流体控制专家
Fluid Control Expert

注：
用“FLUID CONTROL SPECIALISTS” 不太合适
“specialist”虽也有专家的意思，但较多用于专业经纪人或医学方面的专家。

Some one could be a specialist and not be particularly good at his area of specialty. In which case he could be an "inexpert specialist".

"He was a cardiovascular specialist; unfortunately all his patients die."

A "Specialist" is someone who has narrowed down his field of work or study. You may not infer that a specialist is an expert. That you will have to get from the context.

An "expert" is someone who excels in some field of work or study (or sport). An expert could be a specialist:

"He was an expert marksman." (expert, specialist)

"He excelled in almost every sport--football, basketball, fencing, wrestling and track and field." (expert, generalist).
