What is the SHANTUI Hydraulic Control Multiple Directional Valve？

  • The Hydraulic Control Multiple Directional Valve in the SHANTUI SL60W Wheel Loader is a core component that regulates hydraulic fluid flow, pressure, and direction to power critical functions like lifting, tilting, and steering. Engineered for durability and precision, this valve integrates robust materials and sealed components to handle high pressures (up to 25 MPa) in harsh working environments. Below is a detailed breakdown of its key parts:​
  • 1. Structural Foundation & Sealing​
  • Valve body: A high-strength cast iron housing with precision-machined internal passages, serving as the central framework for all components. Its design minimizes pressure loss while withstanding extreme operational stresses.​
  • Head cover & Valve Cover: Forged steel covers that seal the valve body, secured by Bolt to prevent debris intrusion. 0-rubber gasket ring (nitrile rubber) creates a leakproof seal between the covers and valve body, ensuring hydraulic fluid integrity.​
  • Cover board: A protective steel plate that shields exposed valve rods and internal parts from impacts and contamination.​
  • 2. Flow Control & Valve Rods​
  • Rotating valve rod & Movable arm valve rod: Precision-ground steel rods that slide or rotate within the valve body to open/close fluid passages. The Rotating valve rod manages directional flow, while the Movable arm valve rod controls lifting/tilting cylinder actuation, enabling smooth, proportional movement.​
  • Valve rod joint: A hardened steel connector that links valve rods to external control levers, translating operator input into precise valve movement.​
  • 3. Pressure Regulation & Safety​
  • Check valve: A one-way valve that allows fluid flow in one direction (e.g., to lift cylinders) while preventing backflow, ensuring load-holding stability during lifting operations.​
  • Overload valve & Safety Valve: Protective valves that limit system pressure to prevent component damage. The Overload valve safeguards against excessive force in lifting/tilting, while the Safety Valve relieves pressure spikes, enhancing system longevity.​
  • 4. Spring & Slippage Components​
  • Spring & Spring seat: High-tensile steel springs (housed in Spring seat) provide reset force to valve rods, ensuring they return to neutral positions when not actuated. This maintains consistent flow control and prevents unintended movement.​
  • Slippage valve & Slippage valve cover: A pressure-compensated valve that adjusts flow rate based on load, optimizing efficiency. The Slippage valve cover protects internal components, with an 0-rubber gasket ring sealing the interface to prevent leaks.​
  • 5. Fasteners & Plugs​
  • Plug screw: A threaded steel plug that seals unused ports in the valve body, with an 0-rubber gasket ring ensuring a tight seal during maintenance or system customization.​
  • System Functionality​
  • The valve operates by directing pressurized fluid from the hydraulic pump to actuators (cylinders) via the Rotating valve rod and Movable arm valve rod. When the operator adjusts controls, these rods shift to open specific passages, while Spring return them to neutral. Check valve prevents backflow, and Overload/Safety Valve regulate pressure, ensuring safe, efficient operation. Seals like the 0-rubber gasket ring minimize leaks, making this valve critical to the SL60W’s reliability in heavy-duty applications.
