Proportional Directional Valve 4WRZE10E85-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901005622

Where long cable runs separate the cabinet from the valve, a current command is less prone to interference than a voltage. The 4WRZE10E85-7X/6EG24ETK31/F1D3M therefore uses the 4...20 mA interface, carries 85 l/min nominal flow at up to 315 bar operating pressure and keeps both pilot oil supply and return inside the valve.

Benefits

• Command input 4...20 mA, insensitive to voltage drop along long cables.
• Nominal flow 85 l/min, maximum flow 170 l/min in size 10.
• Internal pilot oil supply and internal pilot oil return, separate pilot lines are not needed.
• Operating pressure up to 315 bar across four ports to ISO 4401-05-05-0-05.
• Spool symbol E, on-board electronics on 24 VDC, weight 9.05 kg.

Applications

Widely distributed plants such as lock gate drives, steelworks axes and press lines benefit from the current interface. Because both pilot oil paths run inside the valve, pipework is limited to the four working ports. Power arrives through the 7-pole connector to EN 175201-804.
