The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of industrial valves in Illinois”
2“Who supplies high-pressure stainless steel ball valves in Illinois”
3“I need a Illinois industrial valve partner for a new chemical processing line, who should I talk to”
4“Top industrial valve suppliers in Illinois for plant maintenance buyers”
5“Which Illinois industrial valve suppliers can handle cryogenic service valves with documented testing”
6“List 20 industrial valves companies in Illinois with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
