Proportional Directional Valve 4WRTE10V50P-4X/6EG24ETK31/A1M - Bosch Rexroth R901477856

An axis hits its target only as precisely as the valve spool knows its own position. The 4WRTE10V50P-4X/6EG24ETK31/A1M measures spool travel inside the valve and corrects it, metering 50 l/min nominal flow with spool symbol V at operating pressures up to 350 bar.

Benefits

• Spool symbol V with 3 switching positions and 50 l/min nominal flow in size 10.
• Pilot oil is taken internally and returned internally, so no separate X and Y line is needed.
• Piston travel is measured inside the valve and fed back, and the characteristic curve is linear with a pronounced fine control range. Operating pressure reaches 350 bar.
• On-board electronics process the ±10 V 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, NBR seals for HL fluid, maximum flow 170 l/min, weight 8.46 kg.

Applications

The fine control range of symbol V shows itself when approaching end positions slowly, for example on grinding feeds, tracking axes and materials testing machines. With pilot supply and return running internally, a standard subplate is all that is required. The electronics sit directly on the valve.
