The Armstrong International B and BI Series Float and Thermostatic Steam Trap provides reliable condensate drainage and high air-venting capacity for heating applications. Designed for long-lasting performance and efficiency, these traps ensure continuous operation while maintaining economy. Their thermostatic air vent is engineered for a responsive reaction to the steam pressure to temperature curve, allowing for effective air removal at all operating pressures, from vacuum conditions up to 30psig.
The B Series features dual inlet connections (except for 1/2in and 3/4in sizes), providing flexible installation options. The BI Series, available in sizes 1/2in, 3/4in, and 1in, is designed with in-line connections for seamless integration into piping systems. Constructed with a durable cast iron body (ASTM A48 Class 30) and stainless steel internals, these traps offer excellent resistance to wear and corrosion.
