Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9ETK31/A1M - Bosch Rexroth R901285342

The spool decides how the axis behaves, the pilot oil routing decides how reliable it is. The 4WRZE25W6-220-7X/6EG24N9ETK31/A1M combines symbol W6 with external supply and external drain and meters 220 l/min nominal flow at 350 bar operating pressure.

Benefits

• Spool symbol W6 across three switching positions and four ports.
• 220 l/min nominal flow and up to 870 l/min maximum flow in size 25.
• External pilot oil supply and external pilot oil drain make the pilot stage independent of the main circuit.
• A ±10 V command value at the on-board electronics, 24 VDC supply.
• 350 bar operating pressure, NBR seals, 20.14 kg valve mass, ISO 4401-08-08-0-05 mounting pattern.

Application

Intended for plants where the axis needs a particular spool characteristic and the pressure conditions in the circuit change. Two pilot oil lines have to be laid in addition. Presses, test rigs and forming lines are the typical locations.
