Jet Pipe Servo Valve (Replacement for Parker 410/Moog 771) Product Introduction
In the field of hydraulic control, the Parker 410 and Moog 771 series jet pipe servo valves have become industry benchmarks due to their stable performance. Our company has been deeply engaged in the R&D and manufacturing of jet pipe technology, and has now mastered fully mature core technologies. We launch jet pipe servo valve products that can accurately replace Parker 410 and Moog 771. Through customized processing technology and strict performance control, we achieve full matching in functionality, adaptability and reliability, providing efficient alternative solutions for hydraulic control systems in various industries.
Precise Parameter Configuration, Performance Comparable to Original
The product adopts a nozzle baffle-free jet pipe structure design, combined with an axial overlap dual-coil configuration. The axial overlap can be precisely adjusted within the range of 0—+1.5%, balancing control accuracy and structural stability. With a weight of less than 0.5kg, it has a lightweight advantage over similar products and is suitable for various compact installation scenarios.
Static Performance Indicators
The product exhibits excellent static performance, with a rated current of 40mA and a stable coil resistance of 80Ω, ensuring accurate conversion and transmission of electrical signals. The rated pressure reaches 21MPa, and the working pressure range covers 0.5-31.5MPa, which can adapt to multi-condition pressure requirements; the rated flow rate (Qn) is 19L/min, meeting medium and high flow control scenarios. In terms of control accuracy, the hysteresis is ≤4%, linearity ≤7.5%, symmetry ≤10%, zero bias ≤2%, and the resolution is as low as ≤0.25%, realizing micron-level precise control. The internal leakage is strictly controlled at ≤3%Qn+0.45 L/min, with extremely low leakage, effectively improving system energy efficiency; the pressure gain is ≥30%Pn/1%/In, ensuring the rapidity and stability of pressure response.
Dynamic Response Capability
Dynamic performance is the core competitiveness of servo valves. This product has an amplitude-frequency characteristic (-3dB) of ≥70Hz and a phase-frequency characteristic (-90°) of ≥90Hz, featuring fast signal response and dynamic adjustment capabilities. It can accurately capture instantaneous control commands, making it suitable for automated control scenarios with strict requirements on response speed. Its performance is fully comparable to the original Parker 410 and Moog 771 products.
Seamless Adaptation Design, Minimized Replacement Cost
The product adopts a universal installation design, fully compatible with the installation dimensions and interface standards of Parker 410 and Moog 771. It can be directly replaced in situ without structural modification of the original hydraulic system. To meet the special working condition requirements of different industries, our company provides comprehensive customized processing services. From coil parameters, flow and pressure adaptation to structural optimization, all can be adjusted according to the customer's actual application scenarios, realizing full-process adaptation support from product selection to installation and commissioning.
Mature Technical Support, Full-process Quality Control
Relying on years of experience in jet pipe servo valve R&D, our company has established a full-chain quality control system from core component processing to finished product inspection. Key components are manufactured using high-precision processing equipment, combined with a nozzle baffle-free jet pipe structure and axial overlap dual-coil design, which effectively improves the product's anti-interference ability and service life, ensuring stable operation under harsh working conditions such as high temperature, high pressure and high vibration. Each product undergoes strict performance testing before leaving the factory, with static and dynamic indicators verified one by one to ensure the consistency and reliability of delivered products.
Wide Application Scenarios, Empowering Industrial Upgrading
This product can be widely used in various fields such as industrial automation, aerospace, marine equipment, metallurgical machinery and power energy. It is suitable for various equipment including CNC machine tools, industrial robots, steering gear control systems and rolling mill hydraulic systems. It provides customers with cost-effective alternative solutions, helping enterprises reduce equipment maintenance costs, improve production efficiency and realize the upgrading and optimization of hydraulic control systems.
Our company always takes technological innovation as the core, continuously optimizes the performance of jet pipe servo valve products, and relies on mature customized processing capabilities and perfect after-sales service to provide global customers with high-quality alternatives to Parker 410 and Moog 771 jet pipes. We welcome customers from all walks of life to inquire and cooperate, and work together to create efficient and stable hydraulic control solutions.
