Globe Valve - types, features and applications

Introduction to Globe Valves

Globe valves are a type of industrial valve used to control the flow of fluids in piping systems. Due to their specific design, these valves offer precise flow regulation and are widely used in various industries, including oil, gas, petrochemical, and industrial facilities.

Structure and Operation

Globe valves consist of three main parts: the body, the disc, and the stem. The disc moves vertically, and by changing the position of the disc, the fluid flow is controlled. These valves create a high-pressure drop due to their specific design and are suitable for applications requiring precise flow control.

Types of Globe Valves

Globe valves are mainly divided into two types:

• Straight Globe Valves::These valves have a straight flow path and are suitable for applications requiring precise flow control.

• Angle Globe Valves::These valves have an angled flow path and are suitable for applications requiring a change in flow direction.

Advantages and Disadvantages

Advantages:

1. Precise flow regulation
2. Reliable performance under various conditions
3. Easy maintenance and repair
4. Long lifespan and high resistance to corrosion

Disadvantages:

1. High-pressure drop
2. Requires more force to open and close
3. Higher cost compared to some other types of valves

Applications

Globe valves are used in various industries such as oil, gas, petrochemical, industrial facilities, and power plants. Due to their precise flow regulation capability, these valves are very useful in systems requiring accurate control. Common applications include:

• Flow control in oil and gas pipelines
• Cooling systems in power plants
• Steam and hot water systems in industrial facilities
• Water and wastewater treatment systems

Conclusion

Globe valves are known for their precise flow regulation capabilities and are widely used in various industries such as oil, gas, petrochemical, and industrial facilities. These valves consist of three main parts: the body, the disc, and the stem, and the fluid flow is controlled by the vertical movement of the disc.

Globe valves are mainly divided into two types: straight and angle, each suitable for specific applications. The advantages of these valves include precise flow regulation, reliable performance, easy maintenance, and long lifespan. However, they also have some disadvantages, such as high-pressure drop and the need for more force to open and close.
