There are two halves to this valve that has separation of the internal baffle.

The stems in these valves are not threaded but have an actuator assembly which helps them to open and close and function as needed. The spherical shapes of the valves gave the name globe valves . The new pipes don’t necessarily have that shape but have retained them as they have the same internal mechanism associated with the mentioned valves.
