For use in any system where 2‑bolt technology may be used, the stand-alone 2-bolt connector block check valve offers the following beneficial features:

• Accommodates all Armstrong 2‑bolt block traps (inverted bucket, F&T, etc.). This check valve can also be used with any other manufacturer’s 2‑bolt steam trap.
• As a self‑contained item, the 2‑bolt check valve is easy to retrofit into any existing application. It is also easily replaceable without the need to purchase a new 2‑bolt trap.
• As a 2‑bolt product, this check valve offers ease of installation compared to a standard threaded check valve.

Armstrong 2‑bolt connector blocks and traps have provided reliable and fast installation and replacement for years. With the 2‑bolt connector block check valve, customers now have even more options for reducing installation and maintenance in their systems.
