Proportional Directional Valve 4WRZE10W9-85-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900972615

In a retrofit the manifold usually stays and only the valve is swapped. The 4WRZE10W9-85-7X fits that situation: ISO 4401-05-05-0-05 pattern, 85 l/min nominal flow, a plus or minus 10 V command and pilot oil fed and drained internally.

Benefits

• 85 l/min nominal flow at operating pressures to 315 bar in size 10.
• Fully internal pilot oil routing, so the manifold only needs the four working ports.
• Plus or minus 10 V command into on-board electronics, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Pressure reducing valve in the pilot circuit, spool symbol W9, three switching positions.
• Weight 8.47 kg, NBR seals, hydraulic fluid class HL, UKCA conformity.

Technical data

Applications

Machine builders use this build for feed, lift and clamping axes. A nominal flow of 85 l/min moves medium cylinders briskly yet still allows fine moves in the part-load range. Concealed auxiliary actuation remains reachable for setup work.
