Proportional Directional Valve 4WRZ25W8-325-7X/6EG24N9K4/D3V - Bosch Rexroth R900950967

A pilot-operated axis runs only as cleanly as its pilot oil circuit. The 4WRZ25W8-325-7X/6EG24N9K4/D3V draws pilot oil from an external source and returns it through a dedicated line, while the main channel carries 325 l/min nominal flow.

Advantages

• 325 l/min nominal flow, peaks to 870 l/min in the main channel of size 25.
• Pilot oil supplied and drained externally, with a pressure reducing stage in the pilot circuit.
• Spool symbol W8 with three switching positions, plus concealed auxiliary actuation for setup work.
• ISO 4401-08-08-0-05 pattern, size 25, rated up to 350 bar operating pressure.
• Connector, 3-pole (2 + PE) for the electrical link, 24 VDC supply.
• 20.42 kg mass, FKM seals, HL grade fluid.

Applications

The unit meters advance and return on presses, stretching lines and forging machines built in size 25. An external pilot circuit can be supplied and filtered centrally, which is common where several pilot-operated units share one machine. Replacement works on any ISO 4401-08-08-0-05 hole pattern.
