Proportional Directional Valve 4WRKE10E50L-3X/6EG24EK31/A1D3M - Bosch Rexroth R900706739

A return filter or a cooler builds up back pressure that the pilot stage should not see. The 4WRKE10E50L-3X/6EG24EK31/A1D3M therefore drains through a dedicated external Y line while pilot supply is tapped internally, and it meters 50 l/min nominal flow.

Benefits

• Pilot oil supplied internally, drained externally, the pilot return bypasses back pressure in the tank gallery.
• 50 l/min nominal flow, throughput up to 170 l/min in size 10.
• ±10 V command, on-board electronics, spool position fed back internally.
• 315 bar maximum operating pressure with spool symbol E on the ISO 4401-05-05-0-05 pattern.
• 8.39 kg, NBR seals, HL fluid, driven through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

Systems with a return filter, a cooler or a long tank gallery benefit from external pilot drain, because the pilot stage then relieves without pressure. Clamping and feed axes in presses and machine tools are typical. The Y line has to be routed separately during installation.
