Directional Spool Valve 4WEH10D4X/6EG125N9K4 - Bosch Rexroth R901387223

A pilot-operated directional valve separates switching force from flow and therefore moves considerably more oil in size 10. The 4WEH10D4X/6EG125N9K4 uses that for 160 l/min at 280 bar maximum operating pressure.

Benefits

• 160 l/min at 280 bar in size 10, pilot-operated through a stage of its own.
• Spool symbol D with 2 switching positions on the ISO 4401-05-05-0-05 pattern.
• Pilot oil fed in and drained externally, independent of the main channel.
• 125 VDC supply voltage, 3-pole (2 + PE) plug to EN 175301-803.
• 6.92 kg, NBR seals, UKCA conformity under Low-Voltage Directive SI2016/1091.

Technical data

Applications

The valve controls main axes of smaller presses, die cushions and test rigs that already run a pilot circuit. Because pilot supply and pilot drain are external, pilot pressure stays steady even when working pressure fluctuates. The 125 VDC coil fits plants with a rectified valve level.
