Directional Spool Valve 4WEH32E6X/6EG24N9SK4QM0G24 - Bosch Rexroth R901029655

At 1100 l/min the force of a switching solenoid is no longer enough to move the spool. The 4WEH32E6X/6EG24N9SK4QM0G24 is therefore pilot-operated, switches in size 32 to symbol E and runs with external pilot oil supply and return.

Benefits

• 1100 l/min maximum flow in size 32 to connection diagram ISO 4401-10-09-0-05.
• External pilot oil supply and return, keeping the pilot stage independent of the main circuit.
• Spool symbol E with 3 switching positions and 4 ports.
• Solenoid actuation on 24 V DC, connected through a 3-pole plug (2 + PE) to EN 175301-803.
• 280 bar maximum operating pressure with NBR seals and HL hydraulic fluid.
• 17 kg weight with subplate mounting.

Applications

The valve directs flow in the main circuits of large presses, forging equipment and rolling mills. External pilot oil routing makes sense where the main circuit is unloaded while switched and the pilot stage still needs oil. At a mass of 17 kg the subplate has to be sized accordingly.
