Abstract
An inline process valve assembly having a valve body of a rigid material having a thru bore which is circular in cross-section forming a flow passage extending through the valve body along a longitudinal axis and having a lower arcuate surface. A cone-shaped recess is formed in the body and has a central vertical axis extending perpendicular to the longitudinal axis. The cone-shaped recess opens into the flow passage and has an hemispherical rounded nose which is generally coincident with the lower arcuate surface of the flow passage. A cone-shaped diaphragm of a flexible material disposed in said cone-shaped recess and is movable between open and closed positions with respect to the flow passage. The diaphragm has an outer margin. A clamp is provided for clamping the outer margin of the diaphragm to the valve body to form a liquid-tight and air-tight seal between the diaphragm and the body. An operator is secured to the diaphragm for moving the diaphragm between said open and closed positions.
