Directional Spool Valve H-4WEH25E6X/6EG24TK4 - Bosch Rexroth R901029979

As soon as cylinders with large areas have to extend within a reasonable time, flow becomes the bottleneck. This pilot-operated size 25 directional spool valve carries up to 700 l/min while holding a maximum operating pressure of 350 bar. It works with spool symbol E in three switching positions and four ports.

Benefits

• 700 l/min rated flow for cylinders with large displacement
• 350 bar maximum operating pressure
• ISO 4401-08-08-0-05 mounting pattern for size 25
• External pilot oil supply with internal pilot oil return
• 12.8 kg weight, spool symbol E

Technical data

Applications

The valve belongs in presses, lifting gear and forming machines with large cylinder volumes. At 700 l/min it supports rapid traverse movements for which size 16 valves would be too small. Pilot operation requires an available pilot pressure that is fed in externally.
