High flow rotary valves with low actuation torques and flow forces were evaluated. These valves maintained the ability to meter flow for a range of rotor positions. The one objective that was not completely met, however, was the leakage performance of the metal to metal sealed rotary valve. This aspect of the design was concentrated upon in the design revisions for the project. The result of these revisions was a rotary valve design that showed great promise in minimizing the leakage of the valve to satisfactory rates. Also, a special rubber seal design reduced leakage to zero during stationary valve position.(Download PDF) (Export to EndNotes)
