Directional Spool Valve H-4WEH25J6X/6EG24NK4SO12 - Bosch Rexroth R901034414

Large cylinders need flow, but also a defined centre position at standstill. The H-4WEH25J6X/6EG24NK4SO12 offers both, 700 l/min throughput with the three-position symbol J, at 350 bar maximum operating pressure.

Benefits

• 700 l/min flow at 350 bar maximum operating pressure in size 25.
• Spool symbol J with three switching positions, so a defined centre position exists.
• External pilot oil supply and external pilot oil return for a self-contained pilot circuit.
• 16.98 kg weight, mounting pattern ISO 4401-08-08-0-05, four ports.
• 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals, HL hydraulic fluid.

Applications

Valves like this control presses, lifting gear and large feed axes whose cylinders take several hundred litres per minute. The centre position of symbol J defines how the drive behaves when de-energised. The separate pilot circuit keeps the pilot stage independent of load pressure.
