Proportional Directional Valve 4WRKE25W8-220L-3X/6EG24TK31/F1D3M - Bosch Rexroth R901466455

Between 100 and 500 l/min lies the range where size 25 is needed. The 4WRKE25W8-220L-3X/6EG24TK31/F1D3M carries 220 l/min nominal flow there with spool symbol W8, corrects spool position internally and keeps its characteristic linear across the whole command range, at up to 350 bar.

Benefits

• Spool symbol W8 with 3 switching positions and 220 l/min nominal flow in size 25.
• Spool travel is measured inside the valve and fed back, and the characteristic curve is linear.
• Pilot oil arrives externally through the X port and returns internally, operating pressure reaches 350 bar.
• On-board electronics with a 4...20 mA command input, supply 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-08-08-0-05, NBR seals for HL fluid, maximum flow 870 l/min, weight 17.96 kg.

Applications

The valve is fitted in presses, injection moulding machines and test rigs with medium to large bore cylinders. The external pilot supply keeps control alive during phases of low working pressure. The 4...20 mA current command stays stable over long cable runs and makes a broken wire detectable.
