Directional Spool Valve 4WEH32H6X/6EG24NTSK4 - Bosch Rexroth R901113263

How a large directional valve fits into the control block depends on the routing of the pilot oil. On the 4WEH32H6X/6EG24NTSK4 it is supplied externally and returned internally, at 900 l/min flow and 280 bar operating pressure.

Benefits

• External pilot oil supply, internal pilot oil return, a separate return line is not needed.
• 900 l/min flow at 280 bar maximum operating pressure in size 32.
• Spool symbol H with three switching positions and four ports.
• 35.9 kg weight, mounting pattern ISO 4401-10-09-0-05, pilot operated spool.
• 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals, HL hydraulic fluid.

Applications

The valve controls large cylinders whose pilot pressure comes from a source of its own. The internal return assumes that the tank channel of the main circuit is relieved well enough. The centre position of symbol H defines how the axis behaves when de-energised.
