A globe valve controls flow with a plug moving onto a seat inside a globe-shaped body. It throttles well, so it is used where flow has to be adjusted rather than only opened or closed.

Valve, globe type. Drawn the same way: a solid dot where the triangles meet.
German (DIN): Durchgangsventil. See DIN P&ID symbols.
Where you see it on a P&ID
On bypasses around control valves, on throttling duties, on small lines and drains.
Tag codes
The globe valve is commonly tagged:
- HV
- as the body of FV, PV, LV, TV control valves
Tag formats follow the project numbering procedure. For instruments, the letters follow ISA 5.1, explained on the instrument symbols page.
