Gas Turbine Fuel Control Valve Model 8402 Overview The 8402G Fuel Valve System is a balanced rotary valve with an electric stepper-motor actuator. This high performance gas turbine fuel control valve with fast operation speed and large turn down ratio is designed for reliable an efficient control of any gas turbine. Typical applications l Custom designed specifically for gas fuel control (metering) for industrial or aeroderivative gas turbines l Combined with AMOT’s 4420 fuel shutoff valve, the 8402 can provide the complete gas turbine fuel control solution Key benefits l Precise turbine control - allows a single valve to be used where two valves were previously required. Model 8402 Gas Turbine Fuel Control Valve l Full stroke operating speed of 250ms l Digital optical encoder provides absolute repeatability of +/-0.05% of stroke l Carbon steel or stainless steel construction - durable for long life l electric - eliminates need for a hydraulic All actuation system

Gas Turbine Fuel Control Valve - Model 8402 Operation To meet the demands of virtually any industrial or aero-derivative gas turbine, the 8402 is equipped with an electric stepper-motor actuator, which can fully stroke the valve in only 250ms. The valve itself has a 500:1 turn down ratio which, in many applications, allows a single 8402 valve to provide precise fuel delivery to the turbine from light off to maximum power. This combination of features enables the value to enhance the performance of any gas turbine or turbomachinery train. the turbine operating in its maximum efficiency range...
