The XCMG PN 803069206 corresponds to RPE3-06-3H11/02700E1, a solenoid-operated directional control valve in XCMG paver hydraulic systems — public-channel fitment data lists it under paver spares. The valve body is originally an ARGO-HYTOS product from the RPE3-06 series — NG6 / D03 size, conforming to ISO 4401 / CETOP 03 subplate-mount interface, configured as a 3-position 4-way directional valve. The suffix decodes as: 3H11 where "3" = 3-position, "H" = H-type center function (exact port states at neutral must be confirmed against the ARGO-HYTOS datasheet/drawing), "11" = spool/function variant; 02700E1 = 27V DC coil / 1.07A, with E1 meaning the connector integrates a freewheel (quench) diodeto absorb the reverse EMF spike at de-energization and protect the PLC output and relays. The ARGO-HYTOS spec sheet gives body parameters of max flow 80 L/min, max pressure 350 bar, a five-chamber housing design to reduce fluid-viscosity dependence, and a coil that rotates 360° to suit the available space. 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.
