The XCMG PN 803069204 corresponds to RPE3-06-3Y11/02700E1, a solenoid-operated directional control valve in XCMG paver hydraulic systems — originally an ARGO-HYTOS product, NG6 / D03 size, ISO 4401 / CETOP 03 footprint, 3-position 4-way configuration. The suffix decodes as: 3Y11 = 3-position, 4-way, "Y" center condition (P blocked, A/B open to tank T in neutral); 02700E1 = 27V DC coil / 1.07A, with E1 meaning the connector integrates a freewheel (quench) diode to absorb the reverse EMF spike at de-energization and protect the PLC output and relays. Public-channel fitment data covers pavers: RP803, RP953, RP953E, RP953T, RP1253, RP1356; XCMG parts catalogs list it under paver spares and mark it as a wear part. Operating principle: the energized coil generates a magnetic field that pushes the spool against the return spring, switching the P/A/B/T port connections to direct the actuator; when de-energized, the spring returns the spool to center.
