Nice , doesn’t lose a drop! if you could just hold firmly the camera it would be an interesting video, we can’t even tell if shaft is horizontal or vertical
what kind of diameter and pressure is this running because i work in water treatment and i never saw a driveshaft of that size for a valve, the biggest stuff we operate is around DN1400 at a maximum of 40 Bar. Just Wondering :D
What is the fastest safe time to go from fully closed to fully open and generating power? I thought it was 17 seconds (from ~1998 UK Uni hydro study). Here, it looked like 60 second alone for the SpV/MIV?
Nice to see the operation. Spherical Valve & Francis turbine. Thanks for sharing.
Seeing that valve close on that counterweight alone would be interesting, but I wouldn't want to be there in person when it happens.
That is one hell of a drive shaft!
That variable vane assembly is impressive!
Where is the air injection to stop water turbine damage?
So not one but two of Thors Hammers as counter weight balance on that rotary valve lol awesome.
If those hydraulic openers totally fail and the conterweights close the valve quick I wonder how much of the building would be left.
Imagine the water hammer effect if that MIV Hydraulic could blow and slam closed! I know it can't but it's crazy to think of!

This is amazing!
That was the coolest boring video I’ve ever watched 👍🏻🇺🇸
Why, that's just a fancy-pants 1/4 turn valve! 🧐 😉 Cool video, thanks for sharing.
As the Guide vane is still closed, how spinning of turbine works

this is nuts!!
Main inlet valve MIV or guide barig are open but not hold how to solve it
What the function of by pass valve ? Is it for equalizing pressure ?

Good video. What is maintenance seal and service seal?
