformity UKCA.

Applications

The valve drives infeed axes as well as clamping axes on machine tools, test rigs and smaller presses. Spool symbol W9 across 3 switching positions sets the behaviour in mid position. A concealed manual override helps whenever the axis has to move without control voltage.
