Threaded globe valves come in various designs to suit different industrial applications. The primary types include:
These are the most common, known for their simplicity and costeffectiveness. They feature a spherical body with a movable disk to regulate flow.
Designed for highpressure systems, these valves offer a smaller port size to increase flow velocity and pressure drop efficiency.
With a larger port size, they minimize pressure drop and are ideal for highflow applications. Their threaded connection ensures easy installation in tight spaces.
Ensuring the integrity of threaded globe valves is paramount. Below are the key testing methods:
erforms using compressed air or water to detect leaks around the valve seat and stem. This method is crucial for maintaining globe valve testing methods compliance.
Subjecting the valve to operational pressure to verify its strength and sealing. Regular pressure testing ensures longevity and safety.
Evaluates the valve’s ability to regulate flow accurately. This is vital for systems requiring precise fluid control.
A detailed globe valve parts diagram helps in identifying each component and its function. The key parts include:
The main housing that contains the internal components and connects topipe.
Used to manually operate the valve, turning it clockwise to close and counterclockwise to open.
Transmits motion from the handle to the disk, controlling the flow.
Creates a seal with the disk to prevent leaks when the valve is closed.
erforms the isolation or regulation of flow by moving up and down within the valve.
Threaded globe valves are widely used in:
For regulating fluids in manufacturing and processing plants.
Essential for controlling water flow in purification systems.
Used in heating and cooling systems for precise temperature control.
