Ball Valves - SFA/SFS
FLOATING BALL VALVES
ASME Class 150 - 300
1/2” ÷ 2.½” (DN 15 ÷ 65) Flanged to ASME
FEATURES
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 (see Fig. 1).
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
Reference Standards
