Mechanism: a plug closing against a seat inside a body shaped to force a direction change
"A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body." The plug is "connected to a stem which is operated by screw action using a handwheel," and "as the plug is moved, more of the openings in the cage are exposed and flow is increased and vice versa" — the throttling behaviour a gate valve's lift-clear gate does not give. Body shape is what changes between the catalogue's listed patterns: straight T-pattern bodies keep inlet and outlet in line; angle bodies have ports set so "the outlet pipe is directed towards the bottom," which "allows the fluid to drain off" and "prevents clogging and/or corrosion of the valve components over a period of time"; and a Y-pattern body is built "straight at the bottom... [to] allow the fluid to pass through without difficulty" and "minimize[s] fluid clogging/corrosion in the long term."
