10 Things to Consider When Buying Thread Type Globe Valve

Introduction

In the world of fluid control systems, the importance of choosing the right valve cannot be overstated. Globe valves are a common and versatile type of valve used in various industries, and selecting the right one can significantly impact the efficiency and safety of your operations. To make an informed decision, it's essential to consider several factors and work with reputable Globe Valve Manufacturers and Suppliers. In this blog, we will explore key selection tips and considerations to help you choose the right globe valve for your specific application.

Understanding Globe Valves

Before diving into the selection process, let's have a basic understanding of what globe valves are and how they work. Globe valves are linear motion valves that control the flow of fluids by moving a disc (or plug) along a seat, which regulates the flow rate. These valves are used to start, stop, and regulate the flow of liquids, gases, or steam in various applications, including industrial, commercial, and residential systems.

Selection Tips and Considerations

1. Application and Fluid Compatibility: One of the first considerations when selecting a globe valve is the application and the type of fluid it will be handling. Different applications require different materials and designs to ensure optimal performance and durability. Consider factors such as the fluid's temperature, pressure, corrosiveness, and viscosity to choose the right materials and valve design. Consult with experienced Globe Valve Manufacturers and Suppliers who can provide guidance on material compatibility. 2. Valve Size and Pressure Rating: The valve size and pressure rating must match your system's requirements. Oversized or undersized globe valves can lead to inefficiencies, increased energy consumption, or even system failures. Refer to industry standards and consult with experts to determine the appropriate valve size and pressure rating for your application. 3. Flow Control: Globe valves are versatile when it comes to flow control. They can be used for on-off service or for throttling and regulating flow. If precise flow control is required, consider selecting a valve with a design optimized for throttling applications. Keep in mind that improper flow control can lead to excessive wear and reduced valve lifespan. 4. Materials of Construction: Globe valves are available in various materials, including stainless steel, brass, bronze, cast iron, and more. The choice of material depends on factors like fluid compatibility, temperature, and corrosion resistance. For example, stainless steel is suitable for corrosive fluids, while bronze is often chosen for seawater applications. Consult with Globe Valve Manufacturers and Suppliers to determine the best material for your needs. 5. Bonnet Type: Globe valves have two common bonnet types: bolted bonnet and pressure seal bonnet. The choice between the two depends on the pressure and temperature requirements of your system. Pressure seal bonnets are suitable for high-pressure applications, while bolted bonnets are generally used for lower-pressure systems. 6. Sealing Mechanism: Globe valves can have different sealing mechanisms, including globe, plug, and needle. The choice of sealing mechanism affects the valve's ability to provide a tight shut-off and control the flow accurately. Consider the level of leakage tolerance acceptable for your application and choose the appropriate sealing mechanism accordingly. 7. Actuation: Globe valves can be operated manually, pneumatically, electrically, or hydraulically. The choice of actuation depends on factors like the valve's size, accessibility, and the need for remote control. For large or hard-to-reach valves, automated actuation systems may be necessary for convenience and efficiency. 8. Maintenance and Accessibility: Globe valves, like all mechanical equipment, require regular maintenance. Consider ease of access for maintenance when selecting a valve. Valves with readily accessible components and spare parts availability can reduce downtime and maintenance costs. 9.

What are the Key Components of a Globe Valve?

The components of a globe valve include the stem, bonnet, plug, and body!

Source : Wikipedia 

1) Body

The body is the main pressure-containing structure of the valve and is the most easily identified as it forms the mass of the valve. It contains all of the valve’s internal parts that will come in contact with the substance being controlled by the valve.

2) Bonnet

The bonnet provides a leak-proof closure for the valve body. The threaded section of the stem goes through a hole with matching threads in the bonnet. Globe valves may have a screw-in, union, or bolted bonnet.

3) Plug Or Disc

The valve’s closure mechanism involves plugs that connect to a stem, which is adjusted either by sliding or screwing it up or down to regulate flow.

3) Stem

The stem connects the actuator to the inside of the valve and transmits this actuation force. Stems are either smooth for actuator-controlled valves or threaded for manual valves.

How Does a Globe Valve Work?

Source: Growmechnical

A globe control valve works by using globe valve parts, such as a movable plug or disc that presses down onto a seat to control flow. When you turn the handwheel, the stem moves the disc up or down. Lifting the disc allows fluid to pass through; lowering it blocks or reduces the flow. Its shape like a globe forces the fluid to change direction, which helps slow it down and gives you better control. 

Globe valve uses a disc (like a plug) to stop, allow, or control the flow of fluid.

