Proportional Directional Valve 4WRKE25W8-350P-3X/6EG24TK31/A1D3M - Bosch Rexroth R901115913

When working pressure drops during the pressing cycle, an internally fed pilot stage also loses actuating speed. This size 25 valve therefore takes its pilot oil externally from a regulated source and drains it internally, while metering 350 l/min nominal flow with a fine control range.

Benefits

• External pilot oil supply with internal pilot oil return for a constant actuating speed
• 350 l/min nominal flow, up to 870 l/min across the valve
• ±10 V command value, 24 VDC supply, on-board electronics
• Spool symbol W8, linear characteristic curve with a fine control range
• NBR seals, operating pressure up to 350 bar, weight 17.82 kg

Technical data

Applications

Applications are presses and forming lines whose system pressure swings sharply during the cycle. The X port is connected to the regulated pilot source while the pilot drain stays internal. The manifold follows the ISO 4401-08-08-0-05 port pattern.
