The Armstrong B2 Cast Iron Float and Thermostatic Steam Trap is engineered for reliable performance in industrial steam and HVAC systems. Built with a ASTM A48 Class 30 Cast Iron body, this float and thermostatic steam trap delivers efficient operation and long service life.
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.
Key Features
- Continuous condensate drainage with no backup
- High air-venting capacity via thermostatic element
- Responds instantly to changing condensate loads
- Suitable for vacuum return systems
- ASTM A48 Class 30 Cast Iron body construction
Applications
Designed for commercial and industrial steam systems where reliable float and thermostatic condensate removal is essential.
