Directional Spool Valve H-4WEH25J6X/6EG24N9K4 - Bosch Rexroth R900929180

When residual pressure builds up in the return line of a system, the pilot oil needs its own path to tank. This size 25 version therefore supplies and drains pilot oil externally and switches 700 l/min at a maximum operating pressure of 350 bar using spool symbol J.

Benefits

• Spool symbol J in three switching positions with four ports
• External pilot oil supply and external return, independent of return line pressure
• 700 l/min rated flow at 350 bar maximum operating pressure
• 17.31 kg weight on the ISO 4401-08-08-0-05 pattern
• NBR seals and HL hydraulic fluid at 24 V DC

Applications

It is installed in control blocks of presses and test rigs where return filters or coolers create back pressure. Because the pilot circuit stays separate, switching times do not shift with system pressure. Ports and mounting follow the standard for size 25.
