Abstract
A valve assembly has a valve body and a fluid passage through the valve body with an inlet end and an outlet end. A valve seat is defined within the fluid passage. A sleeve is axially slidable within the fluid passage and has an upstream end, a downstream end, and an axial flow passage in communication with the inlet end and the outlet end of the fluid passage. A valve stem is pivotally mounted at a stem pivot spaced radially from the fluid passage. The valve stem is actuable to slide the sleeve between an open position with the downstream end spaced from the valve seat and a closed position with the downstream end borne against the valve seat to selectively control fluid flow through the flow passage to the outlet end.
