Proportional Directional Valve 4WRPF6E18SJ-3X/M00/24ND90 - Bosch Rexroth R901575530

On short feed movements the resolution at low flow decides how smooth the motion looks. That is why the 4WRPF6E18SJ-3X/M00/24ND90 is rated at 18 l/min nominal flow while still releasing up to 82 l/min when needed, with PROFINET RT linking it straight to the controller.

Benefits

• 18 l/min nominal flow gives finer resolution than a larger rating in the same size 6 body.
• Up to 82 l/min maximum flow stays in reserve for rapid traverse and return strokes.
• PROFINET RT carries command value and diagnostics on one bus cable, with the electronics built into the valve.
• Spool symbol E, three switching positions, four ports, ISO 4401-03-02-0-05 mounting pattern.
• 350 bar operating pressure at 4.2 kg valve mass, NBR seals for HL hydraulic fluid.

Application

Intended for positioning and feed axes with modest volume demand, for example on test and assembly equipment. The low nominal rating pays off when an axis has to travel slowly and evenly. Faster strokes still have the 82 l/min reserve.
