Proportional Directional Valve 4WRKE10W8-50L-3X/6EG24TK31/A1D3M - Bosch Rexroth R901049770

While a lift table holds full load, system pressure often drops. The 4WRKE10W8-50L-3X/6EG24TK31/A1D3M therefore draws pilot pressure externally and keeps control of its 50 l/min nominal flow steady even then.

Benefits

• Pilot oil supplied externally, drained internally, pilot pressure stays independent of system pressure.
• 50 l/min nominal flow, up to 170 l/min, spool symbol W8.
• ±10 V command with internal spool position feedback.
• 315 bar maximum operating pressure in size 10, ISO 4401-05-05-0-05 pattern.
• 12.02 kg, wired through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve works on scissor lift tables, lifting platforms and cylinders that hold loads over longer periods. External port X is usually fed by a small fixed displacement pump. Pilot oil returns internally into the tank channel, so a Y line is not required.
