Proportional Directional Valve 4WRKE25R350L-3X/6EG24K31/A1D3M - Bosch Rexroth R901510240

On cylinders with a large bore the available flow decides the cycle time. The 4WRKE25R350L-3X/6EG24K31/A1D3M supplies 350 l/min nominal flow in size 25 for that job, follows a plus or minus 10 V command and is rated to 350 bar operating pressure.

Benefits

• 350 l/min nominal flow in size 25, with the series maximum flow at 870 l/min.
• Spool symbol R with 3 switching positions plus a linear characteristic curve for even signal mapping.
• External pilot oil supply and external return suit power units with a separate pilot pump.
• Plus or minus 10 V command at the on-board electronics, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-08-08-0-05, NBR seals for HL mineral oil, weight 17.9 kg.

Technical data

Applications

The valve works on press main cylinders, on die cushions and on lifting gear in metallurgical plants. Because pilot supply and return are routed separately, pilot control stays independent of working pressure and step response remains predictable under changing load. Spool position is fed back internally.
