Product Detail

Product Description: Control Valve Assembly 803000133 for XCMG QY50B Truck Crane

The 803000133 Control Valve is a genuine XCMG OEM hydraulic component engineered for the hydraulic pilot control system of the XCMG QY50B Truck Crane, a 50‑ton class mobile crane widely used in construction, infrastructure projects, port logistics and industrial material handling. This valve belongs to the 25EY-D6L series of solenoid valves, which are factory‑specified for XCMG K‑Series truck cranes, serving as a critical pilot‑stage element within the crane‘s main hydraulic control system. By directing pilot oil to the main control valve spools in response to operator joystick commands, the solenoid control valve enables precise, low‑effort proportional control of the crane’s primary functions: boom telescoping, boom luffing, main winch hoisting, auxiliary winch hoisting, and slewing rotation.
