ANSI Flange Globe Valve

Description

An ANSI flange globe valve is a type of valve that is designed to regulate the flow of fluids within a pipeline or system. It is commonly used in industrial applications, particularly in systems where precise flow control and shut-off capabilities are essential. The term “ANSI flange” refers to the specific standard for flange dimensions established by the American National Standards Institute (ANSI).

Here are some key characteristics and features of an ANSI flange globe valve:

1. Design and Construction: The valve comprises a globe-shaped body with a movable disc (or plug) inside. The disc is connected to a stem, which is operated by a handwheel, actuator, or other mechanisms. When the handwheel or actuator is turned, the disc either moves away from or towards the valve seat, controlling the flow of the fluid.
2. Flow Control: The design of the globe valve allows for precise flow control. By adjusting the position of the disc relative to the valve seat, the flow rate can be regulated. This makes globe valves suitable for applications where fine-tuning of flow rates is required.
3. Pressure Drop: Globe valves tend to have a higher pressure drop compared to other types of valves like ball valves due to the flow path created by the valve’s design. This factor should be considered when selecting a valve for a specific application.
4. ANSI Flange Connection: The valve is designed with flanges that adhere to ANSI standards for dimensions and compatibility. These flanges enable the valve to be securely attached to pipes or other equipment using matching flange connections.
5. Materials and Applications: ANSI flange globe valves are available in various materials to suit different media and environmental conditions. They are used in a wide range of industries, including oil and gas, petrochemicals, power generation, water treatment, and more.
6. Sizing and Configurations: These valves come in various sizes and configurations to accommodate different flow rates and pressure ratings. Different types of globe valves, such as straight-pattern, angle-pattern, and Y-pattern, are available to suit specific installation requirements.
7. Regulation and Shut-Off: Globe valves excel in both flow regulation and shut-off capabilities. They can be used to accurately control flow rates or completely stop the flow when needed.

In summary, an ANSI flange globe valve is a valve designed for precise flow control and shut-off applications, utilizing a globe-shaped body and a movable disc operated by a stem. The ANSI flange connections ensure standardized compatibility with piping systems, making these valves suitable for a wide range of industrial applications.
