Proportional Directional Valve 4WRKE16W8-220L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R901465088

A manifold without separate X and Y lines saves plumbing. That is what this variant is built for, since pilot oil supply and pilot oil return both stay internal. The pilot-operated main spool carrying symbol W8 handles 220 l/min nominal flow.

Advantages

• Internal pilot oil supply and internal pilot oil return, no extra lines
• 220 l/min nominal flow at 350 bar maximum operating pressure
• Plus/minus 10 V command into the on-board electronics
• Spool symbol W8, three switching positions, four ports
• ISO 4401-07-07-0-05 interface, 11.2 kg

Technical data

Applications

Compact manifolds where every extra drilling costs space benefit most. The valve works in forming machinery and hydraulic test benches running HL oil. Where tank back pressure is high, the external return version is the better pick.
