Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901040911

Reducing pilot pressure inside the manifold means another valve there, extra bores and one more sealing face. This version carries the reducing stage in its own housing and moves 325 l/min with spool symbol W6.

Benefits

• Pressure reducing valve in the pilot line keeps a separate reducing stage out of the manifold.
• Internal supply with external drain Y leaves one control line to the outside.
• Nominal flow 325 l/min, maximum flow 870 l/min, operating pressure up to 350 bar.
• Spool symbol W6 in three switching positions with concealed auxiliary actuation.
• Current command 4...20 mA, on-board electronics on 24 VDC, mass 20.64 kg.

Technical data

Applications

The benefit shows when a new manifold is designed, where every extra bore costs machining time and adds a sealing face. On retrofits it also avoids reworking the existing manifold. The Y line is routed to tank without pressure.
