What is the Dongfeng Hydraulic Oil Distributor

  • Dongfeng Hydraulic Oil Distributor: Precision Flow Control for Demanding Hydraulic Systems
    Engineered for reliability in agricultural, construction, and industrial machinery, the Dongfeng Hydraulic Oil Distributor delivers precise, leak-free directional control of hydraulic fluid. Its robust design ensures consistent performance under high pressure and varying loads, optimizing the operation of attached implements and hydraulic circuits.
  • Robust Core Structure & Sealing
  • High-Strength Distributor Body: Forms the central manifold, machined for precision fluid passages and component mounting.
  • Secure End Cover Assembly: Sealed with a critical Paper Gasket and fastened using Hex. Head Bolt M6x20 with Plain Washer 6-140HV, ensuring leak-proof closure of internal chambers.
  • Multi-Point Sealing System: Utilizes specialized O-Ring Seals (10.6×1.8, 10.6×2.65, 15×2.65) at critical junctions, complemented by Copper Washer 14 under the Square Head Oil Plug R1/4, providing superior pressure containment and preventing external leaks or contamination ingress.
  • Precision Control Mechanism
  • Handle Assembly (Handle Assy): Features an ergonomic Handle connected via a Pin 6×30 secured with a Split Pin 1.6×10, enabling intuitive operator control.
  • Fork & Valve Linkage: The Fork transmits handle movement directly to the Sliding Valve within the Fork Box. Valve position is positively held by the Positioning Bolt, Positioning Spring, and Steel Ball 9.5, creating a reliable detent mechanism for distinct flow paths.
  • Sliding Valve Core: The precision-ground Sliding Valve directs oil flow. Its movement is secured by a Slotted Spring Pin 6×22 and sealed internally with specific O-rings to prevent cross-port leakage.
  • Optimized Pressure Management & Safety
  • Integrated Safety Valve: Protects the system from overpressure damage. Consists of a Steel Ball dia.9, Ball Seat, Safety Valve Spring, Adjusting Shims for precise pressure calibration, and a sealed Plug.
  • Adjustment & Calibration: Adjusting Shims allow fine-tuning of the safety valve’s cracking pressure, ensuring system protection tailored to specific operational requirements.
  • Secure Assembly & Vibration Resistance
  • Heavy-Duty Fastening: Critical structural integrity is maintained using Hex. Head Bolt M8x75 with Spring Lock Washer 8, and Hex. Head Bolt M6×60, ensuring the distributor body and components withstand high vibration and pressure pulsations.
  • Auxiliary Components: Hex. Socket Cap Screws provide secure mounting points. A protective Pad and Sleeve elements offer additional impact resistance and alignment.
  • Engineered for Reliability & Long Service Life
    The Dongfeng Hydraulic Oil Distributor represents a complete, integrated flow control solution. The synergy of its precision-machined body (Distributor Body, Fork Box), meticulously selected seals (Paper Gasket, O-Rings, Copper Washer), robust fasteners (M6/M8 Bolts, Spring Lock Washers, Split Pin), and calibrated safety components (Adjusting Shims, Safety Valve Spring, Steel Balls) guarantees leak-free operation, precise control, and essential system protection. Designed to meet rigorous OEM specifications, it minimizes downtime and maximizes hydraulic system efficiency in the toughest operating environments.
