Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901088213

In metallurgical plants the pilot stage often runs on its own filtered circuit. The 4WRZE25E1-325-7X/6EG24N9K31/F1D3M takes pilot oil from outside and drains it outside while metering 325 l/min nominal flow at 350 bar operating pressure.

Benefits

• Pilot oil supply and return both external, matching separated control oil circuits.
• Nominal flow 325 l/min, plant flow up to 870 l/min in size 25.
• A 4 to 20 mA current command bridges long distances to the control room.
• Spool symbol E1 with 3 switching positions, connection diagram ISO 4401-08-08-0-05, 4 ports.
• Operating pressure 350 bar, weight 20.68 kg, UKCA conformity to SI2016/1091.

Applications

The valve adjusts moulds, oscillation drives and roll settings in casting and rolling plants. The dedicated pilot circuit keeps the pilot stage clean even when the working circuit is heavily loaded. A subplate to ISO 4401-08-08-0-05 is enough for mounting.
