Abstract
In each hydroelectric power station, one of the outstanding systems is the power channel, which provides water flow to the hydroelectric power generators. On this power channel, there are two or more special valves that can interrupt the flow in specials conditions. In this specific application, there are two butterfly valves and the two command systems, placed together into a special underground room, called "valve house". The function of the each system is to allow the water flow reach the generators by keeping the valves opened (0 - 5 degrees) and to avoid the overflow of the underground power station in some cases. These two systems are conected by electrical signals, in order to increase safety in use by detecting malfunctions and to close at least one valve.
