Proportional Directional Valve 4WRTE25E1-220P-4X/6EG24K31/A1M - Bosch Rexroth R901566706

Where an axis has to approach gently and then hold still, spool position feedback decides the result. The 4WRTE25E1-220P-4X/6EG24K31/A1M measures that internally and provides 220 l/min nominal flow at up to 350 bar, while the range itself reaches 1000 l/min.

Benefits

• Internal spool position feedback holds flow at the command value even when load changes.
• Spool symbol E1 with a fine control range and 3 switching positions, 220 l/min nominal flow.
• The range covers up to 1000 l/min, so this valve works well below its structural limit.
• Plus or minus 10 V command into on-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• External pilot oil supply and external return, mounting pattern ISO 4401-08-08-0-05, 17.7 kg.

Applications

Typical places are infeed axes on rolling mills, test cylinders and die cushions where position and force have to be held at once. The pilot circuit is fed separately, so the valve stays stable even when working pressure fluctuates. NBR seals suit mineral oil of class HL.
