SonicFlo Gas Fuel Control Valve
SonicFlo™ Gas Fuel Control Valve controls the flow of gas fuel to the combustion system of an industrial or utility gas turbine. The integral actuator is a single-acting spring-loaded design for failsafe operation. The actuator includes an onboard hydraulic filter for last chance filtration of the fluid to ensure reliability of the servo valve and actuator. The servo valve is electrically redundant with triple coil design. Feedback for the actuator is provided by a dual coil, dual rod LVDT (linear variable differential transformer) directly coupled to the hydraulic piston.
