Product Introduction
Company Profile
Product Features & Operation Points
- Standard Moog G631-3800B Bandel Power specifications (PN21MPa, 100L/min), two-stage electro-hydraulic servo structure, customized for Bandel Power plant precision control, suitable for hydraulic flow and pressure adjustment, meeting high-precision control requirements of power generation equipment.
- Two-stage servo design (nozzle-flapper + sliding spool), realizing high control accuracy (linearity ±0. 5%), fast response (15ms), adapting to frequent adjustment working conditions of Bandel Power plant hydraulic control systems, ensuring timely and precise control feedback.
- High-strength alloy steel body and precision ceramic spool, excellent pressure-bearing capacity, corrosion resistance and wear resistance, temperature adaptability (-20℃~90℃), good mechanical stability, ensuring long-term stable operation in harsh Bandel Power plant working environments.
- Moog original precision machining and assembly technology, strict control of key dimension tolerance within ±0. 01mm, good matching degree with hydraulic control loops, complying with ISO 4401, GB/T 10867 and power station precision control standards, avoiding servo failure caused by poor fitting.
- Complies with GBT, ISO and API standards, modular structure for easy installation, calibration and maintenance, fully matching Bandel Power plant hydraulic control system specifications, compatible with Moog original accessories, reducible maintenance costs and customizable according to project needs.
