Proportional Directional Valve 4WRKE10W8-100L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901146772

Long return paths with cooler and filter build up back pressure. The 4WRKE10W8-100L-3X/6EG24EK31/F1D3M therefore drains its pilot oil through a dedicated line and controls its 100 l/min nominal flow unaffected by it.

Benefits

• 100 l/min nominal flow at 315 bar maximum operating pressure.
• Pilot oil supplied internally, drained externally, back pressure in the main return never reaches the pilot stage.
• Spool symbol W8, flow up to 170 l/min in size 10.
• 4...20 mA command into the on-board electronics, wired through a 7-pole (6 + PE) plug.
• 8.33 kg, NBR seals and three switching positions.

Applications

The valve is used on manipulators, forging presses and systems with a large cooling and filtering loop in the return. Branched return manifolds then no longer disturb control. The Y line has to be present at the subplate.
