Directional Spool Valve 4WEH16J7X/6EG48N9S2K4 - Bosch Rexroth R901044701

On the 4WEH16J7X/6EG48N9S2K4 pilot oil arrives from a circuit of its own and returns to it. In size 16 the valve handles 300 l/min at 280 bar maximum operating pressure, switches three positions with spool symbol J and runs on 48 VDC. It weighs 10.82 kg.

Benefits

• External pilot oil supply and external pilot oil return, pilot stage independent of working pressure
• 48 VDC supply voltage for plants on that control level
• 300 l/min at 280 bar maximum operating pressure, spool symbol J
• 3 switching positions across 4 ports, ISO 4401-07-07-0-05 hole pattern
• 10.82 kg, NBR seals, HL hydraulic fluid

Application

A fully separated pilot circuit is chosen when working pressure swings widely or disappears at times, as in accumulator charging circuits and press circuits with unloading phases. A small auxiliary unit or a side circuit then feeds the pilot stage. The subplate remains the standard size 16 plate.
