Abstract: A valve (100) comprises a valve seat (102) and a movable diaphragm (104). The valve seat (102) defines a fluid orifice (106) and is formed at least partially of polybenzimidazole. The diaphragm (104) is sized and configured to bear against the fluid orifice (106) to substantially block fluid flow through the orifice (106). The valve (100) is advantageously used in a hot zone (34) of a semiconductor processing system.
