Working Principle of Hydraulic Servo Valves
The hydraulic servo valve series adopts built-in spool position detection and feedback structure, building a fully enclosed flow adjustment system. This innovative structural design drastically enhances positioning precision and operational repeatability, achieving micron-level accurate hydraulic motion control. Adopting integrated digital intelligent control modules, the product supports on-site parameter calibration, performance testing and functional optimization through special supporting software, greatly simplifying equipment debugging and daily maintenance work. The upgraded low-delay and low-hysteresis spool structure enables the valve to maintain stable, sensitive and consistent output response even under long-term cyclic signal changes and continuous high-frequency operation.
Complying with universal CETOP 08 industry installation standards, this series of servo valves can be directly mounted on hydraulic manifold blocks without auxiliary connecting accessories, optimizing equipment assembly structure and cutting overall installation and maintenance costs. The thickened and reinforced valve body is designed for long-term heavy industrial operation, with a maximum continuous bearing pressure of 350 bar, perfectly adapting to high-load, long-cycle industrial working scenarios. Equipped with IP65 industrial standard waterproof and dustproof electrical terminals, the valve can effectively isolate external dust, rainwater and humid air, ensuring stable and reliable operation in both indoor factory workshops and outdoor field operation environments. Additionally, the optional energy-saving flow recovery structure can effectively reduce the overall power consumption of hydraulic equipment during the large-stroke movement of hydraulic cylinders, realizing energy saving and efficient operation of industrial hydraulic systems.
