Valve turning

[Jorbar1551]

What is better, a knob that will shut on and off quickly with less than 2 turns, or one that takes multiple turns before it turns off?

 

[Hyper-limits]

One that takes multiple turns to shut off.

One that takes multiple turns to shut off.

Why?

less likely to get shut off accidently

If you are in overhead env or even just under a line of some sort and it somehow rolls the valve, it could get turned off if it only has a short "throw".

Having a long throw isn't going to do squat to stop having a rolloff. The difference between a short throw and a long throw is about 2-4 inches of contact. You need to be checking it after anyway with every contact so who cares?

I prefer short throw because its marginally faster to shut down in an emergency and doing valve drills won't give me hand cramps.

Is a "soft turnon" or the ability to more feather a freeflow on and off with better control a consideration when choosing a valve?
