The Types and Uses of Globe Valves

Valves are critical components that regulate the flow of liquids, gasses, and slurries in fluid control systems across multiple sectors. Among the numerous types of valves available, the globe valve stands out for its reliability in controlling fluid flow. In this blog, we will explore a few of the types and uses of globe valves to illustrate their significance in fluid control systems, ensuring that you have the knowledge to make informed purchasing decisions.

Essentially, globe valves manage fluid flow within systems using a movable disk and a stationary ring seat that sit within their spherical body. When the valve is open, fluid flows through the space between the disk and the seat until adjusted to have both components pressed against each other. This design allows for fine control over flow, making it highly effective for precise regulation. They also provide an effective seal when closed to minimize leaks, which is particularly important when fluid loss could result in safety hazards or significant economic impact. Furthermore, globe valves are known for their durability and long service life, even in demanding, high-pressure, or corrosive environments.

As an example of use, globe valves are employed in water and wastewater treatment facilities, serving to manage the flow of fluids and chemicals through each process of treatment. Their robust design and reliable performance make them suitable for handling the varying flow rates and pressures encountered in these environments. They are also prevalent in power generation plants, where they regulate steam and cooling water to ensure that turbines and other critical equipment operate within intended parameters. Moreover, in the process industries, globe valves are frequently used to control the flow of steam, water, and chemicals. As they can withstand high temperatures and pressures, they are ideal for use in refineries, chemical plants, and other industrial facilities for maintaining safe and efficient operations.

To meet specific needs within these vast applications, globe valves are available in different types. When it comes to popular options, the most prominent variations are standard and angle globe valves. The standard globe valve is typically found in systems like pipelines, process industries, and other environments where a tight shut-off capability is desired. When the valve is opened, the disk is lifted away from the seat to allow fluid to pass through a narrow passage that is intentionally curved and extended for a longer route. This results in a controlled and steady change in direction that minimizes the risk of fluid hammer—a potentially damaging pressure surge that can occur in high-pressure systems when flow changes suddenly.

Another popular type is the angle globe valve, which is distinguished by its unique 90-degree turn between its inlet and outlet ports. This device serves dual purposes as a valve and as a directional change fitting, eliminating the need for additional piping to achieve changes in flow direction. Additionally, the 90-degree design contributes to a smoother flow by reducing sharp turns and sudden changes in flow direction, which can otherwise lead to turbulence and pressure drop. As such, angle globe valves are particularly useful in systems where space constraints are a concern or where installation complexity needs to be minimized.
