We at SIO both manufacture and customize top-quality globe valves. These valves are a linear mechanism that is mainly used to start, regulate, and stop fluid flow. The globe disk can close the entire flow or can be completely removed. It will move in a perpendicular manner to the seat during the opening and shutting of globe valves.
This motion will create the annular gap between the seat ring and the disk that will slowly shut as the valve closes. This feature allows globe valves to have excellent throttling capacity that is needed to regulate the flow. There is a lesser chance of leakage because of the right contact between the seat ring and the disk. The angle they are positioned enables a tighter seal between them.
At SIO, you can rely that we will make the best globe valves for your fluid flow needs.
A globe valve is a type of linear motion valve used to start, stop, and control media flow. While most valves are named after the shape of their discs, a globe valve earned its name for its spherical body.
A typical globe valve may be used for isolation and throttling. This type of valve creates a slightly higher pressure drop than straight-through valves, such as gate valves, ball valves, and plug valves. This means that a globe valve is recommended in applications wherein the pressure drop is not an important factor.
As an experienced globe valve manufacturer, globe valve supplied by SIO is well-suited for applications that include high-pressure steam. It can also be used in cooling water systems, feed water, fuel oil systems, chemical feed, boiler drains and vents, turbine drains and seals, and more.
SIO globe valves are designed for application in high temperature conditions, i.e., more than 1150°C (2100°F). They can also tolerate extremely low cryogenic temperatures below -196°C.
SIO globe valves can withstand pressures ranging from Class #150 to #2500.
Globe valves manufactured by SIO have face-to-face dimensions that comply with ASME/ANSI B16.10.
SIO globe valves have flange end complied with ASME/ANSI B16.5.
Globe valves are mostly used in industries to deal with corrosive fluids. They are made with corrosion-resistant materials such as stainless steel, cast iron, etc., to provide durability to the valve.
Globe valves come in several types and some can withstand extremely high and low temperature and pressures.
A valve’s pressure class is generally determined by the pressure class of the piping system. You must first determine the design temperature and pressure of the piping system in order to select the proper pressure class for your globe valve.
SIO Globe valves are normally installed in pipelines whose sizes are already known. Assuming this is your situation, the globe valve’s size will be similar to the pipeline’s size.
We train our employees at SIO to maintain the highest standard of quality and security while manufacturing globe valves, resulting in improved products for our customers. In addition to using finite element analysis to evaluate fatigue, stress, and fluid flow, our Experts in Extreme Engineering guarantee that the materials we select will withstand even the most demanding environments.
Thousands of different types of valves are produced on a daily basis in our manufacturing facility each passing through specific quality tests. This is why SIO is the best globe valve manufacturer in China.
While globe valves are mainly used to control flow, they come in a variety of types that differ in materials, actuation, design, etc. To help you, discussed below are the different types of globe valves that will give you a clear idea on what type of globe valve will give you optimal results:
Stainless steel globe valves are used for corrosive materials, oil, gas, slurries, and other heavy fluids due to their durability. Typically, it is found in oil and gas companies, water and wastewater treatment centers, and chemical and petrochemical factories.
Bronze globe valves have outstanding durability and malleability. This type of valve is used both in commercial and industrial settings. HVAC systems, compressed air systems, cold and hot water systems, gas networks, and other utility services use these valves.
Brass globe valves are made from zinc and copper alloys, giving them a high level of versatility. It has a high melting point, making it ideal for applications requiring high pressure or temperature.
Cast iron valves have excellent temperature tolerance, with some regulating media flow with temperatures exceeding 1150°C (2100°F). Cast-iron globe valves are so strong that even after repeated vibrations, they typically remain untouched.
In addition to their durability, forged steel globe valves can operate at temperatures ranging from -196C to 700C, making them suitable for high-temperature and high-pressure applications.
Angle globe valves direct the flow of the process by 90 degrees without relying on an elbow or extra weld. Discs can therefore be opened adjacent to the flow of the process. Moreover, this design can handle slugging effects under fluctuating flow conditions.
