All of them are fine; the bellows-type stop valves definitely provide double sealing
Ordinary ones are sufficient for low-pressure steam stop valves
A regular globe valve is more than sufficient for 0.5 MPa; diaphragm globe valves are too expensive
A regular stop valve is sufficient; bellows valves are much more expensive and not necessary.
It’s not a big deal if steam leaks out; there’s no need for such advanced devices as bellows valves
Low-pressure steam can be used; bellows are expensive
Why use a bellows stop valve?
