The floating ball valve SFA has Carbon steel body and alloy steel trim suitable for high temperature. Thanks to a new patented innovative seat and to Carbon reinforced PTFE sealings, the valve is suitable for hot media under pressure, as steam or superheated water. Besides, this ball valve is designed to avoid leakages and fugitive emissions in the environment as well as to maintain a safe tightness also in case of fire, so being suitable for dangerous or flammable media too.

The innovative feature of this valve is the "double sealing system", that is the capability to grant sealing both by downstream seating, as in usual floating ball valves, and also by upstream seating.

SFS ball valve has identical features, but it is manufactured with body and trim in austenitic stainless steel. Therefore it is the ideal solution for corrosive media or corrosive atmosphere.

Those valves are bi-directional and could be fitted with electric or pneumatic actuator.

Valves are suitable with full or reduced bore
