Bonnet Designs for Forged Steel Globe Valves

  • Bolted Bonnet: The valve body and bonnet are connected with bolts and nuts, and sealed with a spiral wound gasket (SS316 + graphite). Metal ring connections can be used based on customer requirements.
  • Welded Bonnet: The valve body and bonnet are connected with threads and sealed with a full welded joint.
  • Pressure Seal Bonnet: The valve body and bonnet are connected with threads and sealed with an internal pressure self-sealing ring.

Performance Characteristics of Forged Steel Globe Valves

  • The valve body is forged as a whole, providing high strength, an attractive appearance, and reliable material properties.
  • The middle cavity features a self-sealing structure where sealing improves with higher pressure. The stainless steel self-sealing ring is easy to disassemble and provides a dependable seal.
  • The valve stem surface is treated to be wear-resistant and corrosion-resistant, resulting in minimal opening and closing friction and preventing leakage.

Working Principle of Forged Steel Globe Valves

The forged steel globe valve is widely used due to its durability and ease of maintenance. The valve features low friction between sealing surfaces during opening and closing, which contributes to its longevity. It requires minimal opening height, is straightforward to manufacture, and is suitable for both medium and low pressure as well as high pressure applications.
 
The closing mechanism relies on the pressure from the stem to press the disc’s sealing surface against the valve seat’s sealing surface, effectively preventing medium flow.
 
Forged steel globe valves allow medium flow in only one direction and must be installed accordingly. Compared to forged steel gate valves, globe valves have a longer structural length and higher fluid resistance. They may also experience reduced sealing reliability during prolonged operation.

Specs of Socket Weld Globe Valve

Valve Operation
These valves use a handwheel for manual operation, allowing precise control over the valve’s position. The handwheel mechanism is designed for easy handling and efficient operation. This feature is essential for applications requiring frequent adjustments.
Stem Design
The valve’s stem is designed with a rising stem mechanism, indicating the valve’s open or closed position. This design helps with visual confirmation of the valve status. For instance, operators can quickly see whether the valve is open or closed, enhancing operational efficiency.. See the difference? A rising stem provides clear visual feedback, reducing operational errors.
Size and Dimensions
NTVAL offers valves in various sizes, ranging from 1/2 inch to 4 inches in diameter. This range allows for flexibility in fitting different pipeline systems. The compact design makes installation straightforward, even in tight spaces.

Features of Socket Weld Globe Valve

Precise Flow Control

The valve features a movable disc that allows for precise regulation of fluid flow. This design provides accurate control, which is crucial for maintaining the desired performance in complex systems. The handwheel operation adds to the ease of flow adjustments.

Metal-to-Metal Seat

The Socket Weld Globe Valve incorporates a metal-to-metal seat, offering a reliable and tight seal. This seat is resistant to high temperatures and abrasive materials, making it suitable for demanding industrial applications. The durable seat design extends the valve's service life.

4 Considerations When Buying Socket Weld Globe Valve

01

End Connections

Examine the end connections of the valve. Socket weld ends are recommended for high-pressure systems. However, it’s essential to match the valve’s end connections with your existing pipeline to avoid compatibility issues during installation. For example, if your pipeline uses threaded connections, you’ll need to verify the valve has compatible threaded ends or appropriate adapters.

02

Class VI Leakage Rating

Check the leakage class of the Socket Weld Globe Valve. A Class VI leakage rating is recommended for applications where leakage must be minimized. This high standard indicates a very tight seal, providing reliable operation in critical applications where even small leaks can be problematic.

03

Actuation Options

Evaluate the actuation options available. While manual handwheel operation is common, pneumatic or electric actuators can provide automated control. But you know what else? Automated actuation is ideal for remote or hard-to-reach locations, enhancing operational efficiency.

04

Cv Value

The Cv value, or flow coefficient, is a key consideration. For industrial applications, a Cv value ranging from 10 to 40 is ideal for balancing flow rate and pressure drop. This measurement helps in selecting a valve that meets your system’s flow requirements. NTVAL offers Socket Weld Globe Valves with Cv values tailored to various industrial needs, providing optimal performance and efficiency.
