MOOG 771K/772K/773K Explosion-Proof Servo Valves Drop-in Replacement for Gas Turbines
- Same mounting & interface, no modification
- Matches original performance
- Chinese Ex certification
- Competitive price & shorter lead time
For cross-reference, it serves as drop-in alternative for MOOG G771K/G772K/G773K series.
This servo valve is a drop-in alternative to MOOG G771K, G772K and G773K intrinsically safe explosion-proof servo valves, engineered primarily for gas turbine control systems. It adopts two-stage nozzle-flapper mechanical feedback structure, fully matching the original mounting interface, hydraulic parameters and electrical control signal requirements, allowing direct retrofit without mechanical modification.
Key Features
- Two-stage mechanical feedback servo design, low hysteresis, high resolution and excellent zero stability
- Same ISO mounting pattern and port layout as MOOG G77XK series, plug-and-play replacement
- Wide flow range covering 4~57 L/min, max working pressure up to 210 bar
- Intrinsically safe explosion-proof design for hazardous area operation
- Fluorocarbon sealing, strong vibration and shock resistance, long service life
- Chinese explosion-proof certification expected by end of 2026; ATEX certification not planned temporarily
Typical Applications
- Gas turbine fuel control & governor actuation system
- Power generation hazardous environment control
- Petrochemical hydraulic control equipment
- Explosion-proof test benches and industrial high-precision hydraulic position/force control
