Polished Metal Globe Valve, Mounting Type : Horizontal

Listing ID #781322

A globe valve is a workhorse in the world of valves, used for both regulating flow rate and completely shutting off fluid flow in pipelines. Here's a quick breakdown:

· Design: It has a spherical body (hence the name "globe") with an internal disc or plug that controls the flow path. The disc is connected to a stem operated by a handwheel or actuator.

· Function: By turning the handwheel or activating the actuator, the disc is raised or lowered within the body, regulating the opening size and consequently the flow rate. In the fully closed position, the disc creates a tight seal to stop the flow entirely.

· Applications: Globe valves are widely used in various industries due to their versatility. Some common applications include:

o Flow control: Regulating flow rate in pipelines for processes requiring precise control, like boiler feedwater or chemical processing plants.

o Isolation: Completely shutting off flow to isolate specific sections of a pipeline for maintenance or repairs.

o General purpose: Used in various plumbing and HVAC systems for flow control and shutoff needs.

· Advantages:

o Versatility: Can handle both flow regulation and complete shutoff.

o Good pressure handling: Suitable for a wide range of pressure applications.

o Throttling capability: Allows for fine-tuning of flow rate.

· Disadvantages:

o Higher pressure drop: The internal flow path can cause a larger pressure drop compared to some other valve designs.

o Not ideal for high-viscosity fluids: The disc design may not be suitable for very viscous fluids.
