How Do Bellows Seal Globe Valves Work?

Bellows seal globe valves work by using a compact structure that includes bellows for sealing the valve stem components. The bellows valve has a bellow inside, and the lower end of the stainless-steel bellows is welded to the stem to prevent the system fluid from eroding the stem. The other end is positioned between the body of the valve and the cover of the valve to create a permanent seal. This double seal configuration eliminates leakage. Even if the bellows collapse, the stem packaging will prevent further leakage. The bellows are welded to the valve stem to ensure stable operating efficiency and prevent the vibration of the valve stem induced by the movement of the valve insert.

What Are the Key Components of Bellows Seal Globe Valve?

The key components of a bellows seal globe valve include the metal bellows, bonnet, the lower end and stem assembly, the upper end and connecting plate, and the sealing surface of the valve disc.
The metal bellows are the main feature of a bellows seal globe valve. They are made by rolling a flat sheet into a tube and then mechanically forming it into a bellow with rounded and widely spaced folds. Inconel is a common material used for making bellows due to its high resistance to corrosion and high temperatures. Cryogenic valves are also commonly made with metal bellows for their ability to withstand extreme temperatures.

The lower end and the stem assembly are welded together, while the upper end is welded on the connecting plate using socket weld. This creates a metal shield between the fluid medium and the environment, ensuring zero leakage from the valve stem. The stem seals are an important component of the bellows seal globe valve, ensuring a tight seal and preventing leaks.
The sealing surface of the valve disc and the valve structure is precisely ground to confirm that it has passed a pressure rating test and that any possibility of leakage is eliminated. Graphite packing is used to ensure a tight seal and prevent any leaks from occurring.

What Industries Primarily Use Bellows Seal Globe Valves?

Bellows seal globe valves are a crucial component in a wide array of industries due to their exceptional sealing capabilities and robust design. The primary industries that utilize these valves are those where the prevention of leakage is of utmost importance, particularly when dealing with hazardous or toxic substances. These valves can be integrated with an API (Application Programming Interface) to provide real-time monitoring and control, making them an even more valuable asset in industries where safety and efficiency are top priorities.Petrochemical Industry: One of the key sectors that heavily rely on bellows seal globe valves is the petrochemical industry. These valves are used in various processes where they control the flow of flammable and potentially harmful substances. Their superior sealing performance ensures that there are no leakages that could lead to accidents or environmental contamination.Nuclear Industry: The nuclear industry is another sector where bellows seal globe valves, classified as ASME Class, are extensively used. In nuclear power plants, these valves play a crucial role in controlling the flow of radioactive substances. The double sealing design of these valves ensures that there is no leakage of radioactive material, thereby ensuring the safety of the plant and its surroundings.

How to Select the Bellows?

  1. Inner Diameter: The inner diameter of the bellows should be greater than the stem diameter, typically 115 mm. This allows the stem to move freely within the bellows without causing any damage.
  2. Outer Diameter: The outer diameter of the bellows is usually selected based on the inner diameter. The ratio of the outer to the inner diameter is generally between 113 to 115.
  3. Wall Thickness, Number of Layers, Corrugations, and Length: These specifications should meet the requirements of pressure resistance, stroke, and cycle life of the corrugated pipe, ensuring that the bellows can endure operational pressures and temperatures.
  4. Bellows Design: For handling higher pressures, a multiply design of bellows (using 2 or 3 piles of the metal wall) is recommended.

Purpose of Bellows in Valves

The primary purpose of bellows in valves is to provide a flexible, leak-proof seal that protects the stem from corrosion and prevents fluid from eroding the stem. Bellows are also used to compensate for changes in temperature and pressure in the system, which allows the valve to operate smoothly and efficiently.

Difference between Bellows Seal Valve and Common Valve

The primary difference between a bellows seal valve and a common valve is the presence of a bellows seal. A bellows seal valve has flexible metal bellows that provide a leak-proof seal and protect the stem from corrosion, while a normal valve does not have this feature.

Meaning of Bellows Seal

A bellows seal is a flexible metal component that is used in valves to provide a leak-proof seal and protect the stem from corrosion. The bellows seal consists of metal bellows that is welded to the stem and a packing gland that secures the bellows in place.

Reason for Bellows

The primary reason for using bellows in a valve is to provide a flexible, leak-proof seal that protects the stem from corrosion and prevents fluid from eroding the stem. Bellows are also used to compensate for changes in temperature and pressure in the system, which allows the valve to operate smoothly and efficiently.

How Bellows Work

Bellows work by expanding and contracting to compensate for changes in temperature and pressure in the system. When the temperature or pressure in the system changes, the bellows expand or contracts to allow the valve stem to move freely, which prevents damage to the valve and ensures smooth operation.

Types of Valve Seals

There are three types of valve seals: packing, mechanical, and bellows.

Packing seals use a flexible material, such as graphite, to provide a seal around the stem. Mechanical seals use a rotating component to provide a seal, while bellows seals use a flexible metal component to provide a leak-proof seal and protect the stem from corrosion.

Two Types of Valve Seals

The two basic types of valve seals are static and dynamic. Static seals provide a seal between two stationary components, while dynamic seals provide a seal between two moving components.

Disadvantages of Bellows

One of the primary disadvantages of bellows is that they can fail over time, which can lead to leakage and other issues. Bellows can also be more expensive than other types of valve seals, which can make them less suitable for certain applications.

Bellows Failure

Bellows failure can occur due to a variety of factors, such as fatigue, corrosion, or mechanical damage. When a bellows fails, it can lead to leakage, reduced valve performance, and other issues. Regular inspection and maintenance can help prevent bellows failure and ensure the continued performance of the valve.

How Does Bellows Seal Globe Valve Work?

The operational principle of a bellows seal globe valve is based on its unique design, which includes a bellows seal that protects the stem from corrosion and prevents fluid from eroding the stem. The valve consists of a valve body, a valve disc, a valve stem, a bonnet, a bellows seal, and packing.

When the valve is in the open position, the valve disc is lifted away from the valve seat, allowing media to flow through the valve. The stem and the disc move together as the stem is rotated by the actuator. When the valve is in the closed position, the valve disc is pressed against the valve seat, preventing media from flowing through the valve.
