What type of valve is the finest for your application? How does one choose between various valve arrangements when there are many to consider? We’ll examine two common choices: globe valves vs ball valves.

They differ primarily in the way they close. Ball valves have gates (balls) that close across the flow, while globe valves use a plug (stem). But we can apply operating handle in both. Globe valves are better at controlling flow, whereas ball valves are better for on/off control with little pressure loss.

Evolution of Control Valves:

For a considerable amount of time, globe valves were the only option for control valves. Raising or lowering the valve’s stem adjusts the valve’s flow rate.

Moreover, people typically use larger versions to control the water temperature, pressure in chillers, and hot and cold water coils. We are talking about diameter. Globe valves’ close-off ratings may drop below those of alternative valves when used with pipes of greater diameter.

Globe valve working principle

The handwheel must be turned more than 360 degrees to open or close a globe valve. A globe valve consists of a body, bonnet, handwheel, stem, and plug, at the very least. In Figure, the letter A represents the valve body, which contains ports for inflowing and exiting media.

The bonnet shields the threaded valve portions (shown by the letter B in Figure). The plug (Figure, labeled D) may be adjusted in height by rotating the handwheel (Figure, labeled C).

When the plug is taken out, the orifice can be used. When the stopper is placed in the valve seat, flow is halted. When the disk is raised, however, the flow rate increases. The flow rate is greatest when the disc is at its highest possible altitude. The fluid flow velocity may be altered by repositioning the disc within the stem.

Inside Ball Design: Flow Control and Durability in Ball Valves

The design of ball valves uses an inside ball. The ball has a hole in the middle. This hole allows flow. Flow occurs when the hole lines up with both ends of the valve.

The hole in the valve is perpendicular to the ends of the valve when the ball is twisted 90 degrees and the valve is closed.

Ball valves usually keep their seal even after years of operation in an operating system. In shutoff applications, people generally prefer these valves over globe valves. As a result of the large flow amount the ball allows, ball valves have proportional control.

Understanding Globe Valves vs Ball Valves

Globe Valves vs Ball Valves are two commonly used valves in various industries. Both valves control the flow of fluids, but they have different designs, functions, and applications.

Globe Valves: Design, Operation, and Applications

Globe valves are round and used to control fluid flow precisely in specific situations. They have a linear motion stem that moves up and down to control fluid flow through the valve.

Ball Valves: Spherical Design and Versatile Applications

In designing Ball valves, conversely, they have a spherical ball-shaped disc with a hole in the middle. A ball within the valve body spins to either open or close the opening.

These valves find wide usage in HVAC and water distribution systems, as well as irrigation and water distribution.

Advantages of Globe Valves vs Ball Valves

  • Globe valves simplify flow management in four ways. They regulate and control flow accurately in various applications. They achieve this by using their linear stem.
  • They maintain precision in either high- or low-pressure settings. Globe valves are ideal for uses that need fine flow control because of their exceptional throttling characteristics.
  • In contrast, ball valves have earned a stellar reputation for their dependability and longevity in the industry. Due to their simplicity, they require less repairs.
  • Ball valves are adaptable due to their high heat and pressure resistance. A low-pressure drop indicates that the operation wastes less power, which is intriguing when discussing energy efficiency.

Disadvantages of Globe Valves vs Ball Valves

  1. Regarding disadvantages, globe valves have a higher pressure drop than ball valves, affecting the system’s overall efficiency. When you design the surfaces, they also require more maintenance due to their complex design and multiple sealing surfaces.
  2. In preferences, Ball valves, although durable, may provide a different level of precision in flow control than globe valves. They are better suited for on/off applications than fine-tuning the flow.

Choosing the Right Valve: Factors to Consider

Here are the factors to consider when choosing the suitable valve:

  • Application Requirements:
  • Flow Control Needs:
  • Operating Conditions:
  • Fluid Type:
  • Industry Standards:
  • Material Compatibility:
  • Valve Size:
  • System Compatibility:
  • Pressure Drops:
  • Maintenance Requirements:
  • Cost vs. Performance:
  • Environmental Considerations:


Globe Valves vs Ball Valves have advantages and disadvantages. The application requires specific flow control, pressure, temperature, and fluid type. It is necessary to consider these factors when selecting the appropriate valve for a particular system or process.
