2 Quality Valves & Level Gauges SFA SFS FLOATING BALL VALVES ASME lass /2 2.½ ( 15 65) Flange to ASME FEATURES Te floating ball valve SFA as arbon steel boy an alloy steel trim suitable for ig temperature. Tanks to a new patente innovative seat an to arbon reinforce PTFE sealings, te valve is suitable for ot meia uner pressure, as steam or supereate water. Besies, tis ball valve is esigne to avoi leakages an fugitive emissions in te environment as well as to maintain a safe tigtness also in case of fire, so being suitable for angerous or flaable meia too. Te innovative feature of tis valve is te ouble sealing system, tat is te capability to grant sealing bot by ownstream seating, as in usual floating ball valves, an also by upstream seating (see Fig. 1). SFS ball valve as ientical features, but it is manufacture wit boy an trim in austenitic stainless steel. Terefore it is te ieal solution for corrosive meia or corrosive atmospere. Tose valves are bi-irectional an coul be fitte wit electric or pneumatic actuator. Valves are suitable wit full or reuce bore Working conition Fig. 1 Fig. 1 Reference Stanars PED Directive (97/23/E) ASME B16.5 for flange imension ASME B16.10 lass 300 for en to en imension ISO ( fugitive emission ) API607 ( fire safe ) Fig. 2 Fig. 2 sows operating range of valves Note: for temperatures uner -46, please apply to our Tecnical or Sales Department. 01
