Proportional Directional Valve 4WRKE10E100L-3X/6EG24EK31/A1D3V - Bosch Rexroth R901249044

A cylinder axis has to move at an even rate over the full stroke although the load keeps changing. The pilot-operated proportional directional valve 4WRKE10E100L-3X/6EG24EK31/A1D3V passes 100 l/min nominal flow, works up to 315 bar operating pressure and corrects spool position through internal position feedback before the deviation becomes measurable at the axis.

Benefits

• 100 l/min nominal flow in size 10, with headroom up to 170 l/min maximum flow
• 315 bar operating pressure on the ISO 4401-05-05-0-05 pattern, matching any standard subplate of this size
• Command value ±10 V straight into the on-board electronics, so no separate amplifier card is needed in the cabinet
• Internal pilot oil supply saves one feed line, while the external pilot drain keeps the pilot stage clear of tank line back pressure
• Spool symbol E, FKM seals, 8.38 kg, matched to HL hydraulic fluid

Applications

The valve serves feed and lifting axes on presses, test rigs and special purpose machines that meter a flow of this order without steps. Subplate mounting allows a direct swap against an identical size 10 valve without altering the manifold. Control is by 24 VDC through the 7-pole plug to EN 175201-804.
