Proportional Directional Valve 4WRZE10E1-50-7X/6EG24N9TK31/A1D3V - Bosch Rexroth R900932675

A load change makes system pressure dip briefly, and internally supplied piloting then responds sluggishly. The 4WRZE10E1-50-7X/6EG24N9TK31/A1D3V therefore takes control oil externally, for example from an accumulator, and keeps metering 50 l/min at up to 315 bar.

Benefits

• External pilot oil supply - pilot pressure survives a dip in main pressure.
• Internal pilot drain, so only one extra line instead of two.
• 50 l/min nominal flow, 170 l/min maximum throughput, 315 bar operating pressure.
• ±10 V setpoint into on-board electronics, 24 VDC supply.
• Mass 9.46 kg, spool symbol E1, ISO 4401-05-05-0-05 interface, FKM seals.

Applications

Matches presses with pronounced load steps, forging plant, and axes fed from an accumulator. Where main pressure stays stable, an internally supplied version of the same series is enough.
