Advantages
High Sensitivity And Fast Response
The servo valve incorporates a high-performance torque motor, rapidly converting weak electrical signals into high-power hydraulic output. The response time is only 6-9 milliseconds, and the undamped pilot stage has a natural frequency of up to 500Hz, allowing for instantaneous valve core position adjustment to meet the demands of systems with high dynamic performance requirements.
High Flow Utilization Efficiency
Over 90% of the pilot stage flow is effectively utilized, significantly reducing power consumption. This advantage is particularly pronounced in equipment using multiple servo valves simultaneously.
High Control Precision
Utilizing a hard alloy feedback rod and a precision-ground four-way spool valve structure, the flow gain is stable, with excellent linearity and repeatability. Control precision reaches the micron level, with a resolution of less than 0.5%.
Excellent Dynamic Response Performance
The two-stage hydraulic amplifier design, combined with a dual-nozzle baffle valve structure, provides fast step response and a frequency response of 90-180Hz (±10% signal, -3dB). The system loop gain is high, and both static and dynamic characteristics are excellent.
Strong Low-Pressure Control Capability
The minimum control pressure is only 25 bar, making it suitable for low-pressure systems such as steam turbine control, expanding its application range.
Strong Anti-Pollution Capability
Utilizing a special valve core and sleeve structure with a built-in 200μm gap filter, its lifespan is nearly unlimited. It can operate stably under harsh conditions, reducing jamming failures and ensuring high reliability and long lifespan. The robust and simple structure, using high-quality materials and advanced manufacturing processes, along with mechanical feedback design, ensures long-term stable operation and low maintenance costs.
Stable Pressure Gain Characteristics
The servo jet tube pilot valve has a relatively flat pressure gain curve, ensuring stable and reliable performance, maintaining good performance even under hydraulic interference.
Compact Structure And Modular Design
The overall structure is compact, occupying little space, facilitating equipment integration and installation. The modular design makes installation and maintenance more convenient.
Application Areas
Industrial Manufacturing
Applications include metal processing equipment (rolling mills, CNC machine tools), injection molding machines, blow molding machinery, and general industrial machinery. Precise control of hydraulic cylinder movement ensures processing accuracy, improving production efficiency and product quality.
Aerospace
Flight simulators, aircraft control systems, and aviation testing equipment. Compliant with SAE-ARP-490 aviation standards, it accurately simulates hydraulic changes under flight conditions, providing reliable control for pilot training and aircraft design testing.
Energy And Petrochemicals
Oil and gas exploration equipment, power plant equipment, and steam turbine control systems. Its low-pressure control characteristics make it suitable for low-pressure systems such as steam turbines, achieving stable and reliable hydraulic regulation in energy production.
Testing And Experimentation Equipment
Material testing machines, vibration testing benches, and seismic simulation testing machines. High dynamic response and precise control capabilities allow for accurate control of loading forces and vibration frequencies, ensuring the accuracy of test data.
Metallurgical Industry
Metal forming equipment and aluminum cold rolling mills.
Application Value
Maintains high-precision control under heavy-duty conditions, improving the quality of rolled products and production stability.
