Globe valves are one of the most common and reliable control valves used to regulate liquid and gas flow. It provides precise flow control thanks to the disk and seat mechanism in its internal structure. These valves, which have a wide range of applications from industrial plants to domestic applications, are especially preferred in high pressure systems. The design of globe valves offers better sealing and precision compared to other valve types, as the fluid follows a linear path and creates a certain pressure drop in the valve body. Thanks to these features, they are used safely in many areas from water treatment plants to the petrochemical industry. <\/p>\n
Globe valves can be operated by manual, electric or pneumatic actuators and are available in a variety of materials. Materials such as brass, cast iron, stainless steel and bronze offer different levels of durability depending on the application. In terms of maintenance, they have a longer service life than other types of valves and can be easily repaired when necessary. In addition, in processes that require precise flow control, globe valves increase energy efficiency and reduce operating costs. In conclusion, globe valves play a critical role in modern flow control systems and stand out with their reliability and performance. <\/p>\n
What is Globe Valve?<\/h2>\n
Globe valve is a type of linear motion valve that allows the control of fluids (liquid or gas). Thanks to the disc and seat mechanism in its internal structure, it regulates the flow precisely, can open and close completely or provide partial flow control. It is generally preferred in systems where high pressure drop is allowed and offers excellent sealing. Globe valves have a wide range of applications from industrial plants to water treatment systems, from petrochemical plants to heating-cooling systems. <\/p>\n
Globe valves can be operated by manual, electric or pneumatic actuators and are usually manufactured from durable materials such as brass, stainless steel, cast iron or bronze. Since they provide better flow control compared to other valve types, they are especially preferred in processes where precise adjustments are required. However, due to its structure, it may cause higher pressure loss than other valve types. Thanks to their long life and reliability, globe valves are used as an indispensable component in many areas where flow control is critical. <\/p>\n
Structure of Globe Valves<\/h2>\n
Globe valves consist of several basic components. The body is the outer casing of the valve and is usually made of durable materials such as cast iron, stainless steel, bronze or brass. These materials ensure the valve’s long life and resistance to different types of fluids. <\/p>\n
One of the main components, the disk (plug), is the fundamental part that regulates the flow. The disk moves up and down, narrowing or completely closing the flow path. The shaft and spring mechanism that moves the disk allows it to open and close with the force applied by the user or an actuator. In addition, the sealing gasket and cluster (cover) components prevent fluid leakage and ensure efficient operation of the system. <\/p>\n
Working Principle of Globe Valves<\/h2>\n
Globe valves basically have a disk mechanism that moves on the stem. When the valve opens, the disk moves upwards, allowing the fluid to flow freely. When it closes, the disk snaps into the sealing gaskets underneath, completely shutting off the flow. This mechanism allows precise control of the flow. <\/p>\n
This type of valve is usually operated with the help of manual or automatic actuators. Manual globe valves are controlled by a handwheel, while automatic ones can be controlled by electric, pneumatic or hydraulic actuators. Especially in large diameter and high pressure systems, globe valves integrated with automation systems provide more efficient and reliable flow control. <\/p>\n
Advantages and Disadvantages of Globe Valves<\/h2>\n
Globe valves allow precise regulation of the fluid. They are highly effective in applications where the flow amount needs to be precisely adjusted. Thanks to their durable construction, they can operate smoothly for many years. In addition, their sealing performance is very high when properly designed. They are widely used in industrial plants, power plants, chemical processes, oil and gas plants, water treatment systems.<\/p>\n
However, globe valves also have some disadvantages. First of all, since the flow path in its internal structure is tortuous, it can cause a greater pressure loss compared to other valve types. This can reduce energy efficiency, especially in systems where high flow rates are required. It can also require more force than other types of valves during opening and closing operations and therefore the use of automatic actuators is recommended for large diameter valves. Production costs can also be higher than other valve types. <\/p>\n
Areas of Use<\/h2>\n
Globe valves have a wide range of applications and are successfully used in different sectors. They are preferred in water treatment and distribution systems where precise control of the fluid is required. They are also frequently used in high pressure fluid lines in the oil and gas industry. In the chemical process industry, globe valves are used to safely direct corrosive or hazardous chemicals. <\/p>\n
In power plants and steam systems, globe valves are widely preferred to control high temperature steam and liquid flows. In HVAC (Heating, Ventilation and Air Conditioning) systems, they provide indoor temperature control by regulating the flow of hot or cold water. They are also used in the ship and marine industry to regulate fluid flow in ship engines and auxiliary systems. <\/p>\n
As a result, globe valves are a type of valve that offers great advantages in applications requiring precise flow control. They are characterized by high precision, long service life, strong sealing properties and a wide range of applications. However, some disadvantages such as pressure loss and high cost should be considered. With proper use and maintenance, globe valves can provide long-term efficiency by improving system performance. For this reason, selecting the right valve for the intended use and not interrupting periodic maintenance processes are of great importance in terms of system safety and efficiency.
