Directional Spool Valve 4WEH16J7X/6EG24N9ESK4/B08 - Bosch Rexroth R900971875

Return filters and coolers build up back pressure on the tank port that the pilot stage should not see. The 4WEH16J7X/6EG24N9ESK4/B08 takes its pilot oil internally and drains it through a separate external return, at up to 300 l/min.

Benefits

• Internal pilot oil supply with external return, the pilot drain stays free of back pressure.
• 300 l/min flow in size 16 across 4 ports.
• Spool symbol J with 3 switching positions.
• 280 bar maximum operating pressure at a weight of 10.82 kg.
• NBR seals, matched to HL hydraulic fluid.

Applications

This combination suits circuits with an occupied tank port, for instance downstream of return filters, coolers or long collecting lines. The pilot drain gets a line of its own while the main flow stays separate. The rest of the layout is standard, subplate mounting to ISO 4401-07-07-0-05 in size 16 with 24 VDC solenoid actuation.
