Directional Spool Valve H-4WEH25E6X/6EG24NK4 - Bosch Rexroth R900958090

The valve reverses flows of up to 700 l/min at a maximum of 350 bar. Spool symbol E gives the centre position defined behaviour, and the pilot stage is fed and drained externally. Subplate mounting follows ISO 4401-08-08-0-05.

Benefits

• 700 l/min flow, 350 bar maximum operating pressure, size 25
• Spool symbol E with three switching positions for defined behaviour in the centre
• External pilot oil supply and external pilot oil return, independent of main circuit pressure
• 24 V DC, connector 3-pole (2 + PE) according to EN 175301-803, NBR seals
• 17.94 kg weight with four ports to ISO 4401-08-08-0-05

Application

The version is used in machine tools, presses and test rigs with high oil demand. The centre position of symbol E decides how the actuator behaves as soon as the solenoids are de-energised. NBR seals are provided for HL hydraulic fluid.
