Abstract
A diaphragm sealed flow cavity comprises a first body comprising a support surface, a diaphragm comprising an outer portion that is joined by a weld to the first body, a clamped portion, and an inner portion that is movable along an axis, with the clamped portion of the diaphragm being compressed between the bearing surface and the support surface. The diaphragm sealed flow cavity may include a cylindrical body having a crimped portion for joining the cylindrical body to the first body. The diaphragm sealed flow cavity may also include a member that applies a live load to the clamped portion of the diaphragm. In the exemplary embodiments, the diaphragm sealed flow cavity may be realized as part of a diaphragm flow control valve having a valve body, diaphragm and a housing.
