Proportional Directional Valve 4WRZ10W8-85-7X/6EG24N9ETK4/D3M - Bosch Rexroth R900962711

A replacement valve has to match the existing interface, otherwise a swap turns into a rebuild. The 4WRZ10W8-85-7X/6EG24N9ETK4/D3M uses the standard size 10 pattern ISO 4401-05-05-0-05 and controls 85 l/min nominal flow.

Benefits

• Subplate mounting ISO 4401-05-05-0-05, fits existing size 10 manifolds.
• 85 l/min nominal flow, up to 170 l/min flow at 315 bar.
• Internal pilot oil supply and internal return, no additional lines when swapping.
• Spool symbol W8 with 3 switching positions across 4 ports.
• 8.2 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.

Applications

The typical case is replacing an existing proportional valve in size 10 without touching the piping. Internal pilot routing saves cutting additional ports into the manifold. The amplifier in the cabinet usually stays as it is, since the plug follows EN 175201-804.
