The SD line consists of heavy-duty, cast iron construction valves for use in pneumatic conveying and bulk material handling applications. The inner surfaces are precision-machined with tight tolerances to prevent tapering in the bore for a tight, effective air seal (for up to 15 psi, other pressures are available).

Introduction to Pneumatic Conveying of Solids - AIChE

Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.
