Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9EK31/F1D3V - Bosch Rexroth R978914695

Two disturbances act on an internally piloted stage: varying system pressure at the inlet and back pressure at the drain. The 4WRZE25E1-325-7X/6EG24N9EK31/F1D3V answers both, with a built-in pressure reducing valve and an external pilot drain, at 325 l/min nominal flow.

Benefits

• Pressure reducing valve at the inlet and an external drain decouple the pilot stage completely.
• 325 l/min nominal flow, maximum flow 870 l/min, size 25.
• 4...20 mA command value on 24 VDC, spool symbol E1, 3 switching positions.
• Concealed manual override, operating pressure up to 350 bar.
• FKM seals, ISO 4401-08-08-0-05 interface, 20.58 kg, UKCA conformity.

Applications

This version belongs in plant with strongly varying system pressure and a loaded return, for example forming presses and multi-axis test rigs. Only one extra line to tank has to be laid, a pilot pump is not needed. The current setpoint allows long signal runs.
