Directional Spool Valve H-4WEH25E6X/6EG24N9TS2K4/B10 - Bosch Rexroth R901155664

A separate control pump feeds the pilot stage, while the return runs back inside the valve into the tank line. That split suits power units with an unpressurised return and a secured control pressure. The size 25 main stage passes up to 700 l/min at 350 bar and carries spool symbol E.

Benefits

• External pilot oil supply from a separate control pump, internal return into the tank line
• 700 l/min flow at 350 bar operating pressure
• Spool symbol E with three switching positions across four ports
• Connection diagram ISO 4401-08-08-0-05 for the subplate interface
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) according to EN 175301-803
• 19.16 kg mass with NBR seals for HL hydraulic fluid

Application

The field of use is presses and power units that carry a separate control pressure supply. Because the pilot oil comes from that source, switching times survive a drop in working pressure. The return is routed inside the valve and saves one line at the subplate.
