Proportional Directional Valve 4WRTE25V220L-4X/6EG24EK31/F1M - Bosch Rexroth R901515692

Positioning accuracy comes from a valve that knows its own spool position. The internal position feedback in this valve measures spool travel and corrects it, so 220 l/min nominal flow is released linearly and repeatably.

Benefits

• Internal spool position feedback for high control accuracy and low hysteresis
• Linear relationship between command value and flow, nominal flow 220 l/min
• Command value 4...20 mA, immune to interference over long cable runs
• Operating pressure 350 bar, up to 870 l/min through the valve
• Internal pilot oil supply with external return, only one extra line needed
• Weight 17.92 kg, port pattern ISO 4401-08-08-0-05

Application

The 4WRTE series is used wherever position or force is closed-loop controlled, for example in testing machines, roll gap adjustment and servo presses. The on-board electronics handle position control and output stage inside the valve. Operation is on HL hydraulic fluid with NBR seals at 24 VDC.
