ABSTRACT:
A fluid control device including a valve body, a control member, and a one-piece bonnet. The valve body defines a flow path for a fluid. The control member is disposed in the valve body and adapted for displacement between at least a first position and a second position. The one-piece bonnet is coupled to the valve body and defines a protrusion. The protrusion extends at least partially into the flow path and is arranged to direct at least some of the fluid flowing along the flow path when the control member is disposed between the first position and the second position.
