The pressure set point of the PSV so that the weakest point of the associated system (pipeline, vessels, etc) can be protected by the PSV. That is, the set point is normally set at the MAWP of the system. Also, take a look at the over pressure accumulation of the PSV which depends on the type of...
physically no difference, not that I know. Maybe I can learn a thing or two here but not that I know of. PCV and FCV have the same built. Trims, bonnet, stem, positioner, actuators, etc.
The wet parts are the most important as the built are dependent of the fluid characteristics (fluid state...
It's not a concern here. It's in gas state so cavitation won't occur. Your gas temperature need to be really low at a certain pressure to change it to liquid, which is not going to happen in your case. No liquid, formation of bubble is not going to happen.
Cavitation occurs when the liquid...
