Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R900703118

Less piping plus an interference-proof signal, that is the combination of internal pilot oil routing and a 4...20 mA command value. The W6 spool handles 220 l/min nominal flow, and up to 870 l/min can pass through the valve.

Benefits

• Pilot oil supply and return both internal, which removes two fittings from the manifold
• Command value 4...20 mA, a broken line shows up immediately as missing current
• Nominal flow 220 l/min at operating pressures to 350 bar
• On-board electronics, 24 VDC supply through a 7-pole (6 + PE) connector
• Three switching positions and four ports to ISO 4401-08-08-0-05
• Weight 20.66 kg, NBR seals, HL hydraulic fluid

Application

The variant fits machine tools, hydraulic presses and test rigs with enclosed manifolds. With both pilot paths running internally the number of potential leak points stays low. A concealed auxiliary actuation moves the axis without electrical command.
