Brief: See the journey from feature description to real application in this concise overview. This video showcases the A11VO190 pump with its matching LRDS integrated control valve, demonstrating how its pilot hydraulic control achieves precise displacement adjustment for high-power metallurgical equipment. You'll learn how this system provides stable pressure and flow output in demanding high-pressure, heavy-load environments.
Related Product Features:
  • Integrates constant power, pressure cut-off, load-sensing and differential pressure compensation for comprehensive control.
  • Designed for open circuits with a rated pressure of 350 bar and peak pressure of 400 bar.
  • Uses pilot hydraulic control to achieve stepless displacement adjustment from 0 to Vgmax.
  • Provides stable pressure and flow output for high-pressure heavy-load systems.
  • Features load-sensing control for high energy efficiency and system optimization.
  • Includes pressure limiter function to ensure system safety during operation.
  • Offers good dynamic response and control stability with response time ≤120ms.
  • Modular design enables easy integration and service maintenance.
FAQs:
  • What types of equipment is this pump control valve suitable for?
    This valve is mainly suitable for construction machinery like large excavators and cranes, mining machinery including heavy roadheaders, metallurgical equipment such as forging machinery, and port machinery like container cranes. It's particularly ideal for high-power hydrostatic transmission systems.
  • What should I check if experiencing insufficient flow or pressure?
    Check the load-sensing line (X-port) for any blockage or leakage, verify the pressure limiter setting is correct, and inspect the pump displacement mechanism for proper operation.
  • How does this control valve handle system safety?
    The valve includes a pressure limiter function that protects the system by preventing excessive pressure buildup, ensuring safe operation even under demanding high-pressure conditions up to 400 bar peak pressure.
  • What working conditions and media are compatible with this valve?
    The valve operates with ISO 46 anti-wear hydraulic oil within a temperature range of -20℃ to 80℃, with short-term operation possible up to 100℃, making it suitable for various industrial environments.
