15B5 - 1-1/4" NPT, 11/32" Orifice, 15 PSI, Float and Thermostatic Trap

Armstrong B and BI Series Float & Thermostatic steam 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 Float & Thermostatic steam traps will vent air slightly below steam temperature throughout this entire range of operation.
