Proportional Directional Valve 4WRLE25Q3-400M-4X/MXY/24A1 - Bosch Rexroth R901504916

Axes that must start slowly and then travel fast benefit from a progressive characteristic. The 4WRLE25Q3-400M-4X/MXY/24A1 offers exactly that, with a linear fine control range around zero, 400 l/min rated flow and 350 bar operating pressure.

Benefits

• Progressive curve with a linear fine control range, small command values produce fine motion.
• Spool symbol Q3 with 3 switching positions and internal spool position feedback.
• 400 l/min rated flow, 1250 l/min maximum flow in size 25.
• External pilot oil supply plus external pilot return through X and Y.
• CE marked, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804, 18.73 kg.

Applications

The valve suits positioning axes on forming machines, slewing gear and test cylinders with slow force build-up. Inside the fine control range the gain stays constant, so the position controller needs no gain switching. Beyond that range the spool opens progressively up to full flow.
