I am new to Google Groups. I have not used this system before.
I was looking for some information online. As you all know how difficult it is to find something in this sea of information, most of it which seems like garbage to my/our specific needs.
I was wondering if someone could guide me towards getting information on Pneumatic Valves and Solenoid Valves.
I don't know if I could get more specific or not, but I was looking for design features, and materials.
If you search google for groups with posts on your keywords, you will find opinion, much like you see in the other posts in this group for example.
It seems to me you would be better served to search google WEB with the same keywords. The hits you get will come from suppliers, from training materials sources and the like.
If you are unfamiliar with the search engine approach - one of the few, I would say, then here are a coupla hints.
Most any keyword will result in thousands of hits, and one way of trimmimg them is by disallowing spread instances of keywords, such as pneumatic up here, and valves in the next para.
Fix the pairs by quotes, e.g. "pneumatic valve" "solenoid valve". and add "design feature" "material". That does for the keywords.
The next bit is most important - it is the patience to sample some of the long list of hits, on several pages, looking for exactly the kind of material that you want.
If none of them fill your needs, change a keyword - sometimes a minor deletion or amendment pulls up a better style of hit for your purpose.
You choose the material based on the compatibility with the fluid, temperature, frequency of operation, pressure, type of actuation, etc. General requirements will get you lost on the internet. If you have specifics, you can narrow things down.
