Downstream consequences of flashing through a globe valve
Downstream consequences of flashing through a globe valve
(OP)
I have a situation where where water will flash through a globe valve to an an open basin downstream. There will be some piping downstream of the valve before emptying into the basin. What (if any) are the issues I need to consider with regards to the downstream piping arrangement?

I work with valves in exotic alloys at alloy-valves.com. This is our blog, and this is me on Twitter and LinkedIn. Let's connect!

As hsbcn points out, you can find a lot of information using the search function incorporated in this siteand this forum.
Essential here is for you (as always), purpose, flow and pipieline details. The more spesific question, the more specific answers you will get.
I also observe that the thread from hsbcn does not mention solution of the cavitation problem using other types of valves then globevalves, and alternative solutions for larger diameters (above 4") that possibly could be of interest.
Thread below points to RKV needle valves (wide regulation without cavitation, the factory has to advice on solution and dimension, with air inlet if pipieline after valve. See also double eccentric ball-valves, outlet without regulation. (Competitors have similar solutions for both types.