1) Closed Position:

When the valve is closed, the disc is pressed tightly against the seat (the opening), so no fluid can pass through.

2) Opening the Valve:

Turning the handwheel counterclockwise lifts the disc off the seat. As the disc rises, fluid starts flowing.

3) Flow Control:

The higher the disc is, the more fluid can pass. The lower it sits, the less fluid flows. This makes globe control valves great for controlling flow, not just stopping or starting it.

4) Closing the Valve:

Turning the handwheel clockwise lowers the disc back onto the seat, blocking the flow again.

Types of Globe Valves

Not all globe valves are built the same. Their shape changes how they work, how much they resist flow, and how easy they are to maintain.

5) LNG (Liquefied Natural Gas)

Globe valves are often cryogenic-rated in LNG terminals and storage tanks, managing flow at temperatures below -150°C. They regulate gas transfer during liquefaction and vaporization, preventing vapour lock or sudden pressure spikes.

6) Chemical Processing

In chemical plants, flow conditions often change rapidly requiring valves that respond quickly, safely, and precisely. Globe valves control dosing chemicals into reactors, manage cooling water loops, and help avoid cross-contamination between process lines.

7) Pharmaceuticals

Pharmaceutical environments demand valves that meet cleanroom and sanitary standards. Globe valves are used for batch fluid regulation, sterilization-in-place (SIP), and water-for-injection (WFI) systems. They provide smooth control without fluid stagnation.

8) Space Research & Aerospace

Globe valves handle gases like helium or hydrogen, cooling fluids, and oxidizers in aerospace testing labs and launch systems. They provide critical control in systems where even milliseconds of delay or tiny pressure changes can affect outcomes.

9) Mining & Metals

Used in cooling water systems, steam lines, and chemical addition in ore processing, globe valves must withstand abrasive flows and dust-heavy atmospheres. Their ability to throttle flow without full actuation makes them ideal for frequent, low-maintenance operation.

10) Industrial Gases & Cryogenic Systems

These systems require valves that can precisely meter flow under extremely low temperatures and avoid freezing or cavitation. Globe control valves with vacuum or steam jackets are often used in oxygen, nitrogen, and argon lines.

11) Food & Beverage

Globe valves are used in steam injection, cleaning-in-place (CIP) lines, pasteurization, and flavour dosing in F&B processing. They must handle high temperatures and be easy to clean. Stainless-steel sanitary globe valves meet these needs with minimal dead zones.

12) Sugar Plants & Distilleries

These facilities rely on steam for boiling, condensing, and fermenting. Globe valves provide the control needed to maintain stable pressure in boilers and condensers, directly impacting product yield and energy usage.

How to Choose the Right Globe Valve?

1) Know Your Flow Requirement

Globe valves are ideal if your system requires frequent throttling or precise flow control. However, considering the flow rate and direction, standard globe valves cause a pressure drop, which may not suit high-flow systems unless designed accordingly.

Understand the Operating Pressure and Temperature

2) Understand the Operating Pressure and Temperature

Globe valves come in forged or cast bodies with different pressure classes. Make sure the valve can withstand your system’s maximum pressure and temperature range, especially in steam, LNG, or cryogenic applications.

3) Consider the Fluid Type

Globe valves come in forged or cast bodies with different pressure classes. Make sure the valve can withstand your system’s maximum pressure and temperature range, especially in steam, LNG, or cryogenic applications.

Consider the Fluid Type

4) Choose the Right Valve Type

Is your media corrosive, abrasive, viscous, or clean? This impacts both material selection (SS, brass, alloy) and internal trim design (hard-faced seats, Teflon seals, etc.)

Different globe valve types suit different installation and flow needs:

Z-type: Best for tight shut-off and general use

Y-type: Lower pressure drop, ideal for high-frequency throttling

Angle type: Compact and good for directional flow change

Cryogenic jacketed: Required for ultra-low temperatures

Jacketed (steam/oil): Keeps fluid from solidifying (e.g., wax, bitumen)

5) Actuation Method Matters

Consider this question: Should the valve be operated manually, pneumatically, or electrically? Choose actuation based on accessibility, speed of response, and system automation.

Maintenance and Service Access

6) Maintenance and Service Access

If downtime is costly, go for designs that are easy to dismantle and maintain. Bolted bonnets and top-entry designs simplify seat and disc inspection or replacement.

7) Check Standards and Certifications

Ensure the valve complies with API, ASME, BS, or ISO standards relevant to your industry. Pharma, LNG, food, and nuclear sectors have stricter design and testing norms.
