Proportional Directional Valve 4WRZE25E325-7X/6EG24N9K31/F1D3M - Bosch Rexroth R900755370

A self-contained pilot circuit only works when pilot oil supply and return run outside the valve. This build with spool symbol E routes both externally and meters 325 l/min nominal flow at an operating pressure up to 350 bar.

Benefits

• External pilot oil supply and external pilot oil return, so pilot pressure is set independently of the main circuit.
• Nominal flow 325 l/min, with up to 870 l/min flow possible through the valve.
• Spool symbol E with three switching positions and four ports.
• Operating pressure up to 350 bar, weight 20.44 kg.
• Command value 4...20 mA at the on-board electronics, supply 24 VDC through a 7-pole (6 + PE) connector.
• Port pattern ISO 4401-08-08-0-05 for size 25 subplate mounting.

Applications

The variant runs on test rigs, in press hydraulics and on drives with large cylinder volumes. The externally fed pilot circuit can carry its own pressure, for example from a control circuit with a separate pump. Sealing is NBR for HL hydraulic fluid.
