Proportional Directional Valve 4WRKE16W8-150P-3X/6EG24ETK31/A1D3V - Bosch Rexroth R901524805

Between an axis at 100 l/min and one at 220 l/min there is often a sizing gap. The 4WRKE16W8-150P-3X/6EG24ETK31/A1D3V fills it with 150 l/min nominal flow in size 16, spool symbol W8 and pilot oil routed entirely internally.

Key benefits

• 150 l/min nominal flow in size 16, maximum flow 460 l/min.
• Linear characteristic curve with fine control range, plus internal spool position feedback.
• Pilot supply and pilot return internal, the subplate manages without pilot drillings.
• Spool symbol W8, 3 switching positions, 4 ports, connection pattern ISO 4401-07-07-0-05.
• Plus minus 10 V command into the on-board electronics, 24 VDC supply, up to 350 bar.
• 11.2 kg weight, FKM seals, HL hydraulic fluid, 7-pole connector (6 + PE).

Applications

The valve controls feed, lifting and infeed axes on machine tools, presses and test rigs of medium size. The fine control range of the curve helps with an accurate approach after a rapid stroke. Because pilot oil runs internally, the valve station stays compact.
