MAIN INLET VALVE CLOSING

The main inlet valve in a hydro power plant is typically a large valve located at the intake structure of the penstock, which controls the flow of water into the turbine. It's a critical component for regulating the water flow and thus controlling the power generation of the plant.

Since 2016 in Australia a test was run that gave dams a retro fittable system that meant a dam could have three turbine halls with no issues . this test was run in NSW in a town called Gosford and i bet you have never heard of us. More power from the same volume of water .. RDP Marine is the name

What is the function of the weight?

[@bernhardweiss1309]

For closing the valve without hydraulic pressure in case of an emergency

Also allows the designer to use a single way ram, which is stronger and smaller than a two way ram. Mostly a fail safe design feature.
