🔍 Key Concepts

• Globe valve internal construction – location of the seat and disk relative to the flow • How pressure on the disk affects the stem, packing, and ease of opening/closing • Difference between flow direction for stop valves (on/off) and throttling service

💭 Think About

• Sketch a simple globe valve in section and draw arrows showing flow from below the seat and from above the seat. In which case does pressure help keep the valve tightly shut? • Think about what happens when you try to open the valve against system pressure. From which side of the seat would you want the flow so that you don’t have to fight full system pressure on the disk? • Consider how flow direction affects wear on the seat and the ability to replace packing or work on the stem while there is still pressure in the line.

✅ Before You Answer

• Visualize where the seat is and which side of the disk is exposed to upstream pressure for each possible flow direction. • Confirm which direction gives better shutoff and reduces the load on the stem and packing when the valve is closed. • Verify standard practice for globe valves in throttling and isolation service in marine piping texts or manufacturer diagrams before choosing.
