Engineer's Selection Guide: Globe Valves

Globe valves are linear-motion valves intended for throttling and regulating flow, at the cost of higher pressure drop than gate or ball valves. Selection focuses on trim type, flow-characteristic (linear/equal-percentage), body pattern (Z, Y, angle), and material compatibility for the service.

Frequently Asked Questions

Q: What is a globe valve used for?

A: Globe valves are used where flow regulation or throttling is required. They provide good shutoff and controllability but introduce a higher pressure drop than isolation-style valves.

Q: Which standards govern globe valves?

A: Common references include API 600 and BS 1873 for steel globe valves.

Guidance reflects general engineering practice for globe valves; confirm against the project specification and applicable standards before procurement.
