Proportional Directional Valve 4WRTE10W8-100L-4X/6EG24EK31/F1V - Bosch Rexroth R901293887

In plants with warm oil and a pressurised return, a control valve has to cope with both. The 4WRTE10W8-100L-4X/6EG24EK31/F1V therefore carries FKM seals, drains its pilot stage separately through Y and meters 100 l/min nominal flow on a linear characteristic at up to 350 bar.

Benefits

• The spool carries symbol W8 and the nominal flow is 100 l/min.
• Internal pilot oil supply with external drain through Y, so tank pressure does not act on the pilot stage.
• Piston travel is measured inside the valve and fed back, and the characteristic curve is linear. Operating pressure reaches 350 bar.
• On-board electronics process the 4...20 mA command value at the valve, powered by 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-05-05-0-05, FKM seals for HL fluid, maximum flow 170 l/min, weight 8.44 kg.

Applications

Valves like this work on die casting machines, hot forming presses and endurance test rigs. The separate Y drain keeps return pressure away from the pilot stage, and the linear characteristic eases controller design. Internal spool feedback gives repeatable positions.
