Armstrong B1671-7 PCA Kit (Pressure Change Assembly)

The Armstrong B1671-7 PCA Kit is a pressure change assembly designed for use with Armstrong inverted bucket steam traps, specifically models such as 213, 313, and 316. This kit enables users to modify the operating pressure of the steam trap by replacing key internal components, including the valve, retainer, guide pin, and associated hardware. It ensures maximum efficiency in steam systems by allowing quick adjustments to pressure changes without replacing the entire trap assembly. Ideal for industrial applications in steam distribution, process heating, and condensate management, the kit is constructed from durable stainless steel for corrosion resistance and longevity in high-temperature, high-pressure environments. Benefits include cost savings through easy upgrades, reduced downtime during maintenance, and improved system performance. Compared to similar products from competitors like Spirax Sarco, the Armstrong kit offers superior compatibility with existing Armstrong traps and precise engineering for reliable sealing and flow control. Drawbacks may include the need for technical expertise during installation and compatibility limited to specific Armstrong models. The kit comes packaged with all necessary parts, making it suitable for field repairs or upgrades in facilities like power plants, refineries, and manufacturing plants. Condition analysis from provided images indicates the kit is new and unused, still in original packaging with intact labels and no visible wear. No serial number is evident on the faceplate, but part details include PCA 213/313/316 V-414 H9B. No parent/child assets are attached. Estimated market price range is $50-$100 USD based on comparable new listings on industrial supply sites like Grainger and eBay; this is an estimate as exact sales data varies.
