What is the difference between a pressure gauge stop valve and a valve used with a pressure transmitter?

What is the difference between a pressure gauge stop valve and a stop valve located beneath a pressure transmitter? Some people say that the pressure gauge stop valves have internal threads, while those used under pressure variations have external threads. There are some doubts – both external threads and internal threads should work, right? :handshake
There is no difference between the stop valves for pressure gauges and those for pressure transmitters; they are generally determined based on the pressure rating, temperature, medium used, as well as the connecting pipes
There are also those with flanges. Since the connection pipes connected to pressure gauges are usually DN25 or smaller, the valves attached to these pressure gauges and pressure transmitters have a shut-off function. It depends on the medium; for ordinary media, threaded connections can be used, while for flammable, explosive, or toxic media, flange connections are generally employed. It is used in the same way as the valves on pipes
In short, it’s the same: after the pressure tap valve, one can connect either a pressure gauge or a pressure transmitter, or even both of them to the same valve.
It’s just a valve; whether it has external threads or internal threads makes little difference – either type can be used. The choice between internal and external threads depends mainly on the interface of your pressure gauge or transmitter.
There is no difference between the stop valve on the pressure gauge and the stop valve attached to the pressure transmitter; either one will work. You just need to raise the requirements.
We commonly use external threads and ferrules; external threads, flanges, or other forms are used very rarely.
Yes, I think it’s the same. Sometimes a pressure gauge port is provided on the equipment, and then an on-site pressure gauge as well as a remote-transmitted pressure gauge are connected to it. There’s no difference, right?
:Lol, it’s the same; there’s no difference
