What’s The Difference Between A Globe Valve And A Butterfly Valve?

The main difference is in times of operation when you find differences between the butterfly valve and the globe valve. The working of both valves is different due to their structure composition. The globe valve lifts the stem when it opens up or closes. It means that the rotation of the hand wheel occurs that lifts along with the branch.  But the disc of the butterfly valve turns around its axis to cut and throttle the flow. The butterfly valve is indicated by its lightweight, small volume, simple structure.

Why Does Globe Valves Less Than 100mm In Diameter Have Low Entry And High Exit?

When opening, the globe valves are designed with an inlet low and outlet high to lower the flow and save effort. Conversely, the shut between the valve casing and bonnet is not stressed when the valve is closed. It will not be affected by the temperature and pressure of the medium for a long time. It also reduces the probability of leakage. Also, the stuffing can be added or changed when the valve is closed, which is easy for maintenance.

Why Use A Bellow Globe Valve On The Heat Transfer Oil Pipeline?

In heat transfer, oil pipeline transfer often causes corrosion and other problems. The corrosion will affect the bellows differently, shorten life, and even damage. To prevent this damage, you can use the bellow seal valves. We have described why the bellow seal valve is used in heat transfer pipelines. If you have a question, contact us happily.

How to Choose a High-Temperature Valve In A Chlorine Environment?

While choosing a high-temperature valve in a chlorine environment, you must consider the following factors. The material from which the valve is made up, its design, and up to what temperature it can work efficaciously. You should also keep in mind the potential threat and chloride ion corrosion a valve can face. High-temperature valves are often used in chemical, power, petrochemical, and other industries. The long time uses of high temperatures will impact on physical effects of materials. Before selecting extreme temperature valves, we need to focus on temperature or factors.

What Is The Difference Between One-piece Ball And Two-piece Ball Valve?

The single piece ball valve has a complex cast body which lowers the risk of leakage. This structure gives a reduced number of opportunities for leakage. The valve seals and trim are added through one of the end connections. Once the valve is placed, it can only run by removing the entire valve assembly from the piping system. One-piece ball valves are generally not repaired and are inexpensive.

In contrast, two-piece ball valves consist of two separate pieces. One piece has one end connection and the body. The second piece fits into the first, keeps, and includes the second-end connection. They have a second piece that fits into the first, giving the second-end reference.

What Is Stainless Flanged Ball Valve?

These stainless flanged ball valves, used to regulate water flow in your home. Liquids and gases are controlled with stainless steel flanged ball valves. It consists of a ball fitted with a handle that can be turned to open or close the valve. When the handle is turned to the open position, the ball moves out of the way and allows fluid to flow through. When the handle is turned into the closed position, the ball rolls into the path of the liquid.

How To Install Stainless Steel Flanged Ball Valve?

The installation of the flanged ball is done with the following steps. When the front and back pipes should be parallel to the sealing surfaces of the two flanges, clean the pipelines of impurities in the channel. Check the flange ball valve’s symbol and the valve’s working. At both ends of the connecting flanges, remove the protective parts of the flange ball valve. The check valve is fully complete from dirt.

How Should The Globe Valve Be Installed Correctly?

The globe valve working process from the working floor must be about 1.2m. It should be set to shut off the valve operating platform when the base of the hand wheel is more than 1.8m. Cut-off valve more pipeline help the installation of the valve for easy processing. The average distance between the hand wheel does not exceed 100mm.
