Abstract: An improved abrasion resistant rotor assembly and valve and system related thereto is disclosed. The assembly includes a rotor body defining an annular opening which surrounds a drive shaft and a plurality of vanes radially extending from the rotor body. The rotor is made up of a unitary ceramic component, such as silicon carbide. The valve also includes a body for defining a bore that receives the rotor assembly, where the body bore is likewise comprised of a hardened ceramic material. This valve may thus be used to convey abrasive particulate in an efficient manner from a supply container to a pressured line for further processing or disposal.
