Proportional Directional Valve 4WRKE10W6-50L-3X/6EG24EK31/A1D3M - Bosch Rexroth R900719667

When the return line of a system builds up back pressure, the zero point of the pilot stage shifts. The 4WRKE10W6-50L-3X/6EG24EK31/A1D3M avoids that by tapping pilot oil internally and relieving externally, at 50 l/min nominal flow with spool symbol W6.

Benefits

• Internal pilot supply, external pilot drain, the pilot stage relieves through a line of its own.
• 50 l/min nominal flow, up to 170 l/min throughput in size 10.
• Spool symbol W6, three switching positions, four ports on the ISO 4401-05-05-0-05 subplate.
• ±10 V command, on-board electronics, spool position fed back internally.
• 8.37 kg, NBR seals, HL hydraulic fluid, operating pressure up to 315 bar at 24 VDC.

Applications

Systems with a return filter or a cooler gain a stable pilot pressure from this variant. The 50 l/min nominal rating fits medium feed, clamping and slewing axes. The Y line has to run separately to tank.
