Valve End Connections - Selection

          Valve end connections are important parts that connect the body of the valve to the waterway or other equipment. What kind of end connection a valve has depends on what it is used for, what kind of material it is moving, and how it is being used. In this piece, we'll talk about the different kinds of valve end connections and what makes them unique.


Types of Valve End Connections


1. End connections with a flange

          Most valve end connections are flanged end connections, which are used in a wide range of situations. Flanged end connections are made with raised faces that fit into flanges on the pipes or other equipment. The raised faces keep the valve and the pipe from leaking by making a tight seal. Flanged end connections are easy to put on and take off, which makes them good for situations where valve repair needs to be done often.

2. End connections with threads

          When valves need to be linked directly to pipes or fittings with threaded ends, threaded end connections are used. Threaded end connections are good for low-pressure uses and are often found on small valves. Threaded end connections are easy to set up and need very little maintenance. This makes them perfect for situations where valve maintenance doesn't need to be done often.

3. Connections at the Socket Weld End

          Socket weld end links are used in situations where there is both a lot of pressure and a lot of heat. Socket weld end connections are strong and don't leak because they have a socket that is soldered to the pipe. In steam and gas uses, socket weld end connections are often used.

4. End connections with a butt weld

          Butt weld end links are used in situations where there is both a lot of pressure and a lot of heat. Butt weld end connections are strong and don't leak because they have a bevelled end that is bonded to the pipe. End connections made with a butt weld are often used in oil and gas pipes and chemical processing.

5. Connections at the lug ends

          When the valve needs to be fixed between two flanges, lug end connections are used. The bolts that hold the valve between the two flanges are linked to the lugs at the end of lug end connections. Most of the time, lug end connections are used when the valve needs to be taken off without affecting the waterway.

6. Connections at the wafer ends

        When a valve needs to be fixed between two flanges without using bolts or nuts, wafer end connections are used. Wafer end connections have a raised face that lets the valve fit between two plates without using bolts or nuts. Wafer end connections are often used on small valves and in places where valve repair needs to be done frequently.


Factors to Consider when Choosing Valve End Connections

1. Pressure and temperature needs

The type of end link needed will depend on the pressure and temperature needs of the application.

2. The type of fluid that is being transported

The material needed for the end link will depend on the type of fluid being moved.

3. Maintenance requirements

When choosing the type of end connection, you should think about what kind of maintenance the valve needs. Some end connections require frequent maintenance, while others require minimal maintenance.

4. Needs for installation and removal

When choosing the type of end connection, you should think about how the valve needs to be installed and remove. Some end links are easy to put in and remove, while others need tools and equipment that aren't common.

Conclusion:

Valve end connections are important parts that connect the body of the valve to the waterway or other equipment. The most common types of valve end connections used in different situations are flanged, threaded, socket weld, butt weld, lug, and wafer. When choosing a valve end connection, you should think about the pressure and temperature needs, the fluid being moved, the upkeep needs, and the installation and removal needs. By choosing the right end link, you can make sure that the valve works well, is reliable, and is safe.
