Proportional Directional Valve 4WRTE27E1-500L-4X/6EG24K31/A1M - Bosch Rexroth R901016732

Where the manifold already provides a separate pilot circuit, a valve with external pilot oil supply and external pilot oil return fits the layout. The 4WRTE27E1-500L-4X/6EG24K31/A1M meters a nominal flow of 500 l/min in size 27, guides the spool through on-board electronics with position feedback and takes the command value as a ±10 V voltage.

Benefits

• Nominal flow 500 l/min, maximum flow 1000 l/min at a maximum operating pressure of 270 bar.
• External pilot oil supply and external pilot oil return keep the pilot stage separate from the axis pressure.
• On-board electronics with internal spool position feedback, analog command value ±10 V on a 24 VDC supply.
• Spool symbol E1 with three switching positions across four ports and a linear characteristic.
• Subplate mounting to ISO 4401-08-07-0-05, NBR seals for HL hydraulic fluid, weight 19.32 kg.

Applications

Typical mounting places are the main axes of presses, stretching lines and testing machines that run position or velocity control. The separate pilot circuit keeps the pilot stage steady even when the working pressure at the axis swings widely. The ±10 V voltage command connects straight to analog axis controllers without an extra amplifier card.
