Middleeast valve is the largest Globe Valve suppliers Saudi Arabia. A globe valve is a type of linear motion valve used to regulate flow in a pipeline. It derives its name from the globe-like shape of its body. The valve consists of a movable disk or plug and a stationary ring seat in a spherical body. By moving the disk up or down, the flow of fluid through the valve can be controlled.

Globe Valve Trim:

The trim of a globe valve refers to the internal components of the valve that come into contact with the fluid being controlled. These components include the valve disk, seat, stem, and sometimes additional features such as cages, plugs, or guides. The choice of trim materials depends on factors such as the type of fluid, temperature, pressure, and corrosives of the environment in which the valve operates. Common trim materials include stainless steel, carbon steel, bronze, and various alloys.

Purpose and Usage:

The primary purpose of a globe valve is to regulate fluid flow within a pipeline. It achieves this by controlling the volume of fluid passing through the valve. Globe valves are particularly useful in applications where precise throttling or control of flow is required. They offer excellent shut-off capabilities due to their design, making them suitable for applications where tight shut-off is necessary, such as in steam systems, water treatment plants, and HVAC systems.

Difference Between Gate and Globe Valve:

While gate and globe valves are both used to regulate flow within pipelines, they have distinct differences in design and function. Gate valves are designed for on/off service and provide minimal resistance to flow when fully open. They utilize a flat gate that is raised and lowered to control flow. In contrast, globe valves are designed for throttling or regulating flow and offer better control over flow rates. They use a plug or disk that moves perpendicular to the flow to regulate fluid passage.

Components of a Globe Valve:

Body: The main outer casing of the valve, which houses the internal components and provides structural integrity.

Bonnet: The bonnet serves as a cover for the valve body and houses the stem, packing, and other internal components.

Disk or Plug: This is the movable component of the valve that controls the flow of fluid by either opening or closing the flow passage.

Seat: The stationary ring seat against which the disk or plug seals to control flow. It ensures tight shut-off when the valve is closed.

Stem: The stem connects the actuator (handwheel, motor, or pneumatic/hydraulic actuator) to the disk or plug, allowing for remote or manual operation of the valve.

Packing: Packing material is used to seal the space between the stem and the bonnet, preventing leakage of fluid along the stem.

Actuator: In some cases, globe valves may be equipped with actuators such as handwheels, electric motors, pneumatic or hydraulic cylinders to automate the operation of the valve.