Y-pattern or wye globe valves have angled stems and seats inclined at 45 degrees to the pipeline axis. These provide the minimum flow resistance possible. Often, this design is employed in severe applications and high-pressure where pressure drop is a key concern.
The most commonly used globe valve is the tee pattern or z-type. A simple design consists of a z barrier inside the body that houses the valve seat. These valves are commonly used in applications requiring throttling.
Specifically designed to withstand extremely cold temperatures, cryogenic globe valves are employed in many applications. Additionally, it is used in environments with high pressure and corrosive media.
High pressure globe valve has a pressure range of Class #150 to #2500. In addition to steam, oil, and water, high-pressure globe valves are perfect for power generation. These valves are used in power generation, oil and gas industries, petrochemical plants, refining, etc.
High-temperature globe valves are specifically designed to withstand extreme service temperatures, low temperatures, corrosion, abrasion, as well as high viscosity and vacuum. Its applications include fine chemicals, polymers and plastics, and cryogenic applications.
Manual globe valves are operated by turning a handwheel or crank.
A globe valve can be actuated with an electric actuator because it is cost-efficient, produces less noise, and ensures smooth operation. In order to operate an electric globe valve, electricity is converted into mechanical energy by an electric actuator.
Pneumatic globe valves can be controlled semi-automatically or automatically by pneumatic actuators. The pneumatic globe valve globe valve is operated with compressed air. Its fast-acting properties make it ideal for throttling services..
Hydraulic globe valves work with hydraulic actuators. They convert fluid pressure into mechanical energy through hydraulic pumps. Often, hydraulic actuators have fail-safe features that enable them to open or close globe valves in an emergency.
The two-way globe valve is used in a flow system with fluctuating flow, pressure, and temperature. Since it promotes system efficiency, this valve is used in industries such as power generation, oil and gas, water distribution, and chemical and petrochemical.
Two inlet ports of a three-way globe valve are combined to flow through one outlet port and divert the media flow. In industries that handle oils, chemicals, or water, a three-way globe valve is often used.
A flange is one of the most common end connections in industrial valves. Using a flanged end makes it easy to install and remove the globe valve from a pipeline. In globe valves sized 15 mm and larger, flanged ends are used.
If the ends of the pipelines are flat or plain, a socket weld globe valve is selected. Socket weld ends are used exclusively with steel globe valves sized 50 mm and smaller. This valve is mainly used for high-pressure and high-temperature applications that do not need regular disassembly.
A threaded globe valve is connected to pipelines by screws. It can also be used in steel and iron valves, depending on the system and application.
Buttweld globe valves have end connections that are beveled to match the thickness of the wall of the pipeline. The butt weld end connections are normally used for globe valves larger than 50 mm in diameter.
Single-seated globe valves have a simple design and few interior components. These attributes make them easy to maintain and access. They have one disc and one seat. These globe valves provide excellent shutoff and less vibration.
In a double-seated globe valve, there are two seating surfaces and two plugs that are installed inside the body. The valve is operated by using opposite pressures from the plugs to reduce the actuator force required.
Ball type globe valves are typically used for low-temperature and low-pressure applications. In addition to its ability to start and stop media streams, it also provides excellent throttling capabilities.
Globe valves with needle discs can provide better throttling services than other disc types. For different flow requirements, there are several tapered and long needle discs available.
An insert ring creates a positive shutoff in a globe valve that uses a composition disc.
Pressure Seal Bonnet Globe Valve is widely used in high-temperature and high-pressure applications. This mechanism seals the inner diameter of the body to the pressure seal gasket.
Among the types of bonnet connections, the screwed bonnet globe valve is the simplest. Despite its simple design, a screwed bonnet provides a strong, pressure-tight seal. This is a popular choice when the cost is the main concern.
A welded bonnet globe valve consists of a body and a bonnet that is welded directly together.
The bolted bonnet is the most common type of bonnet connection for globe valves. For better seating, a gasket is attached between the flange faces of the body and the bonnet.
