FCT Desuperheater Control Valve

FCT Desuperheater Control Valve – Efficient Steam Temperature Regulation

FCT Valve’s desuperheater control valves play a critical role in steam systems by reducing superheated steam temperature to the desired level. Using high-precision spray water injection through nozzle assemblies, these valves ensure responsive and accurate desuperheating, preventing thermal stress and improving system efficiency.
