Directional Spool Valve H-4WEH25J6X/6EG24N9S2K4/B10 - Bosch Rexroth R901363867

When a cylinder calls for more than half a cubic metre of oil per minute, size 25 is the right stage, because this valve passes up to 700 l/min. The spool with symbol J switches three positions, the main stage holds 350 bar operating pressure and draws its pilot oil from a separate circuit.

Benefits

• 700 l/min flow across the ISO 4401-08-08-0-05 subplate interface
• 350 bar permissible operating pressure in size 25
• External pilot oil supply and external return, control pressure independent of the main circuit
• Spool symbol J with three switching positions across four ports
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803
• 18.64 kg mass, NBR seals for HL hydraulic fluid

Application

Flows of this order occur on press cylinders, lifting gear and test rigs with large piston diameters. A separate control circuit feeds the pilot stage and keeps switching times constant even when the main pressure drops. The subplate interface follows connection diagram ISO 4401-08-08-0-05.
