Description
The Armstrong International B1669-4 is a precision-engineered Pressure Change Assembly designed specifically for use with Armstrong’s 211, 310, 800, 811, TVS-811, 880, 881, 981, and EM Series Inverted Bucket Steam Traps. This genuine OEM replacement assembly allows technicians to reconfigure an existing inverted bucket trap to operate at a different pressure range without replacing the entire trap body, delivering significant cost savings and reduced system downtime.
Featuring a 1/8″ orifice, the B1669-4 is sized for lower-flow, lower-pressure steam applications and is an essential component for maintaining optimal condensate drainage and steam system efficiency. Armstrong International is a globally recognized leader in steam system solutions, and this assembly reflects their commitment to quality, durability, and precise steam management.

Application
Inverted bucket steam traps are widely used in industrial and commercial steam distribution systems to efficiently discharge condensate while preventing steam loss. When system operating pressures change, the B1669-4 Pressure Change Assembly provides a fast, cost-effective solution to re-rate the trap for the new pressure conditions. This assembly is ideal for maintenance engineers and steam system technicians looking to optimize trap performance without incurring the expense of full trap replacement.
