Proportional Directional Valve 4WRTE25V1-220L-4X/6EG24K31/F1V - Bosch Rexroth R901144221

Between 220 and 350 l/min in the same frame size lies a clear difference in resolution. Choosing the smaller step gives finer control over an axis. The 4WRTE25V1-220L offers exactly that grading.

Benefits

• Spool Symbol V1 with a linear characteristic, 3 switching positions
• External pilot oil supply and external pilot oil return, pilot operated design
• On-board electronics close the position loop themselves, so no separate amplifier is needed in the cabinet
• Command value Analog, command value 4 to 20 mA on a 24 VDC supply, Connector, 7-pole (6 + PE)
• FKM seals matched to HL hydraulic fluid

Applications

The choice fits axes that are large in build but have to travel slowly and precisely, for example on testing machines and positioning hoists. Pilot oil is fed and drained externally, so the pilot stage can be filtered. The valve weighs 18 kg.
