    摘要： Apparatus, including a diaphragm valve, is provided featuring a valve body (12) configured with at least one spherically-shaped valve body sealing surface (12a, 12b); and a diaphragm (14) configured with at least one diaphragm sealing surface (14a, 14b), and also configured to respond to an applied force and provide sealing contact between the at least one diaphragm sealing surface and the at least one spherically-shaped valve body sealing surface. The valve body is configured with a spherical weir (12a) having a spherical weir sealing surface (12b) configured with polish marks substantially perpendicular to a weir leak path. The valve body also has a circular rim having a spherically-shaped peripheral sealing surface configured with polish marks, many of which are substantially perpendicular to a shell leak path.
