The BD Series has external elbows attached to the bottom to save significant space compared to side-ported cylindrical designs. Stainless steel and aluminum valve bodies are welded to commercial pipe elbows, while PVC valves are glued to commercial elbows. If desired, flanges can be welded to the elbows as an option. Aluminum elbows are square in shape while stainless steel and PVC are rounded.
BD valves are used for gases, liquids, and mixed phase applications. For liquid applications, an application engineer will discuss the downstream piping design to make sure that water hammer (resonance) does not cause an issue.
