Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9K31/A1V - Bosch Rexroth R901092270

Anyone extending an existing axis control wants to keep using the analogue card already installed. The 4WRZE10W6-85-7X/6EG24N9K31/A1V accepts its plus/minus 10 V voltage command directly and meters 85 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• Plus/minus 10 V command value fed straight from the analogue card to the on-board electronics.
• 85 l/min nominal flow, up to 170 l/min maximum flow, operating pressure up to 315 bar.
• External pilot oil supply and external return, the pilot stage does not depend on main pressure.
• Build without a pressure reducing valve, so the pilot stage carries few parts.
• Spool symbol W6, three switching positions on four ports, ISO 4401-05-05-0-05.
• 8.02 kg, FKM seals, 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity.

Application

The valve extends existing axes in presses, test rigs and handling systems that run a central pilot oil supply. That external pilot circuit has to carry pressure continuously, even when the main circuit is unloaded. FKM seals cover the hydraulic fluids released by the manufacturer.
