Directional Spool Valve 4WEH32W6X/6EG24K4QM0G24/B10 - Bosch Rexroth R901379546

In rapid traverse the pressure in the main channel often drops a long way, yet the pilot stage still needs it. The 4WEH32W6X/6EG24K4QM0G24/B10 solves this with a fully external pilot oil path and switches up to 1100 l/min in size 32.

Benefits

• Pilot oil fed in and drained externally, switching pressure stays independent of the main channel.
• 1100 l/min flow at 280 bar maximum operating pressure on the ISO 4401-10-09-0-05 pattern.
• Spool symbol W with three switching positions across four ports in size 32.
• 24 VDC through a 3-pole (2 + PE) plug to EN 175301-803, solenoid actuation of the pilot stage.
• 36.01 kg weight, NBR seals for HL hydraulic fluid.

Applications

The valve is used on presses and lifting gear whose main pump alternates between load and idle operation. A dedicated pilot pressure circuit, often fed by a small auxiliary pump, keeps switching times equal at every operating point. The mid position function follows spool symbol W.
