Globe Valves

What Is Globe Valves? Types and Parts
 

The globe valve, which controls the flow of liquid using a linear motion, is one of the types of valves that can be used to exert control over the flow of liquid. The globe valve disc has the capability of completely blocking off the flow route, or it can be withdrawn from the flow path entirely. When the valve is opened or closed, the disc rotates in a direction that is perpendicular to the seat.

This action gradually decreases the annular space that is present between the disc and the seat ring as the valve is closed. Because of this property, the globe valve is capable of effectively limiting the flow when that function is required.

Types of Globe Valves
 

Here is some different types of globe valves 

1. Z-type Globe Valve

This globe valve design is the most elementary of all those available. With this design, a large pressure drop is produced because the disc is attached to the stem and rotates at right angles to the valve axis. 

It is employed in situations where high pressure-drop is not an issue. Excellent fluid restriction is one of its many strengths. The fluid pressure drop at perpendicular angles is extreme.

2. Angle Type Globe Valve

It functions similarly to a Z-type valve but with minor adjustments. An acute angle, 90 degrees, is present in the fluid's flow path. Since it can smooth out erratic fluid flows, it is often utilised in pulsing applications.

3. Y-type Globe Valve

This valve fixes the issue of high pressure-drop that plagued the Z-type valve. Here, 45o angles are used in the flow channel instead of perpendicular ones, greatly lowering the pressure-drop.

4. Ball Type Globe Valves

Ball valves are a special kind of quarter-turn valve that use a bead-shaped ball with a hole in the middle to regulate the flow of media, as opposed to gates or globes. 

The opening in the centre of the ball, known as a bore or port, allows media to flow through the Globe Valves body when the valve is open and can be closed by rotating the ball 90 degrees. If the valve is closed, the port will be perpendicular to the valve body.

5. Needle Type Globe Valves 

If the flow rate needs to be continuously adjusted, a needle valve is the tool of choice. When flow regulation or throttling is required, a globe butterfly valve is the tool of choice. Form of a plug. The plug of a needle valve is formed like a needle. The stopper on a globe valve is in the shape of a disc.

Parts of Globe Valve
 

Here is an explanation of the different globe valve parts.

-Body

The valve's body provides the framework for the rest of the device. This section includes everything on the inside of the globe valve that controls the regulated substance. To allow fluid to flow either into or out of the globe valve, the aperture of the body features ports  often two or three ports.

-Bonnet

The bonnet is a component of a globe valve's outer ring that seals off the valve from the body. Different varieties of globe valves employ different bonnets, such as those that are bolted in, screw in, or a union bonnet.

There are benefits to using any of these various bonnets. Union bonnets, for instance, are perfect for applications that require frequent cleaning or inspection and also give robustness to the body. 

The pressure is kept out thanks to the simple design of the screw-in cap. Finally, bolted bonnets, which are linked to their bases with bolts, are ideal for use with greater pressures.

-Stem

The stem of a globe valve transmits the actuation force from the disc to the valve actuator or the handwheel. It is one of the most important globe valve components because it links the actuator to the internal workings of the valve

-Cage

Another component of a globe valve is called the cage, and its purpose was mentioned when talking about the seat ring. This cage has been created so that the stem and plug of the globe valve can be protected.

The cage is one factor that plays a role in establishing the flow within the globe valve. Other aspects include: The flow rate can be adjusted by moving the stopper to a different location in the tube.

The flow of the substance that is contained within the valve changes depending on the placement of the apertures and the shape that they take.

-Plug 

The globe valve's plug or disc is a key component. It's movable, physical barrier function allows it to stop or release the flow in a direction perpendicular to the seat. 

By resting against the seat when the valve is closed, the stopper prevents the passage of material, while resting above the seats allows it to pass.Globe valves can have a variety of disc configurations, including those with a composite, ball, or needle. 

The ball type is employed in low-temperature and low-pressure systems, while the composite disc type can give a better shut-off.

-Seat Ring

The seat, along with other globe valve components, serves to fill the gap between the stem/disk and the cover. The valve's seat ring can be tightened by either screwing it in or using torque. The seat, which is also called a seat ring, serves as a secure and replaceable shutdown surface. Cages can be securely attached to the valve's body by using a seat ring.

What is BS 1873 Globe Valves?
 

The BS 1873 Standard outlines the requirements for cast or forged carbon and alloy steel outside screw and yoke globe valves, as well as globe stop and check valves, in straight pattern, angle pattern, and (oblique) Y pattern, with flanged or butt-welding ends in nominal sizes ranging from 15 millimetres to 400 millimetres (in to 16 inches), and classes ranging from 150 to 2500.

When valves of a material composition not included in Section 3 of this standard are needed, it is nevertheless possible to utilize this standard as a general reference. For example, valves can be required for use in extreme cold or very corrosive services.

The standard can be modified so that it applies to valves with needle type seats that have nominal sizes of 15 millimetres and 20 millimetres. These valves will fulfil all of the requirements of this standard, with the exception that the valve seat bore will be reduced, and the needle point may either be integral with or loose on the stem.

What Is Cryogenic Globe Valve?
 

Cryogenic valves are intended for usage in environments that experience extremely low temperatures, as their name suggests. Companies that deal with either liquefied natural gas (LNG) or compressed natural gas are the ones who use them the most frequently as a result (CNG). 

For example, the oil and gas industry makes frequent use of cryogenic temperature ranges that begin at -238 degrees Fahrenheit -150 degrees Celsius. In addition, some gases are said to as "cryogenic," not because of the temperature at which they exist, but rather because the process of compressing their volume calls for more than just a rise in pressure alone. Cryogenic valves are designed to assist in the secure and effective transportation and storage of cryogenic gases.
