Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9K31/F1V - Bosch Rexroth R901035807

On a hydraulic motor the supplied flow decides the speed, and the demand value has to arrive undistorted even in electrically noisy surroundings. The 4WRZE10W6-50-7X/6EG24N9K31/F1V accepts a 4...20 mA current command for that reason and turns it into motor speed and direction at 50 l/min nominal flow. Operating pressure may reach 315 bar, and up to 170 l/min flows for short periods.

Benefits

• 4...20 mA current interface - interference from drives and long cable routes leave the metered flow unaffected.
• 50 l/min nominal flow - matched to motors of medium displacement, with the valve peaking at 170 l/min.
• Spool symbol W6 - 3 switching positions and 4 ports for drives that work in both directions of rotation.
• On-board electronics - no separate amplifier is required, the 24 VDC supply and the command signal arrive through the 7-pole (6 + PE) connector to EN 175201-804.
• External pilot oil supply - control pressure stays steady through load changes at the motor, and pilot oil return is routed externally.
• 8.01 kg on ISO 4401-05-05-0-05 subplate mounting - size 10 with FKM seals, released for HL hydraulic fluid.

Applications

This combination is asked for on winding and reeling drives, rotary tables and test rigs where the controller outputs speed ramps as a current signal. Because the valve fits the standard size 10 mounting pattern, it drops into existing manifolds. A dedicated control oil supply is required for the pilot circuit.
