Proportional Directional Valve 4WRKE10E50L-3X/6EG24TK31/A1D3M - Bosch Rexroth R900737629

A position-controlled axis needs a characteristic curve without a step. The 4WRKE10E50L-3X/6EG24TK31/A1D3M guides its spool through internal position feedback, follows the ±10 V command linearly and passes 50 l/min at the nominal point, up to 170 l/min at peak.

Benefits

• 50 l/min nominal flow, up to 170 l/min peak in size 10 on the ISO 4401-05-05-0-05 pattern.
• ±10 V command applied directly at the valve, the on-board electronics close the spool position loop without an external amplifier.
• Pilot oil supplied externally, returned internally, so pilot pressure stays independent of the main circuit.
• 315 bar maximum operating pressure with spool symbol E and three switching positions.
• 8.35 kg, NBR seals, HL hydraulic fluid, supplied at 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve serves position-controlled feed axes on machine tools and test rigs that have to reach defined points repeatably. External pilot supply suits plants that generate pilot pressure centrally. As a pilot-operated spool valve it mounts on a subplate to ISO 4401-05-05-0-05.
