Armstrong part C3484-5: valve seat 15b5 15a5 f t for the Armstrong B5 float & thermostatic steam trap (B & BI Series).

Armstrong's B and BI Series float and thermostatic steam traps are made for heating service that needs continuous drainage and high air-venting capacity. The thermostatic air vent is charged to track the steam pressure-temperature curve from 20 inches of vacuum to 30 psig, venting air slightly below steam temperature across that range.
