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
