Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9K31/F1D3M - Bosch Rexroth R900764345

When the control cabinet sits far from the machine, a voltage command value picks up interference on the way. This valve therefore works with a 4...20 mA command value and meters 220 l/min nominal flow at operating pressures to 350 bar.

Benefits

• A 4...20 mA command value stays immune to interference over long cable runs and signals a broken wire at zero current
• Nominal flow 220 l/min, up to 870 l/min through the valve
• External pilot oil supply and external return separate the pilot circuit fully from the main circuit
• Operating pressure to 350 bar with three switching positions and four ports
• W6 spool on port pattern ISO 4401-08-08-0-05
• 24 VDC supply through a 7-pole (6 + PE) connector to EN 175201-804

Application

The version suits sprawling installations such as locks, forging presses and test fields where cabinet and power unit are far apart. A fully external pilot circuit can be filtered and pressure-protected on its own. The valve weighs 20.68 kg and is sealed with NBR.
