Proportional Directional Valve 4WRTE10V50P-4X/6EG24EK31/A1M - Bosch Rexroth R900738737

When a machine return line carries pressure, the pilot stage needs its own path to tank. The 4WRTE10V50P-4X/6EG24EK31/A1M takes control oil internally, drains it through Y and so meters 50 l/min nominal flow with spool symbol V and internal position feedback at up to 350 bar.

Benefits

• 3 switching positions and 4 ports at 50 l/min nominal flow, spool symbol V.
• Pilot oil is taken internally and drained externally through the Y port.
• 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 8.44 kg.

Applications

The valve is fitted on grinding and honing machines, tracking axes and smaller test cylinders with return filtration. The fine control range allows very low speeds without stick slip taking hold. The subplate has to provide the Y port in addition.
