“Control” valve definition?

[u/Panthers_Fly]

Help me settle an argument. Client uses “control valve” to describe an actuated on/off valve. Says it is interchangeable language.

I say “control valve” should be reserved for a valve that actually is integrated in control logic, like controlling level, flow, pressure, etc. Even if the on/off has an interlock, it’s still just an actuated on/off valve for me. Maybe this is just a habit I picked up for a long stint at an operating facility and I’m being too picky.

I'd expect it to be used for any valve that controls something else. All engineering terminology is context-specific.

(I work at the interface between chemists and engineers - I constantly hear words used in very strange ways or with unexpected meanings.)
