Directional Spool Valve 4WEH16D7X/6EG24N9ETDAL/B10 - Bosch Rexroth R901236006

The 4WEH16D7X/6EG24N9ETDAL/B10 draws its pilot oil internally and returns it internally, so no extra pilot lines have to be run at the manifold. The pilot operated size 16 spool valve passes up to 300 l/min at a maximum operating pressure of 280 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return save two separate lines at the control manifold.
• Spool symbol D with 2 switching positions and 4 ports for circuits with cleanly separated end positions.
• Flow capacity of 300 l/min in size 16 at a weight of 9.46 kg.
• Maximum operating pressure of 280 bar with NBR seals for hydraulic fluid HL.
• Subplate mounting to ISO 4401-07-07-0-05 for interchange with standard valves.
• Solenoid actuation at 24 VDC, connected through a 3-pole connector (2 + PE) to EN 175301-803.

Application

The valve controls pressing, lifting and feed cylinders with a high oil demand. Internal pilot routing assumes that the P gallery always carries enough pressure for the pilot stage. Where that holds, the design saves piping and shortens commissioning.
