Cast iron for horizontal installation, with thermostatic air vent

For pressures from vacuum to 30 psig (2 bar) . . .
Capacities to 8,900 lb/hr (4037 kg/hr)

Armstrong B and BI Series F&T traps combine high standards of
performance and long life with economy. They are ideal for heating
service where continuous drainage with high air-venting capacity is
required.

Due to the wide use of vacuum returns in systems of this type, the
thermostatic air vent element is charged to give it the capability of
compensated response to the pressure-temperature curve of steam at any
pressure from less than 20″ (500 mm) Hg vacuum to 30 psig (2 bar) gauge.
B and BI Series F&T traps will vent air slightly below steam
temperature throughout this entire range of operation.

All B Series traps, except the 1/2″ (15 mm) and 3/4″ (20 mm), have
inlet connections on both sides of the body to provide flexibility in
piping. The BI Series F&T traps in sizes 1/2″ (15 mm), 3/4″ (20 mm)
and 1″ (25 mm) feature the convenience of in-line connections with the
same internals as the B Series.
