Directional Spool Valve 4WEH32HE6X/6EG24N9SK4 - Bosch Rexroth R900727921

An external pilot circuit gives the pilot stage fixed conditions, no matter what happens in the main channel. The 4WEH32HE6X/6EG24N9SK4 uses that in size 32 at up to 1100 l/min and 280 bar.

Benefits

• Pilot oil fed in and drained externally, constant conditions at the pilot stage.
• 1100 l/min flow at 280 bar maximum operating pressure.
• Spool symbol E, 3 switching positions, 39.56 kg weight.
• ISO 4401-10-09-0-05 pattern with 4 ports in size 32.
• 24 VDC solenoid actuation through a 3-pole (2 + PE) plug to EN 175301-803, NBR seals.

Applications

The valve works on presses, rolling mills and hoists with their own pilot supply. Because the pilot circuit is routed separately, switching times stay the same under changing loads. Given the weight, a lifting aid is recommended for installation.
