Proportional Directional Valve 4WRKE25E1-350P-3X/6EG24K31/A1D3V - Bosch Rexroth R900617637

At size 25 the question is whether the curve around mid position stays fine enough. This pilot-operated model carries a fine control range for that, converts 350 l/min nominal flow and runs on an external pilot oil supply at operating pressure up to 350 bar.

Benefits

• 350 l/min nominal flow against 870 l/min maximum flow, reserve for rapid traverse plus return stroke.
• Linear curve with a fine control range keeps the axis steerable even at small command values.
• External pilot oil supply with external return, independent of working pressure.
• On-board electronics on a ±10 V command value, supply 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-08-08-0-05, spool symbol E1, FKM seals, mass 17.82 kg.

Applications

The valve is fitted in large presses, forging plants and lifting gear with high oil demand. Its 3 switching positions on symbol E1 provide the mid position of the schematic. Operation is intended with hydraulic fluid of class HL.
