Proportional Directional Valve 4WRKE27E1-500L-3X/6EG24K31/A1D3V - Bosch Rexroth R901079320

In plants with their own pilot pump and established analogue control, a valve swap usually leaves everything else in place. The 4WRKE27E1-500L-3X/6EG24K31/A1D3V slots into that situation with 500 l/min nominal flow, spool symbol E1, a plus or minus 10 V command and a pilot circuit supplied and relieved from outside, at up to 270 bar.

Benefits

• A plus or minus 10 V command and a 7-pole connector (6 + PE) to EN 175201-804 match existing wiring.
• External pilot oil supply and external return suit power units with a separate pilot pump.
• 500 l/min nominal flow with a linear curve and the fine control range of spool symbol E1.
• Internal spool position feedback keeps flow constant through load changes up to 270 bar.
• FKM seals, mounting pattern ISO 4401-08-08-0-05, weight 19.35 kg.

Applications

The valve serves presses, forging hammers and hoists with a separate pilot circuit. Since mounting pattern, signal level and connector shape stay the same, a replacement remains a mechanical job. Range maximum flow reaches 1000 l/min.
