🔍 Key Concepts

• Compare the flow path shape inside a globe valve versus a gate valve • Identify whether the closure element looks like a plug/disk or a flat/rectangular gate • Look at where the threads on the stem engage and decide if the stem or the disk is moving up and down

💭 Think About

• Does the internal passage show a straight-through opening or does the flow change direction around a seated plug? • Is the moving part that seals against the seat shaped more like a plug sitting on a seat, or like a flat plate sliding across the flow? • From the drawing, does the threaded portion of the stem appear to travel through a fixed nut in the bonnet, or does it appear to be threaded directly into the disk at the bottom?

✅ Before You Answer

• Confirm if the body shape matches the typical Z-shaped flow of a globe valve or the straight bore of a gate valve • Check whether the disk/gate connection to the stem is threaded or uses a loose/ball joint connection • Verify whether the stem itself rises when operated, or if only the disk would rise while the stem remains in one axial position
