Globe Valves
Globe valves, named for their spherical body shape, are designed for precise flow regulation and shut-off, featuring an internal baffle with a seat and a movable disc to control fluid flow.
Available in cast and forged steel, globe valves are critical in industries such as oil and gas, chemical processing, and power generation, offering reliable performance in high-pressure systems.
Globe valves feature a spherical body divided by an internal baffle, forming a seat where a movable disc (or plug) regulates or stops flow. Their design excels in throttling applications, providing precise flow control, unlike gate valves which are suited for on-off service. Cast steel globe valves are used in larger, high-pressure systems, while forged steel variants are ideal for smaller, high-integrity applications. Their robust construction and versatile connection options ensure durability in demanding industrial environments.
Globe valves are manufactured to meet rigorous industry standards, ensuring performance and compatibility in various systems.
