Best Answer

You'll need to be more specific, since valves are used in many different applications.

What type valves are you posting your inquiry?

Since the topic is under "new electrical work", one might assume that you are asking about electrically operated valves or valves with position sensors, or you may be asking about the old "vacuum tubes", which in much of the world are referred to as "valves".

Answering all of those questions would end up being a dissertation, and probably more than would be appropriate for Answers.com
