Understanding Rotary Valve Design
Housing & End-plates. Rotary valves are made up of 4 main parts; cylinder (or housing), end-plates, rotor, and drive package. Magnum Systems' rotary valves are made from cast gray iron, stainless steel and or Hard Chrome. The reason the housings are made out of a cast mold is the strength it adds to the design that is not possible if just fabricated.
