Proportional Directional Valve 4WRTE10V100P-4X/6EG24ETK31/A1M - Bosch Rexroth R901389124

When an axis has to travel fast and still position finely, one valve has to do both. The 4WRTE10V100P-4X/6EG24ETK31/A1M carries 100 l/min nominal flow in size 10, corrects spool position internally and keeps its fine control range in the lower command band, at up to 350 bar.

Benefits

• 100 l/min nominal flow with spool symbol V, 4 ports and 3 switching positions.
• Pilot oil supply and return both run inside the valve, which saves two external control lines.
• An internal position transducer reports spool position to the control loop, and the characteristic curve is linear with a pronounced fine control range. Operating pressure reaches 350 bar.
• The ±10 V command value feeds the on-board electronics directly, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Hole pattern ISO 4401-05-05-0-05 to ISO 4401, NBR seals for HL fluid, 170 l/min maximum flow at 9.5 kg.

Applications

It pays off on axes with a long rapid stroke and a short fine stroke, for example drawing presses, bending machines and test cylinders. The internal pilot stage saves X and Y lines in the manifold. At 9.5 kg the valve stays within the usual weight class of size 10.
