Multiway Valve 803000096 XCMG Truck Crane
The Multiway Valve 803000096 (QYZTF-S10E) is a key hydraulic component used in XCMG truck cranes. It is a modular control valve that directs oil flow to different actuators, primarily used for controlling outrigger operations and other hydraulic functions in XCMG crane models .
This valve integrates multiple control functions into a single unit, providing direction control, flow and pressure adjustment, and load sensing capabilities for crane hydraulic systems .
- Direction Control: Shifting the spool position controls the extension, retraction, and luffing of the boom, as well as the lifting and lowering of the hook .
- Flow & Pressure Adjustment: Regulates actuator speed by adjusting the spool opening, and protects the system from overpressure via integrated relief valves .
- Load Sensing: Provides energy-saving features by distributing flow according to actual load demand .
- Integrated & Modular Design: Multiple control units integrated into one valve body, reducing hydraulic system complexity and maintenance costs .

Crawler Crane / Other Models:
The multiway valve plays a vital role in the crane's hydraulic system:
- Direction Control: By changing the position of the spool, the valve controls the flow direction of hydraulic oil, enabling actions such as telescoping, lifting, and slewing of the crane's executive elements .
- Flow Adjustment: The valve adjusts hydraulic oil flow according to operation demand, controlling the movement speed of executive elements such as boom telescopic speed or hook hoisting speed .
- Pressure Adjustment: Equipped with relief valves and other devices, it automatically releases excess pressure when system pressure exceeds the set value to protect the hydraulic system from damage .
- Load Sensing & Energy Saving: Distributes hydraulic flow according to actual load demand, avoiding unnecessary energy waste and reducing hydraulic system temperature rise .
- Safety Protection: Provides overload protection and prevents accidental operation to ensure safe crane operation .
Installation Location
This valve is installed in the crane's hydraulic system, typically positioned on the chassis for the lower control section .
