Proportional Directional Valve 4WRZE10E1-50-7X/6EG24N9K31/F1M - Bosch Rexroth R901483876

A centrally fed pilot circuit supplies pilot oil and takes it back again, so the directional valve needs no pressure reducing valve of its own. The 4WRZE10E1-50-7X/6EG24N9K31/F1M is built exactly that way, works with spool symbol E1 and regulates 50 l/min nominal flow from a 4...20 mA current command.

Benefits

• External pilot oil supply and external return, version without pressure reducing valve.
• Spool symbol E1 with three switching positions and 50 l/min nominal flow.
• Concealed auxiliary actuation for commissioning and fault finding.
• Operating pressure up to 315 bar, maximum flow 170 l/min, size 10.
• Current command 4...20 mA on on-board electronics, 24 VDC, weight 8.06 kg.

Applications

Steelworks, press lines and test fields with a central pilot oil station use exactly this variant. Because pilot oil arrives from outside, the pilot pressure survives a brief collapse of the working pressure. Connection diagram ISO 4401-05-05-0-05 of size 10 remains unchanged.
