Proportional Directional Valve 4WRZ25W8-325-7X/6EG24N9ETK4/D3V - Bosch Rexroth R900945912

Two lines fewer on the manifold and in the cabinet: the 4WRZ25W8-325-7X/6EG24N9ETK4/D3V feeds and relieves its pilot stage internally. The main channel carries 325 l/min nominal flow, the ISO 4401-08-08-0-05 hole pattern stays unchanged.

Advantages

• Pilot oil fed and drained internally, neither a pilot pump nor a separate drain line is needed.
• 325 l/min nominal flow, 870 l/min limit at 350 bar operating pressure.
• 20.3 kg mass, spool symbol W8, three switching positions and concealed auxiliary actuation.
• 350 bar operating pressure on connection diagram ISO 4401-08-08-0-05 of size 25.
• 24 VDC supply, wiring per Connector, 7-pole (6 + PE) according to EN 175201-804.
• HL grade fluid with FKM seals, 20.3 kg mass.

Applications

The variant suits compact control manifolds where every extra bore costs space. It requires a tank port with low back pressure, because the pilot drain joins in there. In existing plant it replaces identical units of the same pilot variant.
