Armstrong International B1670-4 Pressure Change Assembly

The Armstrong International B1670-4 Pressure Change Assembly is a precision-engineered steam trap repair kit specifically designed for inverted bucket traps including the Armstrong 212, 812, TVS-812, and 882 Series. Featuring a 5/32" orifice, this high-performance component allows your steam system to operate effectively at a maximum pressure of 125 PSI. By replacing the internal mechanism with this OEM PCA kit, HVAC technicians can restore optimal condensate drainage and prevent costly steam loss without replacing the entire trap body. The assembly consists of a durable valve seat, lever, and guide pin, ensuring a leak-proof shutoff and consistent pressure regulation in demanding industrial environments. Utilizing the Armstrong B1670-4 as a direct replacement part enhances the longevity of your heating infrastructure while maintaining peak energy efficiency and system reliability.

Key Benefits:

• Precision Flow Control: The 5/32" orifice ensures accurate fluid regulation for stable steam trap operation.
• Direct Compatibility: Engineered for seamless fitment in 212, 812, TVS-812, and 882 Series traps.
• Extended Service Life: High-quality construction resists corrosion and wear in high-pressure 125 PSI applications.
• Improved Efficiency: Minimizes steam bypass and maximizes condensate removal to reduce fuel costs.

Common Questions:

How do I know if I need a pressure change assembly (PCA)?
If your steam trap is failing to open under higher pressures or if you are changing the operating pressure of your system, a B1670-4 PCA is required to match the orifice size to the new maximum pressure requirements.

Is the Armstrong B1670-4 an OEM part?
Yes, this is an authentic Armstrong International component, ensuring strict adherence to original technical specifications and HVACR industry standards.

Does this kit include the bucket?
The B1670-4 is a mechanism-less bucket PCA kit, typically including the valve, seat, lever, and pins. If your bucket is damaged, it should be purchased separately to ensure full inverted bucket trap functionality.
