Connection issues with valves
Thread Content
The inner diameter of the pipe being used is 100 mm; what is the minimum diameter of valve that can be connected, and what is the maximum diameter?
It depends on what kind of valve it is. If you have a flanged valve, then only a valve with a size of 100 can be used, as you won’t be able to connect other types of valves. But if it’s a welded valve, then it doesn’t matter, as you can use reducers to connect the valves. Provided that it meets your process requirements.
Valves with flange and clamp connections have the same diameter as the pipeline, so only size 100 can be used； The butt welding method allows for a change in diameter, but this change should be made according to the requirements of the manufacturing process; it’s not advisable to make the diameter too small or too large. In my opinion, a change to 125 or 80 is fine. The rest remains to be verified.
Basically, they are flanged, threaded, or welded; for sanitary applications, there are things like clamps and the like! However, flanges and threads are used quite frequently, and there are many standards related to flanges that need to be taken into consideration.

It can connect valves up to DN100 at the maximum, and valves of DN1100 or DN40 at the minimum; in other words, the connection fitting is DN100, while the valve seat is DN40
You can use a reducer with different diameters to connect the valves
In my opinion, it can only be connected to valves with a slightly smaller diameter; it cannot be connected to valves with a diameter larger than 100, as that would be pointless
Yes, it can be connected using tapered joints; check whether to use a flat bottom or a flat top.
Theoretically, does that mean that by using different sizes, the diameter can be changed arbitrarily?
To address this issue, one must first consider what the requirements of your process are – factors such as the flow rate, velocity, and resistance in the pipelines. All of these change after valves are installed, and the size of the valves has a significant impact on these factors. The key question is what size of valve is suitable for your process requirements. In theory, it would be possible to use a blind flange on the pipeline, which would result in a flow rate of 0.......................
