How Valves work

[BenAshby]

hi all,
I am a recent graduate and am trying to research and learn about all types of valves. I want to know exactly how they all work. In particular valves with pilot control chambers such as pressure reducing globe valves and roll seal control valves. Does anyone know any good websites that will explain how they work without trying to sell me one? Any replies appreciated. Thanks.

Hi,
You can visit

and click the take a lesson box. You will have a lot of information about solenoid valves. You can also follow the links to selection information or seat materials.
Thanks,
Willy
