Proportional Directional Valve 4WRZE25E1-220-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R901086136

While levelling, the roll setting moves constantly in small steps as the strip is pulled through at full force. The 4WRZE25E1-220-7X/6EG24N9TK31/A1D3M provides 220 l/min nominal flow for that, commanded by ±10 V and fed by an external pilot supply.

Benefits

• A ±10 V command value allows fine correction steps straight from the axis controller.
• External pilot supply with internal return saves a line compared with the fully external version.
• Nominal flow 220 l/min at 350 bar operating pressure, plant maximum 870 l/min.
• Spool symbol E1, 3 switching positions, ISO 4401-08-08-0-05, 4 ports, 20.58 kg.
• On-board electronics at 24 V DC, concealed manual override, UKCA to SI2016/1091.

Applications

The valve serves levellers, strip lines and roll settings in sheet metal processing. Since the pilot stage has its own supply, fine control stays unaffected by load peaks. The NBR sealing suits plants running HL mineral oil.
