What is a globe valve and when should I use it?

A globe valve uses a spherical or plug-shaped disc that moves perpendicularly to the seat to start or stop flow. Globe valves are the best choice for throttling and flow regulation applications because the disc movement is perpendicular to the seat, allowing precise flow control. They are ideal for applications requiring frequent operation, fine flow adjustment, or where bubble-tight sealing is critical.

What is the difference between API 600 and API 602 globe valves?

API 600 covers steel globe valves (Bolted Bonnet) for general service. API 602 covers compact globe valves (wedge disc, needle, or cage) typically for smaller sizes and higher pressures. API 602 valves are usually limited to NPS 1/2 to 4 and Class 800 to 2500.

What materials are available for globe valves?

Carbon Steel WCB/A216, Stainless Steel SS304/SS316/SS316L, Chrome Moly WC6/WC9, and Nickel Aluminium Bronze C95800 (NAB) for seawater service. Trim materials include SS316, Stellite 6, and Monel for seat and stem.

Can globe valves be used for steam service?

Yes. Globe valves are excellent for steam service. The pressure seal or bolted bonnet design handles high-temperature steam effectively. For saturated steam, Carbon Steel WCB is standard. For superheated steam, Chrome Moly (WC6/WC9) is preferred.
