Brief: Get an inside view of features that deliver consistent results in daily use. This video provides a detailed walkthrough of the A11VO95/130/145-LRDS Integrated Hydraulic Pump Control Valve, showcasing its pilot hydraulic control system and demonstrating how it enables stepless displacement adjustment for forestry machinery and other heavy-duty equipment.
Related Product Features:
  • Integrates constant power (LR), pressure cut-off, load-sensing (LS) and differential pressure compensation for comprehensive control.
  • Features a rated pressure of 350 bar and peak pressure of 400 bar for high-pressure heavy-duty operations.
  • Enables stepless displacement adjustment from 0 to Vgmax via pilot hydraulic control for precise operation matching.
  • Offers fast response time of ≤120ms and low energy consumption for efficient system performance.
  • Uses integrated design to reduce pipeline connections, lowering leakage and vibration risks.
  • Compatible with ISO 46 anti-wear hydraulic oil and operates in temperatures from -20℃ to 80℃.
  • Provides 100% compatibility with original A11VO pumps for easy installation and replacement.
  • Features wear-resistant and corrosion-resistant valve body with long-life alloy spring for durability.
FAQs:
  • What types of machinery is this hydraulic pump control valve suitable for?
    This control valve is mainly suitable for construction machinery like excavators and cranes, mining machinery including roadheaders, agricultural machinery such as large tractors, and forestry machinery like loggers, particularly in open-loop, high-pressure heavy-duty systems.
  • What are the key control features integrated in this valve?
    The valve integrates constant power (LR), pressure cut-off, load-sensing (LS) and differential pressure compensation, providing comprehensive control for variable-condition hydrostatic transmission systems.
  • How does this control valve handle maintenance and troubleshooting?
    For issues like no displacement adjustment, check pilot pressure and clean valve core impurities. For abnormal pressure, recalibrate the constant power valve and replace aged springs. For excessive leakage, replace FKM seals and check valve body fit clearance.
  • What are the pressure specifications and response characteristics?
    The valve has a nominal pressure of 350 bar with a peak of 400 bar, and features a fast response time of ≤120ms for pressure cut-off, ensuring stable system performance under heavy-duty conditions.
