4WEMM6J60/AW220N9Z5L

Drop-in replacement for Bosch Rexroth 4WEMM6 series manual valves, ISO 4401-03 mounting.

Model 4WEMM6J60/AW220N9Z5L performs the manual directional control valve role in hydraulic circuits and is built as a direct, dimensionally identical replacement for the corresponding Rexroth 4WEMM original. Set-point and porting behavior follow the original specification, so the valve drops into the existing manifold or line without re-engineering. Bodies are CNC-machined from high-grade cast iron to +/- 0.005 mm, with hardened internal components for long service.

4WEMM6J60/AW220N9Z5L matches the original mounting interface (ISO 4401 subplate, CETOP, or the Shanghai/Chinese standard H10B / H20B pattern for 24*/34* series) with identical bolt spacing and port positions. Solenoid-operated variants use a DIN 43650 connector rated IP65, with coil voltages DC 24 V and AC 220 V. Rated pressure is 31.5 MPa with max flow 80 L/min; fluid compatibility covers mineral oil HL/HLP per DIN 51524, and optional Viton seals are available for special fluids.

Every 4WEMM6J60/AW220N9Z5L unit is 100% factory-tested (electrical where applicable, leakage and peak pressure) with batch-archived records, holds Intertek certification, and is covered by a 1-year replacement warranty with an 8-year design service life. Standard orders ship within 7 working days from Ningbo Port with a 1-piece MOQ; OEM/ODM private labeling and customer-specified set points are available on request.

4WEMM6J60/AW220N9Z5L serves machine tools, hydraulic power units, injection molding and general industrial hydraulics - wherever the system needs stable pressure control, directional logic or flow throttling. For a fast replacement, send the original model code and set-point details to our engineers; a cross-reference confirmation and quotation are provided within 24 hours, free of charge.
