Abstract
Internal valve apparatus are described. An example internal valve includes a body having a valve seat disposed in a fluid flow passageway between an inlet and an outlet. A flow control member is operatively coupled to the body and movable between a first position to engage the valve seat to restrict fluid flow through the valve and a second position to move away from the valve seat to allow fluid flow through the valve. A removable actuator is coupled to the body and operatively coupled to the flow control member to cause the flow control member to move between the first and second positions. A portion of the removable actuator is cantilevered in the fluid flow passageway between the inlet and the outlet when the removable actuator is coupled to the body.
