Product Description
Product: 12-230-0851-T – Woodward LQ Series Servo Valve Coil Assembly
Woodward 12-230-0851-T Proportional Solenoid Coil for LQ Fuel Servo Valve & 9907-135 Driver Module
12-230-0851-T is an original Woodward proportional solenoid coil assembly with revision suffix T, dedicated matching LQ series fuel servo valves (LQ3, LQ25, LQ25T) and paired with 9907-135 GS3/LQ valve driver module. It is the core electromagnetic driving component of turbine fuel control loop, converting proportional current output from driver into linear magnetic force to adjust fuel valve spool stroke, precisely control gas/oil fuel flow of gas turbines, diesel generator sets and industrial steam turbines. The suffix T represents factory insulation reinforcement treatment, high temperature resistant winding coating for long-term operation in hot cabinet environments.

Main Functional Features
- High linear proportional electromagnetic output, realize precise continuous adjustment of fuel valve opening to stabilize unit speed under variable load conditions
- T version reinforced insulation encapsulation, effectively avoid winding short circuit burnout caused by long-term high temperature operation in turbine cabinet
- Low hysteresis winding design, small response lag, fast follow-up of 4–20mA speed control command from SCC-C governor
- Integrated built-in surge absorption diode, suppress reverse electromotive force impact when drive power is cut off to protect 9907-135 driver circuit
- Sealed integral structure, resist fuel oil mist, high temperature and vibration interference in engine room and fuel control cabinet environment
- Standard plug-in aviation terminal, convenient field wiring disassembly without cutting cable harness during maintenance replacement
- Perfect matching with Woodward SCC-C speed controller, 2301D governor and 9907-135 driver to form complete closed-loop fuel regulation system
- Independent winding fault tolerance design, single coil partial short circuit will trigger driver fault alarm to avoid unit runaway risk
