Are there any components designed to prevent excessive leakage of the medium in case the pressure gauge’s pressure-bearing parts fail, components similar to one-way valves?

Is there any component that can prevent a large amount of fluid from leaking out in the event that the pressure gauge’s pressure-bearing parts fail, something similar to a one-way valve – a component that can seal itself off immediately in case of failure to stop any leakage?
What the poster is referring to is probably the function of the steel ball found inside the one-way valve used in glass plate or glass tube level gauges. It seems that no pressure gauge tapping valve currently uses such a design; however, it should be possible to implement this mechanism in needle-type valves and stop valves used for pressure tapping.
That’s exactly the function of the stop valve – it needs to be closed manually. . It cannot be automatically terminated
There isn’t one at the moment; generally, root valves are used for closing. If there is a leak in the pressure-bearing components, it could be due to quality issues, excessive pressure, or problems with the material chosen for construction – this is an individual case
