Proportional Directional Valve 4WRTE16W8-220L-4X/6EG24K31/F1M - Bosch Rexroth R901430352

Scrap shears and baling presses combine high flows with long, electrically rough signal routes across the yard. The 4WRTE16W8-220L-4X/6EG24K31/F1M therefore accepts 4...20 mA, is fed from an external pilot circuit and meters 220 l/min nominal flow at up to 350 bar.

Benefits

• 4...20 mA command value, resistant to interference on long outdoor cable runs.
• 220 l/min nominal flow, maximum flow 460 l/min in size 16.
• External pilot oil supply and external pilot oil return.
• Spool symbol W8 with a linear characteristic curve, operating pressure up to 350 bar.
• Connection diagram ISO 4401-07-07-0-05, 11.04 kg weight, NBR seals for HL hydraulic fluid.

Applications

The valve controls closing, pressing and cutting axes in recycling plants as well as feed equipment on processing machinery. An external pilot circuit provides actuating energy regardless of working pressure, even while the main cylinder is pushing into material. At 220 l/min cycle times stay short.
