Recommended Velocity for 132" Butterfly valve
Recommended Velocity for 132" Butterfly valve
(OP)
Hello, I would like to know what is the max. recommended flow velocity for a 132" butterfly valve used as a water regulating valve in a dam. The water head is 125 feet.
I have looked on the AWWA standards but they only cover valves up to 72".
Thanks,
