Proportional Directional Valve 4WRDE10V1-50L-6X/MXY/24A5-280 - Bosch Rexroth R901556121

Older and special control cards issue their command as a bipolar current signal. The 4WRDE10V1-50L-6X/MXY/24A5-280 is built for them with a ±10 mA command input, at 50 l/min nominal flow and 350 bar operating pressure.

Benefits

• ±10 mA command instead of the usual voltage interface, matching bipolar current outputs.
• 50 l/min nominal flow for fine movements, maximum flow up to 170 l/min.
• External pilot oil supply and external return let the pilot circuit work independently of the main circuit.
• Spool symbol V1 with a linear characteristic, 3 switching positions on 4 ports.
• 7.5 kg valve mass, NBR seals, mounting pattern ISO 4401-05-05-0-05, 24 VDC supply.

Applications

Intended as a replacement in existing installations whose amplifier or controller card supplies a ±10 mA current command. No electronics conversion is needed. For new systems with a voltage output, the same size exists with a ±10 V command.
