Proportional Directional Valve 4WRTE25V1-220L-4X/6EG24ETK31/F1M - Bosch Rexroth R901154452

Under cyclic load it is repeat accuracy that counts, not a peak figure. The internal position feedback here measures spool travel continuously and corrects it, so every cycle runs at the same 220 l/min nominal flow.

Benefits

• Internal position feedback compensates deviation during the running cycle
• Nominal flow 220 l/min at 350 bar operating pressure, up to 870 l/min through the valve
• Command value 4...20 mA, no zero drift from voltage drop along the cable
• Pilot oil supply and return internal, removing two pilot ports
• V1 spool, three switching positions, four ports
• Weight 17.96 kg on port pattern ISO 4401-08-08-0-05

Application

The valve is intended for fatigue test rigs, cycling presses and plants with high cycle counts. Internal pilot routing keeps piping work low. Operation is on HL hydraulic fluid with NBR seals at a 24 VDC supply.
