Proportional Directional Valve 4WRTE32E1-400L-4X/6EG24K31/A1M - Bosch Rexroth R900244404

When an older axis is modernised, usually everything except the valve stays in place. The 4WRTE32E1-400L-4X/6EG24K31/A1M slots into that situation: spool symbol E1, 400 l/min nominal flow, a plus or minus 10 V command and a pilot circuit supplied from outside and relieved to the outside, at operating pressures up to 350 bar.

Benefits

• 400 l/min nominal flow in size 32 against a range maximum flow of 1600 l/min.
• Spool symbol E1 with 3 switching positions preserves the mid position function of the existing schematic.
• External pilot oil supply and external return suit power units with a separate pilot pump.
• Plus or minus 10 V input, powered by 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-10-09-0-05, weight 37.22 kg, NBR seals for mineral oil of class HL.

Applications

The valve works in medium presses, lift tables and clamping systems in machine tool building. With nominal flow at 400 l/min, control stays fine enough in the part-load range for smooth motion. The pilot circuit is routed separately and therefore stays independent of working pressure.
