Directional Spool Valve 4WEH16J7X/6EG205N9S2K4 - Bosch Rexroth R900931609

When main pressure and tank line fluctuate, the pilot stage should notice nothing of it. The 4WEH16J7X/6EG205N9S2K4 has separate ports X and Y for that, runs on 205 VDC and passes up to 300 l/min at 280 bar in size 16.

Benefits

• External pilot oil supply and external pilot oil return through ports X and Y.
• 205 VDC supply voltage with a 3-pole connector (2 + PE) to EN 175301-803.
• 300 l/min flow at 280 bar maximum operating pressure.
• Spool symbol J with three switching positions and four ports, pattern ISO 4401-07-07-0-05.
• 9.85 kg weight, NBR seals, HL fluid.

Applications

The valve is intended for plants with accumulator operation where the main pump shuts down at times, and for circuits with a return filter and cooler. Both pilot paths stay independent, so switching time and switching reliability are kept. Size 16 fits into existing blocks to ISO 4401-07-07-0-05.
