Bolt-jointed bonnet GB gate valve

The body flange and bonnet flange are joined by studs and nuts, with a gasket of suitable design/material inserted between the flange faces to facilitate sealing. This in turn creates a seal between the gasket and the inner(I.D.) of the valve body. A segmented trust ring maintains the load.
