Bolted Bonnet Globe Valve

Which are some typical applications and industries where Globe Valves are usually used?

Because they are reliable and accurate in controlling fluid flows, Globe Valves have very wide applications across many sectors. In the oil and gas industry refining processes, petrochemical plants, and natural gas distribution systems frequently use them. These valves are also widely used in power production facilities to regulate steam and water movement within boilers and turbine sets. Moreover, they find use in water treatment sites where they determine water supply velocity as well as provide steady state pumping conditions.

Also, they play an important role when it comes to regulating heating/cooling fluids flows in HVAC (heating ventilation air-conditioning) systems. Further on Globe Valves are utilized for precise fluid adjustment in pharmaceutical manufacturing plants, food processing industries among other industrial processes. Globe Valves with their inherent flexibility contribute largely to efficiency and safety of diverse industries.

What parts constitute a globe valve and what functions do they perform in controlling flow?

A number of major components are necessary for regulating fluid passage inside pipes to make up a Globe Valve. Important components include body , bonnet , plug (disk), stem, and seat. A body serves as the outer shell enclosing other valve parts on the inside. The bonnet, which encloses the stem, provides a seal between it and the body. Control of flow is carried out by a movable plug or disk. As we raise or lower this plug with a stem, it interacts with the seat, which is a ring-shaped surface located inside the body, to allow or restrict the passage of fluid through it. When the plug opens up, fluid flows through it while when the plug makes contact with its seat flow ceases.
