Globe valves operate by having a convex disc shaped plug raise and lower via a rising stem into a circular seat around the inside of the globe shaped body at the “equator”. The flow enters the “lower hemisphere” from one side, then travels up through the seat and exits through the outlet on the opposite side of the “northern hemisphere”. Globe valves are suitable for both on/off and throttling applications. There are 2-way globe valves that are a preferred choice for precise flow control and 3-way globe valves that are commonly used for mixing media from two inlet ports and directing that mixture through an outlet port.
