3. Core Advantage Matrix

Advantage Area Concrete Manifestation Value to the Customer
Precision & Efficiency "On-demand" flow delivery via proportional control, eliminating throttling and overflow losses common in fixed-displacement systems. Significantly reduces energy consumption (fuel/electricity), lowers system heat generation, and extends component life.
Intelligent Control Integrated electronics support multiple control modes (pressure, flow, power, load sensing). CAN bus communication enabled. Enhances machine operability and automation, facilitating easy integration into intelligent control systems.
Superior Reliability High-pressure rating, optimized critical friction pairs, and robust construction for heavy-duty and shock-load applications. Ensures long-term, stable operation in harsh environments, minimizing downtime and maintenance costs.
Compact & Quiet High power density design. Optimized internal flow paths reduce fluid pulsation and noise emission. Saves installation space, improves operator comfort, and helps meet stringent environmental noise regulations.
