F&Ts contain a float-operated valve to continually discharge condensate and a thermostatic air vent which discharges air. Body materials available are Cast Iron, Ductile Iron, Cast Steel, & Stainless Steel for pressure up to 450 psig. F&Ts are the most commonly used trap for the majority of process applications. These traps are also suitable for drip applications on pressures 30 psig & below. F&Ts quickly respond to load and pressure changes Discharge large amounts of air present at start-up which allow steam to quickly enter the system.
