Directional Spool Valve H-4WEH25H6X/6EG24N9K4 - Bosch Rexroth R900949851

The choice of spool symbol decides how the cylinder behaves in mid position. This size 25 version carries spool symbol H and switches up to 700 l/min at a maximum operating pressure of 350 bar. Pilot oil supply and pilot oil return are both routed externally.

Benefits

• Spool symbol H in three switching positions with four ports
• 700 l/min rated flow, 350 bar maximum operating pressure
• Pilot oil supplied and returned externally, independent of tank pressure
• 17.35 kg weight on the ISO 4401-08-08-0-05 pattern
• 24 V DC solenoid with connector, 3-pole (2 + PE)

Applications

Systems with back pressure in the tank line benefit from the external pilot return, because the pilot circuit can then drain without pressure. The valve is used in presses, forging lines and large lifting devices. An external pilot pressure supply is required.
