Globe valves are commonly used in industrial applications when it is necessary to control the flow of liquids or gases. The unique design of the globe valve, which includes a movable disc that can be opened or closed, provides superior control compared to other types of valves. Let’s take a closer look at what makes globe valves so useful and their properties and uses.
What is Globe Valves?
A globe valve consists of five main components – the body, the bonnet, the stem, the disk, and the seat ring. The body is made up of two halves joined together with bolts and nuts. Inside the body are two openings for the fluid to flow through; one at the top, where it enters and one at the bottom, where it exits. The bonnet is connected to the body by threaded joints or welding and contains an internal cavity for the stem assembly. The stem moves inside this cavity in order for it to open or close the valve. The disk is connected to the stem and seals against a seat in order to prevent any leakage from occurring when it is closed.
Globe Valve Properties
Globe valves have several important properties that make them ideal for many industrial applications. The most common type is constructed from cast iron or steel; however, they can also be made out of stainless steel or even bronze if necessary. These valves also have good pressure-retaining capabilities as well as excellent resistance to wear due to the unique design that isolates them from direct contact with fluids or gas. Additionally, these valves are easy to maintain because they can be easily disassembled without having to cut into any pipes or remove any fittings from other equipment. Lastly, globe valves offer superior control over other types of valves because they can be partially opened or shut off completely in order to regulate flow rate more precisely than other types of valves allow for.
- Globe valves are named for their spherical shape, which allows for a tight seal.
- Globe valves are used to regulate the flow of liquids and gases.
- The most common type of globe valve is the gate valve, which has a movable disk that opens and closes to control the flow of liquid or gas.
- Globe valves are also classified by their function, such as regulating, throttling, or shut-off valves.
- Globe valves are made from a variety of materials, including brass, bronze, stainless steel, and cast iron.
Globe Valve Uses
Globe valves are primarily used when precise control over liquid or gas flow rate is required, such as in chemical plants where large volumes need to be controlled accurately over long periods of time without any significant fluctuations in pressure levels across various points within the system. They are also commonly found in water treatment facilities, oil refineries, gas pipelines, power plants and many other industries that require regulated flows with minimal fluctuations due to their precision control capabilities compared with other types of valves like ball valves or gate valves, which lack this level of accuracy in controlling flow rates.
- Globe valves are used to regulate the flow of fluids in a variety of applications, including power plants, chemical plants, and oil refineries.
- Globe valves are designed to be installed in a piping system in such a way that the fluid being controlled can flow through the valve in either direction.
- The most common type of globe valve is the stop valve, which is used to shut off the flow of fluid in a piping system.
- Another common type of globe valve is the throttle valve, which is used to regulate the flow of fluid in a piping system.
- Globe valves are also available in a variety of other designs, such as check valves and safety valves.
Conclusion:
Globe Valves offer superior accuracy and reliability when controlling liquid or gas flows due to their unique design featuring a movable disk that seals against a seat allowing precise regulation of flow rate without causing significant pressure drops across various points within a system while being able to withstand wear better than most other types of valves available on today’s market due their high-quality construction materials such as cast iron, steel and stainless steel. When looking for an effective way to regulate liquid/ gas flows, whether it be in an industrial setting such as a chemical plant, water treatment facility, refinery, power plant etc., then you should consider investing in a globe valve which will provide you with all these features needed for efficient operation.
