Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9EK31/A1M - Bosch Rexroth R901046275

Pilot oil from the main channel, drain through a line of its own: this combination saves the X line and still keeps the pilot stage clear of back pressure in the tank line. The valve carries 325 l/min with spool symbol E1 and follows a plus/minus 10 V command.

Benefits

• Internal supply with external drain Y, a compromise between little plumbing and a clean null position.
• Plus/minus 10 V command straight from the axis controller, no signal converter needed.
• Nominal flow 325 l/min, maximum 870 l/min, operating pressure 350 bar.
• Spool symbol E1, three switching positions, concealed auxiliary actuation.
• On-board electronics on 24 VDC through a 7-pole connector (6 + PE), mass 20.22 kg.

Applications

The layout fits manifolds whose tank channel is pressurised by other valves while no separate control circuit exists. Situations like that arise in press plants that have grown over time and in test rigs with many consumers. The Y line is routed separately and without pressure to tank.
