Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R900776501

The 4WRZE10W6-85-7X/6EG24N9EK31/A1D3M links the high nominal flow of 85 l/min with the +/-10 V voltage command value. Internal pilot supply saves the X line, while external draining through Y keeps pilot pressure clean. The spool carries symbol W6 and operating pressure reaches 315 bar.

Benefits

• 85 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• Internal supply from port P, external draining through Y.
• Command value +/-10 V, on-board electronics with position feedback, 24 VDC supply.
• Concealed auxiliary actuation for movement without control voltage.
• Spool symbol W6, 3 switching positions, 4 ports, ISO 4401-05-05-0-05.
• Weight 8.45 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

This version fits fast axes in plants with a shared return line, for instance presses with several consumers. External pilot draining decouples the pilot stage from back pressure. Permanent pressure in port P is a precondition.
