What is the SHANTUI Co-axis Amp Orbit-roll Valve？

  • The Co-axis Amp Orbit-roll Valve in the SHANTUI SL60W Wheel Loader is a critical hydraulic control component engineered to regulate fluid flow with exceptional precision, enabling smooth, responsive steering in heavy-duty operations. This compact, high-performance valve integrates robust materials and intricate design to handle high pressure (up to 16 MPa) while ensuring reliable operation in harsh environments. Below is a detailed breakdown of its key components:​
  • 1. Structural Core​
  • Valve Body: A high-strength cast iron housing with precision-machined internal passages, forming the foundation for all components. Its robust design resists deformation under pressure, maintaining consistent fluid flow paths.​
  • Front Cover & Rear Cover: Forged steel covers that seal the valve body, secured by Hollow-head Bolt (grade 10.9) and Light Spring Washer to prevent loosening from vibration. These covers protect internal parts from debris and moisture.​
  • 2. Sealing & Locking Mechanisms​
  • “O” Lock Ring & “X” Lock Ring: Elastic rubber seals (nitrile or fluorocarbon) that prevent hydraulic fluid leaks between static and moving parts. “O” Lock Ring seals linear interfaces, while “X” Lock Ring handles higher pressure zones with enhanced stability.​
  • Combined Lock Ring: A multi-purpose steel ring that secures the valve spool and stator, preventing axial movement during operation.​
  • 3. Flow Control & Actuation​
  • Valve Spool: A precision-ground steel spool that slides within the valve body, regulating fluid flow by opening/closing passages. Its surface is chrome-plated for wear resistance and smooth movement.​
  • Tranter Stator: A fixed component with internal ports that directs fluid flow, working in tandem with the valve spool to modulate pressure and flow rate for precise steering control.​
  • Universal Driving Shaft: A splined steel shaft that transmits rotational input (from the steering wheel) to the valve spool, converting mechanical motion into hydraulic control.​
  • 4. Bearing & Support​
  • Thrusted Needle Bearing: A compact bearing that reduces friction between the valve spool and stator, enabling smooth, low-resistance movement even under high loads.​
  • Small Baffle Ring & Big Baffle Ring: Metal rings that guide fluid flow, preventing turbulence and ensuring efficient pressure transfer within the valve.​
  • 5. Adjustment & Stability​
  • Limited Post: A threaded steel post that limits the valve spool’s travel, preventing over-actuation and ensuring safe, controlled steering range.​
  • Spring Plate: A thin, flexible steel plate that provides subtle tension to the valve spool, enhancing response time and reducing backlash.​
  • 6. Fasteners & Assembly​
  • Socket cap screw: Low-profile screws that secure internal components like the baffle rings, with hex sockets for easy torque application.​
  • Forelock: A cotter pin that locks adjusting nuts, maintaining critical settings and preventing loosening.​
  • Cross Continuous Block: A machined block that connects the valve to external hydraulic lines, with ports aligned for seamless integration.​
  • System Functionality​
  • The Co-axis Amp Orbit-roll Valve acts as the “brain” of the SL60W’s steering system, translating operator input into precise hydraulic signals. When the steering wheel turns, the Universal Driving Shaft shifts the Valve Spool, which directs fluid to the steering cylinders via the Tranter Stator. Seals like “O” Lock Ring and bearings such as Thrusted Needle Bearing ensure efficiency, while Limited Post and Spring Plate guarantee safe, responsive control.​
  • This valve is engineered for durability, with components tested to withstand 10,000+ hours of operation, making it essential for the SL60W’s reliability in construction, mining, and material handling applications.​
