Proportional Directional Valve 4WRKE10W8-25L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R901406646

Every extra line at the subplate costs space and adds a sealing point. The 4WRKE10W8-25L-3X/6EG24ETK31/F1D3M takes pilot oil internally and returns it internally, so the axis runs on 25 l/min nominal flow without separate X and Y ports.

Benefits

• Pilot oil supplied and drained internally, the subplate needs no dedicated pilot lines.
• 25 l/min nominal flow at up to 150 l/min, enough for small and medium cylinders.
• Internal spool position feedback with a linear characteristic curve, commanded by 4...20 mA.
• 315 bar maximum operating pressure in size 10 on the ISO 4401-05-05-0-05 pattern.
• Spool symbol W8, 8.3 kg, NBR seals and HL hydraulic fluid.

Technical data

Applications

The valve suits compact control blocks that only expose P, T, A and B. Typical duties are clamping axes, infeed drives on special purpose machines and small presses. Internal pilot routing shortens the fitting work when a failed valve is exchanged.

Manufacturer
