I'm designing and building a simple valve receiver as a Corvid-19 lockdown project. I'm not sure whether screening cans on the valves are useful, necessary or detrimental to performance and service life. When I look at commercial equipment there seems to be no rhyme nor reason to it.

Can anyone offer reasons for fitting screening cans, or not?

Thanks,
