Directional Spool Valve H-4WEH25E6X/6EG24NK4SO6 - Bosch Rexroth R900961153

Which ports are connected in the centre position decides the coasting and holding behaviour of the axis. The H-4WEH25E6X/6EG24NK4SO6 uses symbol E for that, passes up to 700 l/min and withstands 350 bar operating pressure.

Benefits

• Spool symbol E with three switching positions and four ports in size 25.
• 700 l/min flow at 350 bar maximum operating pressure.
• 17.91 kg weight, mounting pattern ISO 4401-08-08-0-05, pilot operated spool.
• External pilot oil supply and external pilot oil return, independent of the main circuit load pressure.
• 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals, HL hydraulic fluid.

Applications

The valve is used on large hydraulic axes where the centre position governs behaviour at standstill. On the same subplate it can be exchanged against other symbols of size 25. The pilot stage runs on a separate pilot oil circuit.
