Directional Spool Valve H-4WEH25D6X/6EG24N9TS2K4 - Bosch Rexroth R900704860

At low pressure in the main circuit, pilot oil taken from the valve port itself can become too weak. The H-4WEH25D6X draws pilot oil from an external source and returns it internally, at 700 l/min of flow.

Benefits

• External pilot oil supply secures switching even at low pressure in the main circuit.
• Internal pilot oil return, which saves an additional line.
• Spool symbol D with two switching positions across four ports.
• 700 l/min at a maximum operating pressure of 350 bar.
• 18.54 kg, ISO 4401-08-08-0-05 connection diagram, 24 V DC solenoid, NBR seals.

Technical data

Applications

Plants with accumulator operation or long rapid-traverse phases run at low main pressure for part of the cycle. An external pilot source keeps switching times predictable there. The internal return keeps the manifold simple.
