How does the Bellows Seal Globe Valve work? 

Turning the actuator or the handwheel, the stem will rise along with the disc away from the seat, which allows the material to flow through the valve. 

But when you turn the actuator in the opposite direction, the stem will push the disc against the seat. So, it will block the path for materials to flow through. 

While the material goes through the valve, the other components are also working for smooth performance. To illustrate, the bellow stretches and folds to keep the material from being carried out around the stem as it moves.

5 Types of Bellows Seal Globe Valve

Flanged Bellows Seal Globe Valve

This bellow seal globe valve has a connection that features raised flat rims on both ends called flanges. This makes it easy to install and remove for regular maintenance or repair.

Y Pattern Bellows Seal Globe Valve

Notable for its unique  “Y”-shaped body. As a result, the material may travel more straight across the valve than by the other types. This will help reduce pressure drops because the material does not need to change direction inside the valve.

Extended Bellows Seal Globe Valve

These globe valves consist of longer bellows than the other types. The expanded bellows increase the valve’s protection from potential hazards such as leaking, particularly for high-temperature and high-pressure applications.

Welded Ends Bellow Seal Globe Valve

Its bellow seals’ ends are already tightly attached to the stem. So, it had a permanent and strong seal unlike other valves, making them suitable for high temperature and high pressure working environments. 

Socket-welded Bellows Seal Globe Valve

It has a circular aperture at both valve ends where the pipes can be placed directly. This results in an effective, non-leaking connection.

How to Choose the Best Bellows Seal Globe Valve Manufacturer?

There’s a lot of factors to consider when choosing the right bellow seal globe valve manufacturer. 

One of them is to look for a manufacturer has certifications that show they follow international standards like ASME and API. This ensures their commitment to creating high-quality products.

Another factor is to analyse the manufacturer’s experience in the field of creating valves and their product range. Longer experience in manufacturing and having a wide product range will ensure they can meet the customers unique requirements for application.
