Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Massachusetts. They belong to that state's ranking, not this one.

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