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

Technical data

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.
