Proportional Directional Valve 4WRLE25V400L-4X/MXT/24A1 - Bosch Rexroth R901476874

A dedicated pilot pressure makes the pilot stage independent of working pressure and costs only one extra line. The 4WRLE25V400L-4X/MXT/24A1 is fed through X, relieved internally and provides 400 l/min rated flow in size 25.

Benefits

• External pilot supply through X keeps the pilot stage stable even when working pressure collapses.
• Internal pilot return, so no Y line is required.
• 400 l/min rated flow, maximum flow 1250 l/min, operating pressure up to 350 bar.
• Spool symbol V, linear curve, plus minus 10 V command value, 24 VDC supply.
• Mounting pattern ISO 4401-08-08-0-05, CE marked, NBR seals, 19.4 kg.

Applications

The valve is used in presses and lifting gear whose working pressure drops sharply during the cycle, for example in rapid traverse. External pilot supply keeps dynamics constant in those phases. It requires a pilot pressure source with enough volume, often a small accumulator.
