Wegeventil 4WRLD25V1-400P-4X/MXY/24ND6T - Bosch Rexroth R901569538

When position control runs in the PLC, every bus cycle costs response time. This size 25 version of the 4WRLD carries an integrated digital axis controller and closes the loop at the valve. The 12-pole connector brings in the command value and the signals, and the valve controls 400 l/min nominal flow, up to 1250 l/min.

Benefits

• Integrated digital axis controller on the valve, the control loop is closed locally
• 400 l/min nominal flow and 1250 l/min maximum flow on connection diagram ISO 4401-08-08-0-05
• Connector, 12-pole (11 + PE) to EN 175201-804 for command value, supply and feedback signals
• Linear characteristic with fine control range, spool symbol V1, internal piston position feedback
• External pilot oil supply and external pilot oil return, analog command value ±10 V at 24 VDC
• NBR seals for hydraulic fluid HL, operating pressure up to 350 bar, weight 18.9 kg

Applications

Valves with an integrated axis controller run in presses, test cylinders, swivel drives and simulators where an axis has to follow a path and keep response times short.

Because controller and valve form one unit, the amplifier card in the cabinet is no longer required and wiring comes down to one cable at the 12-pole connector. External pilot oil supply secures the pilot pressure even when the main circuit drops during start-up. The UKCA declaration on electromagnetic compatibility is available.

Manufacturer

Bosch Rexroth lists the valve under material number R901569538. The type code 4WRLD25V1-400P-4X/MXY/24ND6T states the size, the spool symbol, the nominal flow and the electronics version.
