The BD Series has external elbows attached to the ports on the bottom plate to save significant space compared to the side-ported cylindrical designs of our smaller regulators. Metal elbows are welded to the valve bodies while polymer elbows are glued. Standard elbows are NPT and there are options for BSPP, flanges and Tri Clamp.
BD valves are used for gases, liquids, and mixed phase applications and are particularly popular for fuel cell testing, biogas production, pump bypass pressure control, and other industrial 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.
