B0080S-3 Steam Trap for Steam Mains and Unit Heaters

This BELL & GOSSETT B0080S-3 steam trap is designed for steam mains and unit heaters in commercial heating systems. It features a cast iron body rated for 450F and a maximum allowable pressure of 250 psi. The in-line configuration includes an integral strainer and stainless steel lever assembly. It installs horizontally with a 5 1/16 in distance between ports.

Replaces worn traps to restore condensate removal

A failed trap wastes steam and reduces heating output; this unit handles a maximum capacity of 690 lb/hr at 80 psi differential. The non-asbestos fiber gasket and Grade 8 bolts ensure a reliable seal during service. Upgrading is justified when existing traps leak live steam or fail to discharge condensate at required rates.

Suits maintenance teams servicing horizontal steam

Facilities operating steam mains or unit heaters within a 0 to 80 psi range will match the trap’s design parameters. Systems requiring vertical installation or pressures above 80 psi differential need a different configuration. Buyers needing other body materials or capacities should select an alternative model.

Questions about this item

What pipe centre-to-centre distance does the B0080S-3 need for in-line mounting?

The trap requires 5 1/16 in between the inlet and outlet ports for horizontal in-line installation.

Which way up must the B0080S-3 be fitted and what is the common mistake?

Install it horizontally with the strainer pocket facing down; the error is mounting it vertically or upside-down, which blocks condensate flow.

When should the internal strainer on the B0080S-3 be cleaned or replaced?

Inspect and clean the non-asbestos gasket and stainless-steel strainer whenever capacity drops below the rated 690 lb/hr at 80 psi.
