There are various types of end connections that a valve can have. Depending upon the types of applications the valves are being used for, you can choose the right type of end connections. The common types of valve end connections are as follows:
Flanged Valve End Connections – These are one of the easiest connections to be installed or uninstalled from a pipeline. These are also one of the most commonly used end connections at present. As these are fastened to the pipe flanges, assembling or disassembling them is quick and easy. These are usually available in sizes from 15mm onwards.
An important point to be mentioned about these types of end connections is that they are secured with several bolts. Thus, they ultimately need less tightening torque than what a threaded end connection requires. Hence, flanged end connections can be effectively used for various types of valves.
Threaded Valve End Connections – These types of end connections are suitable for low pressure piping systems. These are affordable and ensure quick assembly to the users, without any difficulty.
In some cases, these connections may be welded around the joint, once they are assembled. However, this is not much in practice as it may cause some troubles in the efficient use of these types of valve end connections.
Socket Weld Valve End Connections – These types of connections are socketed so as to have a plain spigot end of the pipe. These are used on valves that are made up of steel, and for such applications that require higher pressure and/or higher temperature in pipelines that do not necessitate repeated disassembling. They ensure leakproof connections, that too for a long time span.
Butt Weld Valve End Connections – These types of end connections are manufactured in such a manner that each end of the valve is bevelled to match with the thickness and bevel on the pipe. After this, the two ends are butted to the pipeline and are welded.
They are used on steel valves, and as they have greater strength, they are perfect to be used for such applications that require higher pressure and/or temperature in pipelines.
Also, these are ideal for all types of valves, and for use in those areas where repeated dismantling is not required.
