Globe valves are a type of industrial valve used to control fluid flow in various systems. Due to their distinctive design and precise flow regulation capabilities, they are utilized across many industries.
Structure and characteristics of globe valves:
- Body Structure: Globe valves typically feature a spherical or pear-shaped body through which the fluid flow path changes direction indirectly.
- Sealing: These valves utilize a movable disc (or plug) to control flow; this component is pressed against a valve seat to shut off or restrict the fluid flow.
- Connections: Connections for this type of valve are typically flanged or welded.
How it works:
Globe valves shut off or regulate fluid flow through the movement of a disc against its seat. As the disc approaches the seat, the flow is restricted or cut off, and as it moves away, the flow is released. Due to their complex flow path, these valves are highly capable of precise flow regulation.
Types of globe valves:
- Standard globe valve: For flow control in industrial systems.
- Special-design globe valve: For specialized applications, such as high-temperature and high-pressure conditions or specific fluids.
Advantages:
High precision in flow regulation: Due to their specific design, globe valves are suitable for precise flow control and pressure regulation.
Good performance at high pressures: These valves operate effectively under high-pressure conditions.
Ease of maintenance: They feature a simpler design compared to some other types of valves.
Disadvantages:
Significant pressure drop: Due to the complex flow path within the valve, a substantial pressure drop may occur in the system.
Requirement for extensive movement to regulate flow: In some models, significant movement of the disc is required to precisely regulate the flow.
Applications:
Oil and gas industries: For precise control of fluid flow in petroleum processes.
Petrochemical and chemical sectors: In systems requiring precise pressure and temperature control.
Water and wastewater systems: For regulating water flow within distribution networks.
Due to their precise operation and high adjustability, globe valves are widely used across various industries and are considered an excellent choice for flow control.
This type of valve is available in sizes ranging from 25 to 300 mm and in various classes.
