Understanding Globe Valves: Types and Functions

Globe valves are crucial components in industrial valve systems designed to regulate the flow of various liquids and gases. Different types of globe valves available in the market offer unique designs to suit specific applications.

Standard Globe Valve: This type of valve is the most common, designed with a plug that moves up and down in the valve body to regulate flow. The unique feature of this valve is that it can partially or fully close the valve, making it ideal for applications requiring precise flow control.

Angle Globe Valve: This is a type of valve that has the inlet and outlet passages at an angle of about 90 degrees. It is best suited for applications that require frequent shutoffs, as the valve can partially close without causing damage to the valve body.

Three-Way Globe Valve: This type of valve is designed to handle three-way flow, operating as both a mixing and a diverting valve. It is commonly used in heating and cooling systems.

The functions of globe valves are precise flow regulation, adjustable throttling, and accurate shutoff. These functions play a crucial role in different industrial applications, such as oil and gas, water treatment, power generation, etc.

"Globe valves offer unique designs to suit specific applications and can regulate flow, throttle, and shutoff liquids and gases efficiently, making them indispensable in many industrial applications."

Globe Valve Specifications and Sizes

Globe valves are essential components in various industrial applications due to their precise flow control mechanisms. To choose the right valve for your specific requirements, it is crucial to understand the available valve specifications and sizes.

The valve's diameter and pressure rating are critical factors in determining its performance. Globe valves are available in different diameters ranging from DN10 to DN400, and pressure ratings from PN1.6MPa to PN335MPa. The selection of the right diameter is determined by the flow rate, while the pressure rating is determined by the system's pressure.

For instance, in a low-pressure system, a DN25 globe valve with a PN16 pressure rating would suffice. On the other hand, in a high-pressure system, a DN100 globe valve with a PN100 pressure rating would be necessary to handle the system's pressure and flow requirements.

Standard Globe Valve Sizes and Specifications

The standard sizes and specifications vary based on the valve's type, material, and application. The table below outlines the standard sizes and specifications for various globe valve types:

Medium Temperature Range for Globe Valves

Globe valves have a wide operating temperature range, making them suitable for various industrial applications. The valves can operate in temperatures as low as -100℃ and as high as 425℃. This range is achievable due to the robust design and materials used for these valves, which enable them to withstand extreme temperatures.

The wide temperature range also makes globe valves suitable for applications in diverse industries, from chemical processing to power generation. For instance, globe valves are used in chemical plants to regulate the flow of high-temperature fluids, and in power plants to regulate and direct the flow of steam and other gases.

When selecting a globe valve for your application, it is essential to consider the required operating temperature range carefully. Choose a valve that can handle the specific temperature range of your application to ensure optimal performance and durability.

Globe Valve Connection Options

Choosing the right connection option is crucial to ensuring optimal performance of globe valves in various valve applications. There are four primary connection types available: flanged, threaded, welding, and lug.

Flanged Connection

Flanged connections involve bolting two flanges together with a gasket in between to form a tight seal. This connection type is suitable for applications that require frequent valve maintenance or where the valve needs to be removed for servicing. Flanged globe valves are available in a range of sizes, from DN15 to DN400.

Threaded Connection

Threaded connections are designed for smaller-sized and lower-pressure globe valves. They are convenient for applications that require frequent valve replacement or when the valve needs to be quickly removed for maintenance.

Welding Connection

Welding connections are suitable for applications that require high-pressure and high-temperature tolerance. Welded connections provide a permanent seal and are ideal for minimizing fluid leaks. Welded globe valves are typically used in petrochemical, chemical, and oil and gas industries.

Lug Connection

Lug connections involve bolts and nuts attaching the valve to the pipeline, which allows for easy valve replacement without the need to remove the surrounding pipe. This connection type is less expensive than flanged connections and is ideal for low-pressure applications.

By selecting the most appropriate connection option for a specific valve application, end-users can enjoy optimal valve functions and performance.

Compliance with Industry Standards: API 600 and API 6D

When it comes to purchasing globe valves, it's essential to ensure that the valves comply with relevant industry standards. Two of the most crucial standards are API 600 and API 6D, established by the American Petroleum Institute (API).

API 600 specifies the design and testing requirements for steel gate, globe, and check valves intended for use in the petroleum and natural gas industry. This means that valves that comply with API 600 have undergone rigorous testing to ensure their quality and reliability in harsh industrial environments.

API 6D, on the other hand, applies to pipeline valves used in the transportation of petroleum and natural gas. This standard outlines the design and testing requirements for valves used to isolate pipeline sections or initiate emergency shutdowns. Compliance with API 6D ensures that the valves can withstand high-pressure and high-temperature applications, ensuring safe and efficient operation.

When choosing globe valves, it's crucial to opt for products that meet these standards. This ensures that you're investing in high-quality valves that offer superior performance and reliability, making them a cost-effective choice in the long run.
