A globe valve is a type of linear motion valve used to regulate or stop the flow of fluid through a pipeline. It consists of a movable disk or plug and a stationary ring seat in a spherical body.

While martensitic steels exhibit exceptional hardness and strength, their corrosion resistance may be lower compared to other stainless steel types. They are better suited for applications where wear resistance and mechanical properties are crucial, rather than environments with high corrosion potential.

Globe valves operate by raising or lowering the valve disk or plug to control the flow of fluid. When the valve is fully open, the fluid flows in a straight line, and when it's closed, the disk or plug completely obstructs the flow.

Globe valves are commonly used in various industries, including power plants, petrochemical plants, and water treatment facilities. They are suitable for applications where precise flow control and shutoff are required.

Globe valves provide good throttling capability and precise flow control. They are also versatile and can handle a wide range of pressures and temperatures. Additionally, they offer a tight shutoff when fully closed.
