Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900712725

A fine return filter costs pressure, and that back pressure shifts the pilot null position. The 4WRZE10W8-50-7X/6EG24N9EK31/A1D3V avoids it through an external pilot drain on internal supply, at 50 l/min and 315 bar.

Benefits

• External pilot drain - filter back pressure in the main return no longer affects control.
• Internal pilot oil supply, so only one extra line to route.
• 50 l/min nominal flow, 170 l/min maximum throughput, 315 bar operating pressure.
• ±10 V setpoint, on-board electronics, 24 VDC supply.
• Mass 8.46 kg, spool symbol W8, FKM seals, ISO 4401-05-05-0-05 interface.

Applications

Suits plants using fine return filtration, machine tools held to high cleanliness levels, and long return runs to a remote tank. The separate drain should reach tank without back pressure.
