Proportional Directional Valve 4WRZE10W8-50-7X/6EG24K31/A1D3M - Bosch Rexroth R983031570

For a size 10 axis in the middle flow range, the 4WRZE10W8-50-7X/6EG24K31/A1D3M offers 50 l/min nominal flow at an operating pressure of up to 315 bar. The pilot stage is fed by a built-in pressure reducing valve, while pilot oil supply and return both run externally. The +/-10 V command value drives the spool of symbol W8.

Benefits

• 50 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• Built-in pressure reducing valve in the pilot stage keeps pilot pressure independent of load pressure.
• External pilot oil supply and external return suit circuits with their own pilot pressure source.
• Command value +/-10 V, on-board electronics, 24 VDC supply.
• Spool symbol W8, 3 switching positions, 4 ports, mounting pattern ISO 4401-05-05-0-05.
• Weight 8.48 kg, UKCA conformity, NBR seals for hydraulic fluid HL.

Application

The valve fits machine tools, plastics machinery and test rigs in which a medium axis is moved steplessly. External pilot routing requires a separate pilot circuit using ports X and Y. A size 10 subplate is enough for mounting.
