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.
Here are some other types according to the type of body of globe valves;
● Y types
● Z types
● Angle Types
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.
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.
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.
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.
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.
You should also consider some below points:
Regular maintenance of the valve should be needed. You should pay attention to check there is no valve leaking.
If the valve is not working regularly, then cycle the valve. It will prevent the disc from bedding itself in the seat.
You can use a grease gun to grease the crossbar on the nipple. If needed, you should lubricate the spindle.
If packing needs adjustment, you should need to tighten the gland bolts slightly. The gland will be damaged if you over-tighten it. You need to replace the packing if leaking through the gland appears.
Ball valves are used for many years for controlling media in plant piping. A ball valve may lasts for 8-10 years if you follow the bellow tips about its management.
One of the most common uses for globe valves is bypass lines. Bypass lines reroute fluid around a closed system. Globe valves are installed to control fluid flow in the bypass line. This is because globe valves can easily open and close, offering high precision when controlling fluid flow. As a result, globe valves are an essential component in many types of bypass systems.
