Globe valves are one of the most commonly preferred types of valves for fluid control in many areas, from industrial facilities to domestic use. As the name suggests, these valves contain a perforated and rotating sphere inside. This sphere is rotated at 90-degree angles with the help of the valve handle to control the passage of fluid in the pipeline. When the valve handle is brought to a position parallel to the flow direction, the hole inside the sphere aligns with the flow, allowing the fluid to pass freely without any obstruction. By turning the handle 90 degrees, the sphere rotates to block the fluid and the system is completely closed.
Thanks to this simple yet effective working principle, globe valves have become indispensable in places where fluids need to be opened and closed quickly and reliably. They stand out in applications requiring frequent opening and closing due to their long lifespan, low pressure losses, and high sealing properties. Additionally, their compact designs take up very little space in the pipeline and their lightweight structures provide ease of installation.
One of the biggest advantages of globe valves is that they can be safely used with a wide variety of fluids. They offer high performance in controlling water, steam, natural gas, oil, chemical solutions, and fluids of different viscosities. Moreover, since they can be manufactured from different body materials such as stainless steel, cast iron, and brass, they can adapt to the different needs of both industrial and commercial facilities.
Today, globe valves, which have a wide range of applications from energy production facilities to the chemical industry, natural gas lines to water treatment plants, HVAC systems to the food industry, have become a symbol of reliability in industrial flow control.
The working principle of globe valves ensures their widespread preference in the industry due to their simplicity and high efficiency. Essentially, the perforated sphere inside the valve body is the main mechanism controlling the passage of the fluid. This sphere is rotated via the valve handle, allowing the fluid to be either freely flowing or cut off in the line.
When the valve handle is aligned with the flow direction, the hole in the center of the sphere also aligns with the fluid line. In this case, the fluid proceeds through the pipeline with minimal pressure loss, encountering no obstacles. This position is when the valve is fully open. When the valve handle is turned 90 degrees to a position perpendicular to the flow direction, the non-perforated surface of the sphere closes the line. Thus, the fluid passage is completely blocked, and the system is securely shut down.
This 90-degree rotational movement of globe valves offers both the advantage of quick opening and closing and operational ease. This feature is critically important, especially in emergencies or systems that frequently cycle on and off. For example, when a sudden interruption is needed in a water line, a globe valve can stop the flow with a single movement. Similarly, they are preferred in natural gas lines to meet high safety requirements.
Some globe valves are not only used in fully open and fully closed positions but can also be adjusted for a certain degree of flow control. However, this usage is generally limited; because prolonged partially open positions can cause wear on the sphere and seal surfaces. Nevertheless, globe valves offer a practical solution for short-term flow adjustments.
Another prominent aspect of the working principle is sealing. Globe valves are generally supported with PTFE (Teflon) seals. Thus, no matter how high the pressure or temperature of the fluid, full sealing is ensured when the valve is brought to the closed position. This feature is of vital importance for safety, especially in gas applications.
In conclusion, the working principle of globe valves is based on a simple yet effective mechanism: A rotating sphere opens or closes the path of the fluid. This simplicity makes them a low-maintenance and long-lasting flow control solution.
