A Large Bakeable Vacuum Valve

PDF Version Also Available for Download.

Description

The development and design of a large bakeable valve based on a unique seat arrangement and a novel motion seal are described. The seat sealing is accomplished through the use of high pressure fluid actuation of an annular pinch gasket. Experimental data on seat closure performance, and the specific design features to achieve successful closures, are presented. The bakeable motion seal utilizes a stainless steel bellows sleeving over an inner concentric actuating shaft. This shaft is bent at 90 deg to the axis of rotation and is free to rotate relative to the bellows. There is no apparent size limitation ... continued below

The design of a 10-inch gate valve utilizing these principles is described. (auth)
